| The status monitoring system for a circuit breaker (100) includes a movable handle (110) with a magnet (112), a magnetic sensor (140) and a processor (150). The magnet is movable with the handle. The magnetic sensor is arranged in proximity to the handle, and is used to sense a magnetic field produced from the magnet of the handle. The processor receives information of the sensed magnetic field from the magnetic sensor and determines a status of the circuit breaker based on the sensed magnetic field which relates to a position of the handle. The status of the circuit breaker may include a handle position (e.g., ON, OFF or TRIPPED position), a handle velocity or a handle acceleration. A diagnosis of breaker functionality may then be reported. | ||||||
