Eaton Moeller DILM17 High-Current power Contactor

The Eaton Moeller DILM17 is a high-performance, 3-pole power contactor belonging to the renowned xStart C series. Designed for global industrial applications, this contactor is engineered to deliver reliable switching performance for motor control and power distribution. With a compact frame size (FS2) and high current capability, the DILM17 series is the ideal solution for OEMs, panel builders, and facility maintenance professionals seeking a balance between durability and energy efficiency.

Key Features & Benefits

High Current Rating: Rated operational current of 18 A (AC-3) at 400 V, capable of handling motors up to 7.5 kW at 400V, with a conventional thermal current (Ith) of up to 40 A for AC-1 applications.

Compact & Space-Saving: The DILM17 occupies a compact footprint (45 mm width, 85 mm height), allowing for high-density panel layouts without compromising on performance .

Global Certifications: Fully compliant with IEC/EN 60947-4-1, UL, and CSA standards, making it suitable for both North American and international markets.

Dual-Frequency Coils: AC-operated models feature dual-frequency coils (50/60 Hz), reducing inventory complexity by allowing one device to work across different regional power grids.

Energy Efficient: Extremely low pickup and holding power consumption reduces heat dissipation in control panels (as low as 7.1 VA holding at 50 Hz), contributing to lower energy costs.

Integrated Auxiliary Contacts: Available in various configurations including 1 NO (DILM17-10) or 1 NC (DILM17-01) built-in auxiliary contacts, with options for additional add-on blocks.

Why Choose Eaton Moeller DILM17?

The DILM17 is part of the globally recognized Moeller series (now under Eaton), known for its "mirror contact" safety feature and robust construction. Unlike standard contactors, the DILM17 series maintains the same compact dimensions whether using AC or DC coils, offering seamless flexibility for designers. Its high short-circuit rating and coordination with Eaton Moeller circuit breakers (Type 1 and Type 2 coordination) ensure system protection and reduce downtime.

Buyers Guide

When selecting the DILM17 for your panel, verify the coil voltage (e.g., 24VDC, 230VAC) and auxiliary contact configuration (NO vs. NC) to match your control circuit requirements. If you are replacing an old Moeller unit, check the article number (e.g., 277038, 277002, 277050) to ensure a perfect fit.
