The undervoltage release module reliably excludes personal injury
through automatic re-start after voltage dip or power failure.
In the event of voltage dip or power failure, the undervoltage release
module trips the circuit breaker. The rocker actuator will go into cen-
tre position. The breaker can be reset in two steps:
Step 1: Switch rocker into OFF position.
Step 2: Reset circuit breaker.
Note: Basic unit 3120-...-H7 or -G7 requires screw terminals. Not
possible in combination with PT terminals.
