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