Abstract

A trip latch assembly (100) is provided for an electrical switching apparatus (2) such as a circuit breaker. The circuit breaker operating mechanism (8) includes a pole shaft (10). The trip latch assembly (100) includes a trip latch (102) pivotably coupled to the circuit breaker housing and being movable between a latched position and an unlatched position. A trip latch reset spring (104) is structured to bias the trip latch (102) toward the latched position. A spring housing (106) at least partially overlays the trip latch reset spring (104). A trip latch spring link (108) includes a first end (110) movably coupled to the pole shaft (10) and a second end (112) cooperating with the spring housing (106). When the circuit breaker needs to be reset the trip latch spring link (108) engages the spring housing (106) in order apply torque to the trip latch reset spring (104). When the circuit breaker (2) is closed the bias of the trip latch reset spring (104) on the trip latch (102) is removed.
