White-Rodgers 70-117224 Solenoid

The White-Rodgers 70-117224 Solenoid is a heavy-duty 24VDC continuous duty contactor engineered for high-current DC power applications. Designed with an SPNO (Single Pole Normally Open) configuration, this unit features an isolated coil to prevent electrical interference and ensure reliable switching in demanding environments. Field technicians value the 70-117224 for its robust 50 amp continuous contact rating and its ability to handle steady-state loads without excessive heat rise. The housing is integrated with a dust-resistant case and standard mounting brackets for straightforward vertical installation in industrial or mobile HVACR equipment. With a temperature rating spanning -40°F to 149°F (-40°C to 65°C) and a coil resistance of approximately 60.4 ohms, this DC power solenoid provides stable performance even during long-duration cycles. Whether you are replacing a failed contactor in a specialized heating system or integrating high-current control into a new build, this White-Rodgers 70 Series component delivers the precision and mechanical longevity required for professional-grade power management.

• Continuous Duty Rating: Optimized for systems where the solenoid remains energized for extended periods without coil fatigue.
• High Current Capacity: Rated for a 50 amp continuous load, providing ample overhead for heavy-duty DC circuits.
• Isolated Coil Design: The isolated coil and case prevent grounding issues and electrical noise in sensitive control circuits.
• Rugged Construction: A dust-resistant case protects internal copper contacts from environmental contaminants and debris.
• Flexible Mounting: Features a standard bracket and 5/16-24 UNF-2A terminals for secure, high-torque electrical connections.

Is the coil grounded to the case?
No, the 70-117224 is an isolated coil model, meaning the coil terminals are not internally connected to the solenoid housing, allowing for more versatile wiring configurations.

What is the recommended mounting orientation?
For optimal performance and to ensure the plunger operates correctly, this DC power contactor should be mounted vertically with the cap facing downward.

Can this be used for intermittent duty applications?
While designed for continuous duty, this solenoid can handle intermittent cycles; however, its primary engineering focus is on sustained energization without overheating.
