- Intermittent Duty Cycle = 30 seconds “ON” maximum and 6 minutes “OFF”
- “4” = Isolated Coil
- Coil resistance in Ohms @ 25°C
- Inrush Current: Current applied within the first 1/2 second of contact closure
- Coil grounded to bracket
NOTE: CAUTION must be used in coil selection for use in 12 volt systems where battery charging may expose coil to continuous, higher-than-rated voltage. 14 volt coils are recommended. White-Rodgers will not be responsible for consequences of misapplied solenoids.
