A SPDT 10 ampere contact set alternates continuously as long as power is applied to the relay. Typical applications include OFF/ON cycling for equipment burn-in test, lighting controls, and automatic cycling of electrically operated devices. Contact Information: 1 form C (SPDT) contact set. 1/2 HP 240 VAC, 1/3 HP 125 VAC. 10 amperes maximum 30 VDC or 250 VAC. Minimum switching load current 10 ma 5 VDC. Timing Specifications: OFF/ON recycling (flasher) timer. Standard timing ranges are shown below. Custom and fixed timing are available consult factory. Timing ranges: A: .25 to 10 seconds G: 1 to 4 hours B: .25 to 25 seconds H: 14.4 minutes to 24 hours Amperite Co. 567 52nd Street P.O.
