Magnetic Fault Indication Device

The magnetic fault indication device either differentiates a thermal fault from a magnetic fault or opens

the contactor only in the event of a thermal fault (see page 18).

Undervoltage Trip GV7AU

The undervoltage trip opens the motor starter when the control voltage drops below the tripping

threshold of 0.35–0.7 times the rated voltage. For the starter contacts to be closed again, the control

voltage must be above 0.85 times the rated voltage. The GV7AU undervoltage trip meets the

requirements of IEC 60947-2. For location of the undervoltage trip unit, see page 18.

Shunt Trip GV7AS

The shunt trip opens the motor starter when the control voltage rises above 0.7 times the rated voltage.

For location of the shunt trip unit, see page 18.

Operation (GV7AU or GV7AS)

When the motor starter has been tripped by a GV7AU or AS trip, it must be reset either locally or by

remote control. (For remote control, please consult your Square D Regional Sales Office).

Tripping has priority over manual closing. If a tripping instruction is present, manual action does not

result in the closing of the contacts even temporarily.

Both the undervoltage trip and shunt trip have a durability of 50% of the mechanical life of the motor

starter.
