DC POWER

CONTACTORS – SPNO

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.

WARNING – FIRE HAZARD

Must be installed in a dry and protected

place. Failure to protect solenoid from water

and other contaminants could result in Fire,

Property Damage, Serious Personal Injury,

or Death.
