Eaton DILM40 3-Pole Contactor, 230 V 50 Hz / 240 V 60 Hz Coil, 18.5 kW AC-3 400 V, 1NO+1NC

Panel builders and maintenance technicians in motor control centers, HVAC systems, and pump stations rely on the Eaton DILM40 contactor for dependable switching of three-phase motors up to 18.5 kW at 400 V AC-3. Its coil accepts 230 V at 50 Hz or 240 V at 60 Hz, making it suitable for both European and North American control circuits. The 3-pole main contacts handle 40 A AC-3, while one normally open and one normally closed auxiliary contact provide status feedback or interlocking. Screw terminals and DIN rail or screw mounting simplify installation.
