The Schneider Electric GV2ME16K2BW3 is a DOL reversing combination starter from the TeSys GV2-ME series — a single assembly that integrates a 3-pole reversing contactor, a combination block (GV2AF01), and a motor circuit breaker (GV2ME) into one DIN-rail-mounted unit. The thermal protection adjustment range covers 9...14 A, and the control circuit runs on 24 V DC. It is rated for AC-3 duty (motor switching) and delivers 5.5 kW at 400/415 V AC, 5.5 kW at 440 V, and 7.5 kW at 500 V.
The AC-3 utilisation category tells you this starter is built for switching squirrel-cage motors — making and breaking stalled-rotor currents during starting, and handling the lower running current during normal operation. The 9...14 A thermal adjustment range sets the overload relay's trip threshold; you dial it to match the motor's full-load current. Magnetic tripping is fixed at 170 A, so short-circuit protection clears fast without waiting for the thermal element. Breaking capacity is 15 kA at 400/415 V AC per IEC 60947-4-1, dropping to 8 kA at 440 V and 6 kA at 500 V. Coordination is Type 1 — after a fault the starter may need component replacement, but the breaker clears the fault without welding main contacts. This is standard for panel designs where downstream protection is sized to limit let-through energy.
This is a reversing starter — two contactors mechanically and electrically interlocked to swap two phases for motor reversal. The 24 V DC coil is common in PLC-controlled lines where the control voltage matches the I/O rack supply. No separate overload relay or contactor assembly to wire — the combination block handles the interlock and power bus.
