Schneider Electric GVAU207

The MN undervoltage release is specifically engineered for use with TeSys GV motor circuit breakers, including models GV2 and GV3. It operates within a control voltage range of 200V AC at 50Hz and can also accommodate 200-220V AC at 60Hz. The device is designed to trip the circuit breaker when the control voltage drops below 0.35 times the nominal voltage (Uc), with an opening range between 0.35 and 0.7 Uc.

Closing of the circuit breaker is only feasible when the control voltage is restored to between 0.85 and 1.1 Uc. This unit is mounted on the right-hand side of the circuit breaker and features screw clamp terminals for connection. Its multi-standard certifications, including IEC, UL, and CSA, ensure compliance with various international safety standards. The product also meets Green Premium compliance, indicating adherence to environmental regulations such as RoHS and REACh.

With a mechanical durability rating of 10,000 cycles for GV3 models and up to 30,000 cycles for GV2 models, this component ensures longevity in demanding applications. The device has a net weight of 0.105 kg and dimensions of 89 mm in height, 18 mm in width, and 66 mm in depth. It is designed for easy installation with a tightening torque requirement of less than 1.4 N.m.
