It is a non-reversing starter rated for AC-3 utilisation category, meaning it is built for starting and stopping squirrel-cage induction motors under load — the standard duty for conveyors, pumps, and fans in industrial control panels. The thermal protection adjustment range spans 1.6 to 2.5 A, so it is sized for small motors — for example, a 0.75 kW motor on a 400/415 V supply. The magnetic trip is fixed at 33.5 A, providing short-circuit protection that clears fast without nuisance tripping on normal inrush. Breaking capacity is 50 kA at 400/415 V AC, certified to IEC 60947-4-1. Coordination is Type 1, so after a fault the starter may need contact replacement, but the upstream protection stays intact.
The device composition includes one GV2AF01 combination block and a GV2ME motor circuit breaker, so if you are retrofitting an existing panel, verify the auxiliary block and contactor match the original assembly.
The 45 mm width occupies two 22.5 mm modular slots, so plan your enclosure fill factor accordingly. The depth of 87 mm includes the overhang of the coil terminals; leave clearance for wiring and a screwdriver above and below the block.
