This is a 220-volt relay. I had planned to use it for a 120-volt project, figuring that if it's designed to switch 30 amps at 220 volts, it could easily handle any 120-volt current I have available. The coil resistance is 6.6 megohms. Both normally open switches are open. The coil is rated for 208-240 VAC. 120 volts is not enough to close the switches. I would test it at higher voltages, but my workshop isn't wired for 220.
