White-Rodgers 124-317111 Coil

The White-Rodgers 124-317111 is a heavy-duty SPDT 36VDC continuous duty solenoid engineered for high-current switching applications in industrial and mobile equipment. Featuring an isolated coil design, this contactor provides reliable circuit isolation, making it a critical component for electric vehicle DC controls and material handling equipment. The 124 series construction handles a normally open contact rating of 100 Amps continuous with a massive 400 Amp inrush capacity, while the normally closed side supports 50 Amps continuous and 100 Amps inrush. This 36-volt DC magnetic contactor is built for longevity in demanding environments, ensuring stable power delivery without the coil degradation common in intermittent duty substitutes. For technicians performing solenoid replacement, the bracket-mounted housing and standard terminal configuration allow for efficient installation. Integrating this heavy-duty DC relay into your system ensures precision switching and robust thermal management for industrial power systems requiring persistent performance.

• High-Amperage Capacity: Manages 100A continuous current and up to 400A inrush on the normally open circuit for heavy load start-ups.
• Continuous Duty Rating: Designed for constant energized states without overheating, ideal for 36V battery systems.
• Isolated Coil Design: Provides enhanced safety and electrical separation between the control and load circuits.
• SPDT Configuration: Versatile Form C contacts allow for complex switching logic in HVACR and industrial controls.
• Rugged Metal Housing: Encased in a durable shell to withstand vibration and environmental stress in field applications.

Common Technical Questions

Can this solenoid be used for intermittent tasks?
Yes, while it is rated for continuous duty, the 124-317111 performs reliably in intermittent applications; however, intermittent-rated solenoids cannot replace continuous-duty models without risking coil failure.

How do I wire the isolated coil terminals?
Unlike grounded solenoids, the isolated coil 36VDC terminal requires a dedicated ground wire to the coil circuit, which prevents electrical noise from interfering with the chassis.

Is this compatible with 48V systems?
No, this unit is specifically rated for 36VDC input. Operating at higher voltages will result in excessive heat and eventual coil burnout.
