White Rodgers 70-111225 Contactor

The White Rodgers 70-111225 is a heavy-duty, 12VDC continuous duty solenoid designed for high-amperage switching in HVACR and industrial control circuits. Built with a Single Pole Normally Open (SPNO) configuration, this contactor features a rugged, dust-resistant case and a coil grounded directly to the frame for simplified installation in grounded systems. Rated for 80 Amps continuous current and up to 400 Amps inrush, it is engineered to handle the thermal demands of constant operation without coil failure or contact welding.

For technicians in the field, the 70-111225 contactor provides reliable execution in heating systems and DC power distribution. The 16-ohm coil resistance ensures efficient power consumption while maintaining a strong magnetic pull-in for the copper contacts. When replacing 12V solenoids, this unit is a preferred choice for its vertical mounting stability and standard bracket design. Its operating temperature range of -40°F to 149°F makes it a versatile solution for equipment located in unconditioned spaces or harsh mechanical rooms.

• High Current Capacity: rated for 80 Amps continuous duty to support heavy electrical loads.
• Environmental Protection: the dust-resistant housing prevents terminal pitting and debris buildup.
• Secure Terminals: features 5/16-24 contact studs for a high-torque, low-resistance connection.
• Optimized Coil Performance: grounded-to-case 12VDC coil simplifies wiring in mobile and industrial applications.

• Can I use this for intermittent starting applications? While rated for continuous duty, it can handle inrush cycles up to 400 Amps, making it highly durable for repeated switching.
• What mounting orientation is recommended? For peak performance and longevity of the internal spring mechanism, vertical mounting is the factory-recommended standard.
• How do I prevent coil burnout? Ensure the supply voltage is stable at 12VDC; excessively high voltage from charging systems can increase thermal stress on the coil.
