How is terminal overtemperature handled?
An abnormal terminal temperature enters the alarm or protection handling process and, where necessary, can trip the breaker or be reported to the platform. Terminal overtemperature is usually linked to loose connections, abnormal loads or a rise in ambient temperature, and the cause should be investigated on site promptly.
Can three-phase imbalance and phase loss be monitored?
Yes. Three-phase imbalance and phase loss are major three-phase power-use abnormalities. The device monitors them and reports alarms, helping O&M staff detect phase-sequence errors, phase loss, load imbalance or supply abnormalities in time.
How can accidental remote closing be avoided during maintenance?
During maintenance, use the local maintenance switch, safety lock, or open-position lockout first, and complete tagging, power isolation, and verification in accordance with site procedures. Remote control cannot replace on-site safety checks; preventing accidental closing is the top priority during maintenance.
When should open-position lockout be used?
Open-position lockout is intended for maintenance, fault isolation, equipment servicing, or any situation where the circuit must remain de-energized. Before applying it, define the operating permissions and restoration procedure so normal service can be restored safely.
Can alarms be graded by level?
Alarm information can be managed as faults, alarms and status events. Short-circuit, leakage, overtemperature, arc fault and three-phase abnormality messages should be handled first; remote switching, scheduled actions and similar events are better tracked as status and operation records.
How should I choose between 4G, Wi-Fi, and RJ45?
4G suits projects that have no stable wired network on site or need an independent connection; Wi-Fi suits small, short-range installations where router coverage is stable; RJ45 suits projects that already have a stable LAN and require centralized management. The choice also depends on the number of devices, the gateway type and how the platform is connected.
Do the Wi-Fi products support 5GHz?
Wi-Fi products should preferably be configured on a 2.4GHz network. During installation, keep the circuit breaker at a suitable distance from the router and avoid metal obstruction and weak-signal environments; when the on-site network is complex, 4G or RJ45 solutions can be evaluated first.
What should be checked first when the communication signal is unstable?
If the communication signal is unstable, first check the device power supply, gateway online status, indicator lights and the router or network environment; then check the RS485 wiring, sub-device order or address settings, IP settings and platform binding. For Wi-Fi installations, also check the distance and any metal obstructions.
Can users install the product themselves?
Installation by unqualified users is not recommended. Smart circuit breakers involve mains wiring, live and neutral terminals, three-phase conductors, and protective-earthing identification. Installation must be performed by a qualified electrician or other competent person in accordance with the wiring diagram and installation requirements.
What needs to be confirmed before installation?
Before installation, verify the input voltage, wiring order, live and neutral conductors, terminals, available space in the distribution board, number of circuits, number of poles, communication method, gateway location, and platform account readiness. Thorough verification reduces commissioning work and rework later.
What needs the most attention during wiring?
When wiring, connect the incoming, outgoing, neutral, live and three-phase conductors strictly according to the wiring diagram, check that the wiring order is correct and the terminals are tight, and do not connect the neutral N to the protective earth PE. Check the supply voltage and the wiring again before switching on.
How does a modular circuit breaker connect to the gateway?
Modular circuit breakers are usually connected to the system centrally through a gateway. On site, wired links such as RS485 or RJ45 can be used, and wireless links such as 4G, Wi-Fi or NB can be combined with them to connect to the platform. The actual connection depends on the gateway type, the number of devices and the site network.
What should I check if provisioning fails?
If provisioning fails, first confirm that the router is working normally, the network is 2.4 GHz, the account and password are correct, and the device is powered, then check the distance and any obstructions between the circuit breaker and the router. After repeated failures, try restarting the device, provisioning again, or binding by searching for the device name.
What is the most important preparation before project deployment?
The most important step before project deployment is to complete the site survey and solution confirmation, covering the number of circuits, rated current, load type, distribution-board space, communication method, gateway location, platform account, and document version. With thorough preparation up front, installation and commissioning go more smoothly afterwards.
What projects is the platform suitable for?
The platform suits projects that need centralized monitoring of electrical safety, device status, alarms and energy consumption, such as business and industrial estates, commercial buildings, industrial sites, schools, hospitals, property management and multi-site power-use management. Its value lies in improving O&M efficiency, the speed at which abnormalities are detected, and power-use management.
What device data can be viewed on the platform?
The platform shows voltage, current, temperature, leakage, power, energy, device online status, alarm status, group information, operation records and more. What each project can display depends on the device models, how devices are connected and the permission settings.
What does alarm management include?
Alarm management typically includes real-time alarms, pending alarms, historical alarms, alarm notification configuration, device alarm queries and mobile notification management. O&M staff can use alarm records to trace when an abnormality occurred, where the device is located and how it was handled.
Does the platform provide statistical reports?
The platform supports energy consumption statistics, alarm statistics and multi-dimensional report export, and data can be viewed by user, group, device and other dimensions. Reports can be used for O&M review, energy consumption analysis, abnormality statistics and project management.
Can the platform help with energy-saving management?
Through power-use monitoring, energy consumption statistics, anomaly detection and trend analysis, the platform helps identify abnormal loads, wasted energy and management blind spots. It provides data to support energy-saving management; the actual savings depend on the site loads and the management strategy.
Can the platform integrate with fire protection or smart city platforms?
The platform can be integrated with fire-protection, smart-city or third-party management platforms as the project requires. The actual integration scope depends on the interface method, data content, permission scope, project system architecture, and technical confirmation by both parties.
What information should O&M staff focus on day to day?
In daily operation, O&M staff should focus on device online status, key electrical parameters, leakage and temperature abnormalities, alarm handling status, group control records, energy consumption trends and report data. Circuits with frequent abnormalities should be checked first for on-site load and wiring problems.
Does operating through the app replace on-site safety inspections?
Operating through the app is not a substitute for on-site safety inspections. Remote control and smart-home linkage suit day-to-day management, but maintenance, wiring, energization, fault handling and power restoration should still follow on-site safety procedures and be confirmed by qualified personnel.
The device is installed on site but does not appear on the platform. What should I do?
If a device is installed but does not appear on the platform, first check the device power supply, whether the gateway is online, the communication method, the sub-device order or address settings, the IP or network settings, the platform binding and whether the device SN is correct. Where RS485 is used, also check the wiring order, address and terminal connections.
What should I check when remote control fails?
If remote control fails, check in turn the device online status, network communication, platform permissions, group assignment, alarm or lockout status, the on-site switch position and the gateway connection. Do not force a remote close while the breaker is under maintenance or locked out.
What are the common development integration methods?
Common integration options are the gateway protocol, SDK, API and Modbus. Customers with an existing platform can consider the API or the gateway protocol, those with their own gateway or serial display are better served by Modbus, and customers who want a quick integration can consider the SDK.
Which customers are best suited to an SDK integration?
SDK integration suits customers who want to reduce the work of parsing low-level protocols and shorten the development cycle. Customers can call the SDK's packaged commands to complete device onboarding, data reading, and control logic development, but servers, accounts, and permissions still have to be configured.
Which customers are best suited to a Modbus integration?
Modbus integration suits customers whose self-developed gateway, serial-port display, or on-site system reads sub-device data directly. It leans towards field-side integration, reading registers through the 485 port and parsing real-time data and alarm information.
Which scenarios are best suited to API integration?
API integration suits scenarios where customers already have a cloud platform or business system and want to obtain device data, alarm information, or control capabilities cloud-to-cloud. Interface scope, permissions, and data fields must be confirmed project by project.
How should customers building their own gateway select models?
Customers building their own gateway should focus on modular 485 sub-devices, the Modbus data-reading method, the number of devices, on-site wiring and power supply conditions. When selecting models, first determine which protocols the gateway supports, then confirm the sub-device models and the number of circuits.
What information should you prepare before integration?
Before development integration, prepare the server address, account permissions, device SN, protocol method, data fields, control permissions, test environment, integration objectives, and security requirements. The more complete the preparation, the more efficient the joint commissioning.
Can the server endpoint be changed?
The server endpoint can be adjusted as needed for the project. This belongs to project configuration and integration work and should be handled by authorized technical staff in coordination with the account, network, and platform environment.
Is OEM or custom development available?
Customization can be discussed for the device itself, communication connectivity, platform software, branding, project documentation and selected functions. Whether a specific customization is possible depends on the target market, certification requirements, volume production conditions, delivery lead time and technical feasibility.
