Abstract
Abstract A combination motor starter and protector module is described. The base member, in one embodiment, forms a motor protector compartment and a motor starter compartment. The motor protector, in one form, is a bimetallic switch configured to be coupled between a power source and the motor windings. The switch includes a stationary contact and a movable contact. A bimetal element, responsive to current flow through the protector, controls movement of the movable contact. The starter, in one form, is a positive temperature coefficient resistor (PTCR) disk configured to be connected in series circuit with the motor start winding. The cover of the combination housing includes, in one form, an integral capacitor support arm and terminal openings for receiving blade terminals of a run capacitor. The terminal openings in the cover align with blade receiving receptacles coupled to the PTCR start circuit. The blade terminals of a run capacitor are inserted into the receptacle openings and into electrical engagement with the blade receiving receptacles. The capacitor is supported by the module cover, including the capacitor support arm.
