The EATON DILM25-10 (RDC24) is a high-performance 3-pole magnetic contactor from the xStart series. It is specifically designed for switching motors and inductive loads in demanding industrial environments.
The RDC24 suffix is critical—it indicates that the contactor is equipped with an electronically controlled DC coil (24V DC), which offers significantly lower power consumption and a wider voltage tolerance than standard AC or DC coils.
Part Number: 277146
Number of Poles: 3 Main Contacts (NO)
Auxiliary Contacts: 1 NO (Built-in)
Coil Voltage: 24V DC (RDC24 range: 24–27V DC)
Rated Operational Current (Ie ): * AC-3 (Motor Load): 25 A (up to 400V)
AC-1 (Resistive Load): 45 A (at 40°C)
Motor Rating: 11 kW at 400V / 15 HP at 480V.
Terminal Type: Screw terminals.
Protection: IP20 (Finger and back-of-hand proof).
Most standard DC contactors require a high "pick-up" current to close the contacts. The RDC24 version uses an integrated electronic circuit to manage this:
Low Holding Power: Only consumes about 0.5W while closed, reducing heat in the control cabinet.
Wide Voltage Range: Operates reliably even if your 24V supply fluctuates.
Integrated Suppressor: Includes built-in varistor protection to prevent voltage spikes when the coil is de-energized, protecting your PLC outputs without needing external flyback diodes.

Meta Description: Shop the Eaton DILM25-10 (RDC24). 25A 3-pole contactor with 24V DC electronic coil and 1 NO auxiliary contact. Reliable 11kW motor control for industrial automation.
Product Overview: The Eaton DILM25-10 (RDC24) is a robust, compact solution for switching motors up to 11 kW. As part of the Moeller series, this contactor is engineered for millions of operations. Its RDC24 electronic coil provides superior energy efficiency and allows for direct control from PLC transistor outputs without the need for interposing relays.
Key Features:
Efficient Control: Electronic DC coil minimizes power loss and heat.
Compact Design: Identical dimensions for AC and DC operated devices simplifies panel layout.
Safety First: Positive-guided contacts and "mirror contact" status ensure reliable feedback for safety circuits.
Global Compliance: UL, CSA, IEC/EN 60947, and CE certified for worldwide use.
Typical Applications
Three-phase motor starting (Direct-on-Line).
Heating and lighting circuit control.
Conveyor systems and industrial pumps.
Automation panels requiring low-wattage DC control components.
Auxiliary Contact Blocks: DILA-XHI or DILM32-XHI (Top or Side mount).
Overload Relays: Pair with ZB32 series for full thermal motor protection.
Mechanical Interlocks: DILM32-XMV (for reversing starter configurations).
