It integrates a GV2ME motor circuit breaker, a 3-pole contactor, and a GV2AF3 combination block into a single, pre-assembled unit for non-reversing motor control. The thermal protection adjustment range is 1.6...2.5 A, and the magnetic trip is fixed at 33.5 A. Rated breaking capacity is 50 kA at 400/415 V, 440 V, and 500 V, conforming to IEC 60947-4-1 for Type 1 coordination.
Its footprint is 45 mm wide, 176.4 mm tall, and 99.6 mm deep — a compact 3-pole block that fits a standard motor control center bucket or panel enclosure. It is a DOL combination starter, so it handles the motor circuit breaker, contactor, and control wiring in one assembly. For a commissioning engineer, this means fewer interconnections to wire and test compared to a separate breaker-and-contactor build.
