- Earth leakage protection/ reclosing parameters.
- Protection trip current.
- Number of reclosures
- Protection status messages, etc.
Device with three output relays, one for indicating locking status and the other two for the trip and subsequent reset of the circuit breaker (MCB-P). It is only used with the MCB-P, with it not being possible to associate it with others. It has voltage-free input for remote control trip/ reset operations.
