It is a\r\nreplacement part with 110 to 270 VAC pickup voltage. It has a safety time-out\r\nof 1 to 1.5 sec, at which point the contacts will open if the motor does not\r\nstart. It has universal, non-positional mounting and adapters for screw or\r\npush-on terminals. This adjustable potential relay replaces 3- and 5-terminal\r\npotential relays and is suitable for use with single phase motors or air\r\nconditioning and refrigeration compressors up to 5 hp.SpecificationsOperating\r\nvoltage110-270 VACLoad current30 ampTime setting range0.05 – 100 secOperating\r\ntemperature-40 to +150 degrees FDimensions1.5 x 2.25 x 1.75\" (H x W x D) H\r\nis height, the vertical distance from the lowest to highest point; W is width,\r\nthe horizontal distance from left to right; D is depth, the horizontal\r\ndistance from front to back. Relay switches (also called an electrical relay\r\nor an electrical relay switch) use a small amount of power to control a larger\r\nsource of power connected to electrical devices such as car motors, computers,\r\nand lighting installations. A basic relay switch has a control circuit with an\r\nelectromagnetic coil and a load circuit with contacts and a lever. When\r\ncurrent flows into the relay switch, it moves through the coil and a magnetic\r\nfield is created, which causes the lever in the load circuit to move between\r\ncontacts, either turning the device on or off. In a normally open (NO) relay\r\nswitch, when power is supplied to the relay, the load circuit is closed and\r\nthe power source connected to the relay is turned on. In a normally closed\r\n(NC) relay switch, when power is supplied to the relay, the load circuit is\r\nopen and the power source connected to the relay is turned off. In other types\r\nof relay switches, non-moving parts such as transistors or semiconductors can\r\nbe used as the control circuit to operate the switching mechanism. Relay\r\nswitches can be controlled with an external switch, such as a light switch, or\r\nthey can be connected to an automatically switched power source, such as a car\r\nignition. One relay can operate multiple switches, and multiple relays can be\r\noperated with a single switch, with each relay operating independently from\r\nthe other relays in the system. Supco manufactures test instruments and\r\nreplacement parts for heating, ventilation, air conditioning, and\r\nrefrigeration systems.
