Solid-state circuit breaker

A solid-state circuit breaker, comprising

• a housing;
• a contact assembly, configured to switch between an open state and a closed state, the contact assembly being off in the open state and conductive in the closed state;
• a semiconductor element, connected in series with the contact assembly;
• a handle, configured to move between an open position and a closed position, wherein the contact assembly is switched to an open state upon the handle moving to the open position, and the contact assembly is switched to the closed state upon the handle moving to the closed position;
• a first microswitch, fixed to the housing and capable of being triggered to generate a first signal;
• a second microswitch, fixed to the housing and capable of being triggered to generate a second signal;
• a first trigger part, coupled to the handle to move with a movement of the handle;
• and
• a second trigger part, coupled to the handle to move with the movement of the handle,
• wherein, during a movement of the handle from the closed position to the open position, before the contact assembly is switched to the open state, the first trigger part triggers the first microswitch to generate the first signal,
• during a movement of the handle from the open position to the closed position, before the contact assembly is switched to the closed state, the second trigger part triggers the second microswitch to generate the second signal.
