LRD07 - Overload Relay

A 3-pole thermal overload relay, designed to protect AC circuits and motors against overloads, phase failure, long starting times and prolonged stalling of the motor. Operation of the test button allows checking of control circuit wiring and simulation of relay tripping (actuates both the NO and NC contacts). Stop button actuates the NC contact, does not affect the NO contact. Trip indicator. Setting locked by sealing the cover. Selector for manual or automatic reset. Deliberate action is required to move it to the automatic position.
