The Schneider Electric GV2ME08K2B7 is a fully assembled reversing combination starter from the TeSys GV2-ME line. It integrates a GV2ME motor circuit breaker, a 3-pole reversing contactor pair, and a GV2AF01 mechanical interlock block into one DIN-rail-mountable unit. The thermal protection adjustment range is 2.5...4 A, and the control circuit runs on 24 V AC 50/60 Hz. This is a DOL (direct-on-line) reversing starter — it handles forward/reverse control of a three-phase motor without a separate reversing contactor assembly. The AC-3 utilization category means it is rated for switching squirrel-cage motors during starting, stopping, and reversing under load.
The thermal protection setting of 2.5...4 A governs the overload trip point. For a motor drawing its full-load current within that band, the bimetallic element tracks the heating curve. The magnetic trip is fixed at 51 A — that is the instantaneous short-circuit pickup, roughly 13× to 20× the thermal setting, which avoids nuisance tripping on motor inrush while still catching a phase-to-phase fault. Motor power ratings vary by supply voltage: 1.1 kW at 400/415 V, 1.5 kW at 440 V, and 2.2 kW at 500 V. On a 400 V line, this starter covers a 1.1 kW reversing motor load. The coordination type is Type 1 — meaning the starter itself may need replacement after a short-circuit fault, but the downstream contactor and the rest of the panel remain serviceable. Mechanical footprint: 45 mm wide, 152 mm tall, 87 mm deep. That is a standard three-module DIN-rail width.
