Copeland Comfort Control (White Rodgers) 124-105111 Solenoid

The White Rodgers 124-105111 is a robust 12VDC continuous duty solenoid engineered for heavy-duty power switching in HVACR and commercial applications. This Single Pole Normally Open (SPNO) relay features a high-current capacity designed to handle sustained electrical loads without coil degradation. Built with a rugged metal housing, it provides superior heat dissipation and mechanical durability compared to standard plastic alternatives. The isolated coil design allows for flexible wiring configurations, making it a reliable choice for 12V DC power systems, motor control, and battery isolation. Contractors often specify the 124-105111 solenoid for its consistent pull-in voltage and low contact resistance, ensuring minimal voltage drop across the circuit. Whether you are replacing a failed White Rodgers relay or integrating it into a custom control panel, this component delivers the industrial-grade switching performance required for mission-critical equipment longevity.

• Continuous Duty Cycle: Engineered to remain energized for extended periods without overheating or coil failure.
• SPNO Configuration: Single Pole Normally Open contacts ensure reliable circuit completion upon activation.
• Heavy-Duty Construction: Zinc-plated steel housing provides corrosion resistance and structural integrity in harsh environments.
• Flexible Mounting: Bracket design allows for secure installation in various orientations within control cabinets.
• High Amperage Capacity: Capable of managing high inrush currents typical of motor and compressor start-ups.

Is the 124-105111 suitable for intermittent or continuous applications?
This model is specifically rated for continuous duty, meaning it can handle being energized 100% of the time, unlike intermittent solenoids which will burn out if left active.

What is the difference between grounded and isolated coils?
The White Rodgers 124-105111 features an isolated coil, meaning the coil circuit is separate from the housing ground, allowing for more versatile wiring in complex DC systems.

Can this replace other 12V 4-terminal solenoids?
Yes, provided the amperage requirements and duty cycle match. Always verify the terminal configuration and mounting footprint before installation.
