This SPST-NO electromechanical relay has a contact arrangement of single pole single throw normally open and a contact form of 1 form A. It can handle a DC coil voltage of 24 volts and a coil current of 36.36 milliamps with a coil resistance of 660 ohms. The relay has a maximum pick-up voltage of 18 volts DC and a minimum dropout voltage of 2.4 volts DC. It can switch a maximum AC switching voltage of 277 volts and a maximum DC switching voltage of 28 volts, with a maximum switching current of 40 amps and a maximum switching power of 1.2 kilowatts or 11.08 kilovolt-amperes. The relay is designed for through hole mounting and has a termination style of PC pin with 4 number of terminals. It has a non-latching relay construction and an operate time of 15 milliseconds. The relay does not have a coil suppression diode or a push to test button. It can operate within a temperature range of -55 to 85 degrees Celsius.
