Contactor 15kW/400V, 24VDC control DILM32-10-EA(RDC24) 189918

DC contactor for demanding applications

This three-pole Eaton DILM32-10-EA(RDC24) contactor is a robust solution for controlling DC loads. Designed to operate with a coil voltage of 24V DC, it allows for reliable switching of circuits with a rated current of 32A. This is particularly useful in systems where high inrush currents occur, as well as in applications requiring frequent switching.

Characteristics and application

This contactor is widely used in controlling DC motors, photovoltaic (PV) systems, energy storage systems and electric vehicles. Its construction with DC arc extinguishing chambers ensures a longer service life and increased safety, eliminating the risk of damage caused by arc formation during circuit disconnection. The 24V DC control voltage is ideal for collaboration with switch-mode power supplies, batteries and photovoltaic installations.

Advantages and benefits

• High switching capacity: The rated operating current AC-3 is 32A, and the rated power for AC-3 at 400V is 15 kW – enabling control of significant loads.
• Safety in DC applications: Special DC arc extinguishing chambers extend the service life of the contactor and minimize the risk of failure.
• Compact dimensions: Dimensions of 45 x 85 x 97 mm allow for easy integration with existing switchboards and control cabinets, thanks to standard mounting on a 35 mm DIN rail.
• Universal operating voltage: The ability to operate at both AC 50Hz and AC 60Hz in the range of 24V to 690V provides flexibility in various installations.
• Additional auxiliary contact: It has one normally closed (1Z) auxiliary contact, which can be used to signal the status of the contactor or to control other system elements.
• Solid construction: Made of high-quality materials guarantees durability and reliability even in harsh industrial conditions.
• Rated AC-1 current: The rated operating current Ie for AC-1 at 400 V is as high as 45 A, which expands the range of its applications.

Technical parameters in practice

The rated operating current for AC-4 at 400 V is 15 A, which means that this contactor copes well with loads characterized by high inrush currents – typical for electric motors. The rated power for AC-4 at 400 V is 7 kW. The rated control voltage Us for DC is in the range of 24V to 27V, which ensures compatibility with popular DC power sources.
