TemperatureRange

–– -40˚F to 150˚F

Terminations

–– Contacts: 5/16"-24 UNF-2A thread

–– Coil: #10-32 UNF-2A thread

Recommendedmounting

–– Vertical plane with coil terminals up.

* Terminal Type: “3” = Grounded Coil, SPNO

“4” = Isolated Coil, SPNO

“6” = Isolated Coil, SPDT

** Inrush Current: Current applied within the first 1/2 second of contact closure

hardwareTorquespecification

–– Contact Terminal: 60 inch-lbs., max.

–– Coil Terminal: 12-18 inch lbs.

–– caution:Aback-upwrenchmustbeusedtoholdthebottom
