White-Rodgers 124-114111 Solenoid

The White-Rodgers 124-114111 Solenoid is a heavy-duty, industrial-grade solution designed for high-current switching in demanding HVACR and mobile environments. Engineered with a SPNO (Single Pole Normally Open) configuration and an isolated 24VDC coil, this 124 SERIES contactor is built for continuous duty, handling 100 Amps of continuous current and a robust 400 Amp inrush capactity. The steel enclosure and silver alloy contacts ensure dependable low-voltage drop across the contacts while maintaining superior arc resistance and electrical longevity. With a temperature rating spanning from -40°F to 149°F, this power relay is ideal for remote power distribution in emergency vehicles, golf carts, and large-scale industrial automation systems. The design features standard bracket mounting and requires a vertical orientation with terminals up for optimal performance. Techs should note the 53-ohm coil resistance and verify the 24VDC system compatibility to prevent premature coil failure or overheating during extended operation cycles.

• Continuous 100A Rating: Designed to maintain high-current loads without thermal breakdown, essential for pump and winch control.
• Silver Alloy Contacts: Provides superior conductivity and prevents sticking or pitting under 400A inrush conditions.
• Isolated Coil Design: Minimizes electrical noise and prevents unwanted ground loops in sensitive control circuits.
• Rugged Steel Housing: Offers high dielectric strength (600V) and protects internal components from harsh job site debris.
• Standardized Fastening: Features 5/16"-24 UNF-2A contact terminals and #10-32 UNF-2A coil terminals for secure high-torque connections.

Is the 124-114111 suitable for intermittent duty if the cycle is fast?
While this unit is optimized for continuous duty, it can handle rapid cycling; however, ensure the coil is not subjected to voltage spikes exceeding 110% of the nominal 24VDC rating to preserve the silver alloy contact life.

What is the recommended mounting alignment?
For maximum reliability, mount the solenoid in a vertical plane with the coil terminals facing upward. This orientation ensures proper heat dissipation and mechanical operation of the internal plunger.

Can I use this for 12VDC applications?
No. The 24VDC isolated coil requires a specific voltage range to pull in the contacts properly. Using a 12V source will result in insufficient holding force and potential contact welding.
