Abstract
A solid state relay structure for use with different alternating current motors having a range of full load current and service factor ratings. The relay includes a rectangular housing and bores extending through the housing through which conductors to the motor are passed. The rear end of the housing is spaced from the panel on which the relay is mounted so the conductors may be looped through the bores when portions of the looped conductors are passed in the space between the rear end of the relay and the panel. The solid state components of the relay are encapsulated in the interior of the housing and are connected to switches, terminals, and a light emitting diode located at the front of the housing so the relay may be easily programmed for use with motors having different ratings. The terminals and operating and test instructions, located at the front end of the relay, provide a convenient arrangement for wiring the relay in its control circuit and information to program the relay.
