WHITE RODGERS (EMERSON ELEC)
WHITE RODGERS (EMERSON ELEC) 120-106131 Solenoid hvac control
12 V DC solenoid with SPNO contacts rated 80 A continuous and 400 A inrush, intermittent duty, water and dust resistant from -20 °F to 150 °F
- 12 VDC isolated coil for reliable HVAC switching
- SPNO contact design handles 80 A continuous duty
- 400 A inrush capacity manages heavy start-up loads
- Intermittent duty cycle suits on-demand system operation
- Water and dust resistant from -20 to +150 °F
Application fit
The 12 VDC isolated coil suits 12 volt automotive or mobile equipment electrical systems. Intermittent duty cycling means the solenoid is designed for on-off operation rather than continuous energisation. The standard bracket allows direct mounting to a flat surface without additional hardware.
Upgrade path
This unit replaces a failed or worn 120-106131 solenoid in existing HVAC control circuits. The 80 amp continuous and 400 amp inrush ratings match the original specification, restoring reliable clutch or valve actuation. The jump is worth it when the old coil shows voltage drop, contact welding or water ingress.

Questions about this item
How long can the 120-106131 solenoid stay energised before the intermittent-duty coil overheats?
The coil is rated for intermittent duty only; it must be de-energised regularly to prevent overheating during sustained use.
How much heat does the solenoid generate when it switches 80 amps continuously for hours?
The contact rating is 80 amps continuous, but the coil is intermittent duty so extended operation will raise coil temperature; the housing is rated to 150 °F ambient.
What voltage source and wiring does the 120-106131 require to operate?
A 12 V DC supply is needed for the isolated coil, plus power cables rated for at least 80 amps continuous and 400 amps inrush on the main contacts.
