An electronic circuit breaker comprises an electronic circuitry and a lockout mechanism configured to provide a safety feature. The lockout mechanism includes a trip rod placed along a longitudinal axis of the electronic circuit breaker. The trip rod has first and second ends. The lockout mechanism further includes a barrel mounted coaxially around the trip rod near the first end of the trip rod. The lockout mechanism further includes a moving arm mechanically coupled to the trip rod. The lockout mechanism further includes an electronic-powered magnet mounted coaxially on the trip rod near the second end being opposite of the first end of the trip rod. The lockout mechanism further includes an armature mechanically coupled to the trip rod. The barrel serves to block the moving arm and the trip rod is pushed by the electronic-powered magnet to interact with the barrel to remove a lockout such that the electronic-powered magnet is activated to push the trip rod to pull on the armature, causing the electronic circuit breaker to be tripped.

An electrical outlet receptacle including a circuit board defining a first plane and a solenoid having a central axis perpendicular to the first plane. The electrical outlet receptacle further including a reset plunger with a portion extending through the first end of the solenoid and axially movable therein, and an armature movable axially along the portion of the reset plunger extending through the solenoid. Wherein the armature includes a slanted projection configured to contact a cam surface of a slide mechanism and provide the downward force on the cam surface.

An arc quenching device creates a fault on a bus. A lockout mechanism of a circuit breaker feeding the bus is responsively actuated. Actuating the lockout mechanism may include releasing a spring-loaded mechanism mounted on a cassette that holds the circuit breaker to cause the mechanism to engage a lockout member of the circuit breaker.

A switchgear, in particular a circuit protection device, includes: a housing; a fixed contact that is fixed to the housing; a movable contact, the movable contact being arranged on a contact arm that is arranged in the switchgear so as to be movable; a latching device that is connected to the contact arm; a manual actuation device that has an actuation projection, which manual actuation device is connected to the latching device by a bar, the movable contact being brought into contact with the fixed contact when the actuation projection is moved from an off-position of the actuation projection to an on-position of the actuation projection. When the actuation projection is moved from the on-position towards the off-position as far as a specified trip position of the actuation projection, the bar remains still. When the projection is moved past the trip position, the bar is moved past a holding point.
