It integrates a 3-pole motor circuit breaker, a 3-pole reversing contactor, and a GV2AF01 combination block into a single assembly — one order code, one DIN-rail footprint at 45 mm wide, 152 mm tall, and 87 mm deep. The thermal protection adjustment range is 0.63 to 1 A, so this unit is sized for small motors in the 0.25 to 0.37 kW range at 400/415 V or 440 V AC, 50/60 Hz.
Rated AC-3 utilisation category means it is designed for starting and stopping squirrel-cage induction motors — the standard duty for a reversing starter on conveyors, pumps, or small hoists. The magnetic tripping current is set at 13 A, which provides short-circuit protection for the motor branch. Breaking capacity is 50 kA at 400/415 V and 440 V AC, conforming to IEC 60947-4-1; that high fault-current rating means this starter can be installed on panels with substantial upstream fault current without needing a separate current-limiting fuse ahead of it, as long as the coordination is Type 1 (the starter may need contact replacement after a fault, but the installation stays coordinated).
Control circuit and deployment context
The reversing configuration means two contactors are mechanically and electrically interlocked inside the combination block; the panel wiring connects the forward and reverse run commands separately.
