Remote tripping
Remote tripping is possible by means of a shunt trip (MX+OF) or undervoltage
release (MN). A tripped device is indicated by a red indicator flag on the front panel.

v equipped with an O + F switch that indicates the “open” or “closed” position of the
device

b When the voltage drops to 70–35% of the supply voltage, the associated device
trips and is prevented from reclosing until the supply voltage is restored:
v uses emergency stop via push button
v uses safety feature on circuit supplying several machines preventing uncontrolled
restarting of the motors.
