The GV2ME16K2F7 is a DOL reversing combination starter from the TeSys GV2-ME range. It's a single block that combines a motor circuit breaker (set for 9...14 A thermal protection) and a 3-pole reversing contactor with a 110 V AC 50/60 Hz coil. The built-in magnetic trip is set at 170 A, so it catches a locked-rotor fault fast. Rated for AC-3 duty (squirrel-cage motors), it handles up to 5.5 kW at 400/415 V, and can go to 7.5 kW at 500 V. The breaking capacity is 15 kA at 400/415 V per IEC 60947-4-1, which covers most industrial panel fault currents without needing an upstream fuse or breaker to do the heavy lifting. The GV2AF01 auxiliary contact block is included in the assembly, so you get a built-in signal contact for the PLC or status lamp without ordering extra parts.
The 9...14 A thermal adjustment range is what you set to match the motor's full-load amps. For a 5.5 kW motor at 400 V, you'd dial it in around 11-12 A. The 170 A magnetic trip is fixed — it's there for short-circuit protection, not overload, so you don't adjust it. That combination gives Type 1 coordination: under a fault, the starter might need contact replacement, but the downstream motor and upstream breaker stay intact. The reversing contactor pair means you get forward and reverse in one package, with mechanical interlocking built in. No risk of both contactors pulling in at once and shorting the phases. For a conveyor or hoist application, that's the difference between a controlled reversal and a bang.
