Eaton DILM9-10 24 V DC 3-Pole Power Contactor, 9 A AC-3, 4 kW, 1 NO Auxiliary Contact

Industrial motor control demands components that can handle frequent switching without compromising safety or longevity. The Eaton DILM9-10 power contactor is engineered to reliably start and stop three-phase motors up to 4 kW at 400 V AC-3, making it a cornerstone for machine builders and panel designers who need compact, dependable switching. Its 24 V DC coil allows direct integration into PLC-driven control circuits, eliminating the need for additional interposing relays.

Who is it for

This contactor is ideal for control panel builders, system integrators, and maintenance technicians working on industrial machinery, HVAC systems, conveyor lines, and pump controls. It suits applications where space is limited but performance cannot be compromised, and where standardized DIN rail mounting accelerates installation and replacement.

Main features

• 3-pole main contacts rated for 9 A at AC-3 (400 V), handling motors up to 4 kW.
• 24 V DC coil for direct control from PLC outputs or low-voltage control circuits.
• 1 built-in normally open (NO) auxiliary contact for status feedback or interlocking.
• Compact 45 mm width saves valuable rail space in crowded enclosures.
• Dual mounting: snap-on DIN rail or screw mounting for flexible panel layouts.
• High mechanical life of 10 million operations and electrical life of 1.5 million operations (AC-3) ensure long service intervals.
• IP20 finger-safe protection and screw terminals with captive screws for secure wiring.

Tips

When integrating the DILM9-10 into a control panel, ensure the coil supply is stable and within the 24 V DC tolerance to avoid contact chatter. For motor loads with high inrush currents, consider a higher-rated contactor or add a soft starter. Always verify the short-circuit protection coordination with the upstream circuit breaker according to IEC/EN 60947-4-1. For auxiliary contact expansion, Eaton offers front-mount auxiliary contact blocks that clip onto the contactor without tools.
