It combines a GV2ME motor circuit breaker, a GV2AF3 combination block, and a 3-pole reversing contactor in one DIN-rail-mounted unit. The thermal protection adjustment range is 0.63 to 1 A, sized for motors drawing 0.25 kW at 400/415 V AC or 0.37 kW at 440 V AC (50/60 Hz). The control circuit runs on 24 V DC.
Rated for AC-3 utilisation category — the standard for squirrel-cage motor switching — so the 0.63-1 A thermal range directly governs the motor full-load current you can protect. The magnetic trip is fixed at 13 A, providing short-circuit protection above the thermal band. Breaking capacity is 50 kA at 400/415 V and 440 V per IEC 60947-4-1, meaning it can safely interrupt a fault current up to that level without upstream fuses needing to clear first. Type 1 coordination means the starter remains operational after a short circuit but may need contact replacement — typical for panel designs where downtime for swap-out is acceptable.
Mounts on standard DIN rail. Dimensions are 90 mm wide, 176.4 mm high, 99.6 mm deep — the width is the critical fill factor on a crowded rail; the depth leaves clearance for wiring ducts and gland plates.
