The Telemecanique GV2 AU385 is a voltage trip — essentially an undervoltage or overvoltage release for the GV2 motor-protection range. When the control voltage on the [Uc] circuit (380…400 V AC 50 Hz) drops outside the 0.85…1.1 Un limits, it trips the connected GV2 breaker, killing power to the motor. That's your protection against a brownout cooking the windings or a voltage spike damaging the contactor coil.

Frequently asked questions
What is GV2 AU385 used for?
It's a voltage trip used with GV2 motor circuit breakers. It monitors the control voltage (380-400 V AC 50 Hz) and trips the breaker if the voltage goes outside the 0.85-1.1 Un window, protecting the motor from undervoltage or overvoltage conditions.
Where can I buy GV2 AU385?
We source the GV2 AU385 to order against an RFQ through independent distribution. Send a request and we'll confirm availability and current pricing at quote time.
What is GV2 AU385's rated insulation voltage?
The rated insulation voltage [Ui] is 690 V AC, so it's rated for use in 400 V three-phase panels and similar industrial control circuits.
