All machines that could cause personal injury upon automatic re-start,
e.g. drilling machines, electric saws, meat cutting machines etc.
The X3120-U02 version allows set up of a cost-effective safety
circuit via the physically isolated undervoltage release module, which
enables implementation for example of a remote disconnection with
emergency stop.

The undervoltage release module reliably excludes personal injury
through automatic re-start after voltage dip or power failure.
Note: Basic unit 3120-N...-H7 or -G7 requires screw terminals. Not
possible in combination with PT terminals.
Please observe the following in combination with design version 4:
In the event of voltage dip or power failure, the undervoltage release
module trips the circuit breaker.
The rocker actuator will go into centre position. Reset is effected
in two steps:
Step 1: Switch rocker into OFF position.
Step 2: Reset circuit breaker.
