Schneider Electric GV3-M10 Motor Protection Circuit Breaker

Schneider Electric's TeSys GV3-M10 Motor Protection Circuit Breaker is a 3-pole, thermal-magnetic device that protects and manually switches three-phase motors in industrial environments, commonly installed in motor control centers, conveyors, pumps, compressors, and fans. It accepts a current range of 4–6 A (adjustable thermal setting) with a rated thermal current of 10 A, and operates at 600 VAC (UL/CSA) or 690 VAC (IEC) with a network frequency of 50/60 Hz. The GV3-M10 provides motor protection with up to 100 kA breaking capacity (application dependent) and supports motor power ratings of 2.2 kW at 400/415 V, 3 kW at 500 V, and 4 kW at 660/690 V; it features screw clamp terminals and can be mounted on a DIN rail or panel, with phase failure sensitivity and push-button control. Common replacements include Schneider Electric GV3P10, Siemens 3RV2021, and Eaton PKZM4-6.3, reflecting its role in repair, retrofit, and industrial automation maintenance.
