➀
Intermittent Duty Cycle = 30 seconds “ON” maximum and 6 minutes “OFF”
➁
“4” = Isolated Coil
➂
Coil resistance in Ohms @ 25°C
➃
Inrush Current: Current applied within the first 1/2 second of contact closure
➄
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.
