Remote reset magnet (RR)
With the remote reset magnet (RR), the circuit breaker can be reset remotely when the
trip unit has opened the circuit breaker.
Deliberate resetting of the ETU by mechanical operation on the device or remote resetting
via the RR is necessary for safety after overcurrent tripping. All faults in the distribution board
should be cleared first.
The reset coil is available for different voltage supplies.
