摘要： The disclosed concept provides for an operating mechanism in a overload relay assembly having a solenoid with a permanent magnet. The solenoid includes a ferrous output member. The solenoid moves the output member between a first retracted position and a second extended position. When the output member is in the first retracted position, the permanent magnet maintains the output member in the first retracted position. Thus, in a system wherein the overload relay assembly interrupts power to its own operating mechanism solenoid, the permanent magnet maintains the output member in the first retracted position even when the solenoid is de-energized.

摘要： The disclosed concept relates to an overload relay and, more specifically, to an overload relay switch having a reduced number of components and less complex components. The reduced number of components includes the lack of a return spring on the manual actuators. Further, the relay switch member, which was typically a snap switch conducting member structured to change its configuration, is a substantially flat blade. Further, a circuit is used to detect an over-current condition and a solenoid actuates the relay switch assembly, thereby eliminating the need for a mechanical over-current detection and switch actuation device.
