It is rated for 55 kW at 500 V and delivers 80 A in AC-4 duty at 400 V, which covers demanding reversing and inching applications where the contactor makes and breaks the motor current under load. Mounting is straightforward: it snaps onto standard 35 mm or 75 mm DIN rails and can be screw-fastened for vibration-prone environments.
The headline motor rating of 55 kW at 500 V tells you this contactor handles a 55 kW induction motor on a 500 V line — common in European 500 V industrial networks. The mechanical life of 10 million operations means the coil and armature outlast several contact tip changes in high-cycle applications. The control coil operates at 50 Hz with a pick-up voltage range of 0.8 to 1.1 times the rated value, and the arcing time sits between 10 and 15 ms. That arcing window is short enough to coordinate with upstream fuses or circuit breakers without nuisance tripping.
