Abstract
An overload relay trip mechanism includes a housing, a reset button, a leaf spring, a test button, a coil spring, and an actuator. The reset button can be actuated from a normal position to a reset position to cause the leaf spring to transition from a first position to a second position, which causes a reset actuator-engaging element to move the actuator from a tripped position to a closed position. The test button can be actuated from a normal position to a test-stop position to cause a first test actuator-engaging element to move a moveable contact from an electrically connected position to an electrically disconnected position. The test button can further be moved from the test-stop position to the test-trip position to cause a second test actuator-engaging element to move the actuator from the closed position to the tripped position.
