The Schneider Electric GV2ME08K1B7 is a non-reversing DOL combination starter from the TeSys GV2-ME series, integrating a motor circuit breaker, a 3-pole contactor, and a combination block (GV2AF01) into one compact unit. It provides thermal and magnetic motor protection with an adjustable thermal range of 2.5...4 A and a fixed magnetic tripping current of 51 A, sized for AC-3 motor duty. The control circuit is rated for 24 V AC at 50/60 Hz, and the starter is rated for motor power up to 1.5 kW at 400/415 V AC and 2.2 kW at 500 V AC, making it suitable for small three-phase induction motors on pumps, conveyors, or fans in industrial control panels.
The 50 kA breaking capacity at 400/415 V AC, conforming to IEC 60947-4-1, means this starter can safely interrupt fault currents up to 50 kA without welding its contacts or cascading failure upstream — critical for installations with high available fault current, such as near a transformer secondary. The Type 1 coordination means that after a short-circuit fault, the contactor may need replacement, but the motor starter itself is protected. This is standard for most motor control centers where the contactor is a serviceable item.
