A double pole relay makes and breaks both hot legs of a 208- 240 VAC 20 Amp circuit. The relay operates on 24 VDC which is generated internally. The device is activated by closing a single pole dry contact closure connected to the terminal block which completes the low voltage DC circuit through the relay coil. Control circuit current flow is about 70 mA. A green power on LED illuminates when the ROK2 is turned on.
