The Schneider Electric GV3D02 is a shunt trip release (MX) from the TeSys GV3 range, designed to remotely trip a circuit breaker or motor starter via a control signal. It is a service part, sold in a set of 10 units. The release operates with a control circuit voltage of 110 V AC at 50 Hz, 120 V AC at 50/60 Hz, or 127 V AC at 50/60 Hz, with an operating range of 0.8 to 1.1 times the nominal voltage (Un). The threshold tripping voltage is 0.7 to 0.35 Un. Rated insulation voltage (Ui) is 690 V AC per IEC 60947-1, and 600 V AC per UL 60947-4-1 and CSA C22.2 No 60947-4-1, meaning it is suitable for use in panels with those voltage ratings.
The release connects via screw clamp terminals accepting 0.75 to 2.5 mm² flexible or solid wire, with a tightening torque of 1.2 N·m. It draws 7 W inrush (12 VA AC) and holds at 2.5 W (7 VA AC), so the control transformer must be sized to handle the inrush without voltage sag. Mechanical durability is rated at 15,000 cycles, and the operating time is 15 ms per IEC 60947-1. The on-load factor is 100%, meaning it can be continuously energized in the hold state.
