CB E1 24DC/1A S-R P - Electronic circuit breaker
Electronic circuit breaker, 1-pos., active current limitation, status output and reset input, plug for base element.
- Individually adjustable with protective plugs
- Protective plug with fixed nominal current value as protection against unintentional changes
- Active current limitation to improve the capacity of the upstream power supply
- Remote reconnection with the reset function
- Increased system transparency with integrated remote message function
Technical Specifications
Notes
| General | When mounted in rows without convection cooling, the nominal device current should only be led to a maximum of 80% due to the thermal effect during continuous operation (100% operating factor).Special precautionary measures must be taken in systems or machines, to prevent components from restarting (e.g., use of a safety PLC).Parallel connection of multiple circuit breakers is not permitted. |
