Power contactor, I=40A (AC-3) DILM40(RDC24) 277780

Power contactor – reliable control of motors and loads

This three-pole power contactor DILM40(RDC24) from Eaton Electric is a robust solution for frequent switching of motors and other AC-3 loads. Designed to operate in a wide voltage range (230…690V AC), it ensures reliable operation in demanding industrial conditions. The rated operating current of 40A at 400V allows handling loads up to 18.5 kW, making it an ideal choice for various applications.

Design and application

The contactor features screw connections, which guarantee a secure and durable connection of wires of various cross-sections. The DC coil (24…27V) with a built-in protection circuit minimizes energy consumption and ensures a long service life. Thanks to its compact dimensions (115 x 55 x 132.1 mm), the contactor easily integrates with existing installations. The ability to mount additional auxiliary modules expands the functionality of the device, adapting it to specific application needs.

Advantages and benefits for professionals and users

• Versatility: Designed for controlling both AC motors and other loads, reducing the need to have many different devices.
• Safety: Built-in overvoltage protection in the DC coil protects against damage caused by voltage surges.
• Easy installation: Screw connections allow for quick and secure connection of wires, reducing installation time.
• Modularity: The ability to expand with additional auxiliary modules increases the flexibility and functionality of the contactor.
• Durability: Solid construction and high-quality materials ensure a long service life even in harsh working conditions.
• Common accessories: Identical dimensions of AC and DC contactors allow the use of the same mounting accessories, simplifying inventory management.
• High efficiency: Rated power of 18.5 kW at 400V ensures efficient control even of demanding loads.
• Compliance with standards: Contactors of the DILM series have marine approvals, confirming their high quality and reliability in specific operating conditions.

Additional information: the rated operating current for AC-1 is 60A at 400V, and for AC-4 – 18A, allowing the contactor to be adapted to different types of loads. The rated power for AC-4 at 400V is 9kW, and NEMA is 22kW – these parameters are important when designing electrical installations according to various standards.
