What is the difference between Plug-in and Fixed Circuit Breaker ?
The plug-in version makes it possible to:
- Extract and/or rapidly replace the circuit breaker without having to touch the connections on the base
- Allow for the addition of future circuits by installing bases that will be equipped with a circuit breaker at a later date
- Isolate the power circuits when the device is mounted on or through a panel. It acts as a barrier for the connections of the plug-in base. Insulation is made complete by the mandatory short terminal shields on the device.The degrees of protection are: circuit breaker plugged in = IP4
circuit breaker removed = IP2
circuit breaker removed,base equipped with shutters = IP4.
