Product Description

The WHITE-RODGERS DC Contactor (MPN 124-903) is a 100 A rated, SPST-NO, continuous-duty DC power solenoid with a 24 V DC coil. It features 4 terminals, #10-32 coil termination, and 5/16 in-24 contact termination.

Frequently Asked Questions

What is the WHITE-RODGERS 124-903 DC contactor used for?

The WHITE-RODGERS 124-903 is a 100 A, SPST-NO DC power solenoid used to switch high-current DC loads in industrial control panels, battery systems, and motor circuits. Its continuous-duty coil allows sustained engagement without overheating, making it suitable for applications requiring reliable, long-duration power switching.

What are the specifications of the WHITE-RODGERS 124-903 DC contactor?

The WHITE-RODGERS 124-903 is a 100 A rated, SPST-NO contactor with a 24 V DC coil. It has 4 terminals, #10-32 coil termination, and 5/16 in-24 contact termination. The duty cycle is continuous, and the contact form is single-pole, single-throw normally open.

Where to buy the WHITE-RODGERS 124-903 DC contactor worldwide?

3G Electric supplies the WHITE-RODGERS 124-903 DC contactor to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this 100 A, 24 V DC continuous-duty contactor.

How to select a DC contactor for continuous-duty applications?

For continuous-duty applications like the WHITE-RODGERS 124-903, ensure the contactor's coil voltage matches your control circuit (24 V DC here) and the current rating exceeds your load (100 A). Verify the contact form (SPST-NO) and termination sizes (#10-32 coil, 5/16 in-24 contacts) fit your wiring. Always consult the manufacturer's data sheet for thermal limits.
