Eaton DILM25-32 3-Pole Power Contactor, 230 V AC Coil, 11 kW, 25 A, 3NO + 2NO/2NC Auxiliary 277228

Industrial motor control demands a contactor that can switch high currents reliably while withstanding harsh electrical environments. The Eaton DILM25-32 power contactor addresses this by offering robust switching for three-phase motors up to 11 kW at 400 V AC, with a 230 V AC coil and a versatile auxiliary contact set for control and feedback.

Who is it for

This contactor is built for panel builders, machine OEMs, and maintenance engineers who need a compact, DIN-rail mountable switching device for motor starters, heating circuits, and other industrial loads. It suits applications where space is limited but performance cannot be compromised.

Main features

• 3 main poles, normally open (3 NO), rated for 25 A AC-3 at 400 V (11 kW motor power).
• Integrated auxiliary contacts: 2 NO + 2 NC for control logic, interlocks, or status indication.
• 230 V AC coil, 50/60 Hz, with a wide operating temperature range from -25 to +60 °C.
• High electrical durability: 1.5 million operations under AC-3 load; mechanical life of 10 million cycles.
• Rated insulation voltage 690 V and impulse withstand 6 kV for safe operation in industrial networks.
• Mounts on standard 35 mm DIN rail or with screws; IP20 protection for use inside enclosures.
