IOTB2 series product documentation released
This product update gives a consolidated overview of the IOTB2 standalone smart circuit breakers, the modular smart circuit breakers and their gateways. The content is drawn from existing product documentation and focuses on structure, number of poles, current range and communication method.
Standalone and modular products
The standalone product pages summarized here are mainly 2-pole and 4-pole, with rated currents from 6 A to 80 A; the certificate coverage may differ from what the pages show, and the certificate documents take precedence. Modular products consist of a gateway and circuit breaker modules and cover 1-pole to 4-pole configurations; the rated current steps are not identical for every number of poles.
IOTB2 document scope
| Product category | Contents of this compilation |
|---|---|
| Standalone product pages currently listed | 2-pole, 4-pole; 6 A to 80 A |
| Modular smart circuit breaker | 1-pole to 4-pole; rated current listed by model |
| Companion gateway | Model mapping for 4G, wireless LAN, RS485 or wired LAN |
Gateway communication
The gateways are the GWY-4R, GWY-WR, GWY-WRL and GWY-RL. Their uplinks are, respectively, 4G, wireless LAN, wireless LAN or wired LAN, and wired LAN; all four communicate downstream with the circuit breaker modules over RS485.
