Solid-state circuit breaker includes airgap operating mechanism configured to operate in limited space

A solid-state circuit breaker comprising:

• an airgap operating mechanism including components;
• and
• a housing that houses the components of the airgap operating mechanism such that each component in the operating mechanism is configured to achieve functions of ON, OFF, and TRIP,
• wherein the components of the operating mechanism include:
• a contact arm,
• a handle,
• an armature,
• an armature pivot feature and a stopper feature that work together to allow the armature to be able to have a stable pivot and a reset mechanism,
• a cradle, and
• a stopper pin configured to stop the cradle during a TRIP operation utilizes less space in comparison to a traditional method of using a thick plastic wall to surround the cradle at its stop.

• a housing that houses the components of the airgap operating mechanism such that each component in the operating mechanism is configured to achieve functions of ON, OFF, and TRIP,
• wherein the components of the operating mechanism include:
• a contact arm,
• a handle,
• a double pivot of the contact arm and a handle feature in that the contact arm has two-pivot legs to provide a double pivot of the contact arm and the handle such that the two-pivot legs reduce a pop-out force, which is a detrimental force from an operating spring pushing parts out of the solid-state circuit breaker during an assembly process,
• an armature,
• an armature pivot feature and a stopper feature that work together to allow the armature to be able to have a stable pivot and a reset mechanism,
• a cradle, and
• a stopper pin configured to stop the cradle during a TRIP operation utilizes less space in comparison to a traditional method of using a thick plastic wall to surround the cradle at its stop.
