Test assembly for a circuit breaker

摘要

A test assembly (112) for a circuit breaker (100) with a single pole module (110) having first and second conduction paths electrically isolated from each other via an interior wall (111) of the module (110) and a circuit board (201). The test assembly (112) includes an axle (116) at an upper portion of the interior wall (111) and having a first end (116a) and a second end (116b) extending along opposite sides of the interior wall (111), a test actuation member (114) configured to be actuated, and a spring (115) in operable communication with the test actuation member (114) and in signal communication with the circuit board (201). The spring (115) contacts the test actuation member (114) and the first end (116a) of the axle (116) when the test actuation member (114) is actuated, the axle (116) conducts an electrical signal to the spring (115), and the spring (115) provides a test signal to the circuit board (201) initiating a test operation of the circuit breaker (100).
