The GV2DP203B7 is a reversing motor starter combination from the TeSys Deca range, built as a single assembly that includes a three-pole reversing contactor, a GV2AF3 combination block, and a GV2P motor circuit breaker. It is rated for AC-3 utilisation category — the standard for squirrel-cage motor switching — with a thermal protection adjustment range of 0.25…0.4 A and a magnetic tripping current of 5 A.
The unit delivers an Iq rated breaking capacity of 130 kA at 400/415 V, 440 V, and 500 V, conforming to IEC 60947-4-1. Coordination is Type 2, meaning that under short-circuit conditions the starter remains serviceable — no component replacement required after clearing a fault within its rating. For a motor starter this small (0.09 kW at 400 V), 130 kA is a generous margin; it lets the part sit on a high-fault bus without needing upstream current-limiting fuses.
The assembly measures 90 mm wide, 176.4 mm high, and 105.6 mm deep. It mounts on DIN rail as a single compact block — no separate wiring between the contactor and breaker sections. The 24 V AC coil keeps control transformer sizing straightforward; verify the control transformer VA rating covers the inrush of both contactors in the reversing pair.
