Under / Over voltage sensing relay incorporating 219 series internal components coupled with an electronic module. Pull-in voltage is adjustable from 85 to 135VAC for frequencies ranging from 50 to 400 hertz. Hysteresis is typically set for a 4 volt differential but can be user adjustable from 3 to 14 volts when external connections are available.

Additional contact configurations and coil options are available – please use the RFQ/RFI tab above to submit your request.

Made in U.S.A.
