An electrically insulative case includes a door arranged to move between an opened position and a closed position and a rack mechanism arranged to move between an ON position and an OFF position. The electrically insulative case further includes an interlock including a plunger arranged to move between a locked position and an unlocked position. The interlock also includes an engagement mechanism that is coupled to the plunger. The engagement mechanism is arranged to move between a first position in which the engagement mechanism is spaced from the rack mechanism and a second position in which the engagement mechanism is engaged with the rack mechanism. The door is inhibited from moving to the opened position when the plunger is in the locked position. The plunger is arranged to move to the locked position when the engagement mechanism is in the second position and the rack mechanism is in the ON position.

A hand-held power tool, in particular an angle grinder, includes a gearing housing part and an accessory equipment. The gearing housing part includes at least one machine-side contact element. The accessory equipment includes at least one accessory equipment-side contact element. In the mounted state of the accessory on the hand-held power tool, the at least one machine-side contact element comes into contact with the at least one accessory-side contact element.

A trippable control system for one or more electrical breaker poles includes a first link pivotable about a first pivot point between first and second positions; a second link pivotable about a pivot axis for connecting to one or more breaker poles, whereby movement of the first link causes the second link to pivot about the pivot axis between a position for opening and a position for closing the breaker pole(s); and a trip mechanism suitable for releasing the first pivot point and for exerting a movement force on the first link to move the first link between the second and third positions when the first link pivots about a second pivot point. Movement of the first link between the second and third positions causes the second link to pivot about the pivot axis between the position for closing the breaker pole(s) and the position for opening the breaker gear.

An accumulator control system for one or more electrical breaker poles includes an accumulator mechanism presenting a control handle movable at least between breaking and closing positions; a first link connected to the outer carriage and pivoting about a first pivot point between first and second positions, by actuating the control handle of the accumulator mechanism between the breaking and closing positions; a second link pivotable about a pivot axis and connected to the first link by a sliding connection so that the movement of the first link, between the second and first positions, causes the second link to pivot about the pivot axis between a position for closing one or more breaker poles, and a position for opening one or more breaker poles. The control system is further configured to exert an additional pivoting force on the second link when the control handle is actuated beyond the breaking position.

An accumulator control system for one or more electrical breaker poles comprises: an accumulator mechanism presenting a control handle movable at least between breaking and closing positions; a first link connected to the outer carriage and pivoting about a first pivot point between first and second positions, by actuating the control handle of the accumulator mechanism between the breaking and closing positions; a second link pivotable about a pivot axis and connected to the first link by a sliding connection so that the movement of the first link, between the second and first positions, causes the second link to pivot about the pivot axis between a position for closing one or more breaker poles, and a position for opening one or more breaker poles. The control system further comprises means for exerting additional pivoting force on the second link when the control handle is actuated beyond the breaking position.

A stored energy assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing and a mount coupled to the housing. The stored energy assembly includes: a ratchet assembly having: a first ratchet member, a second ratchet member, and a shaft extending through the first ratchet member and the second ratchet member, the shaft being structured to extend through the mount; a stored energy mechanism coupled to the shaft; at least one charging mechanism structured to charge the stored energy mechanism in order to store energy; and a clutch assembly including a link assembly cooperating with the first ratchet member and the second ratchet member in order to transmit energy from the charging mechanism to the stored energy mechanism.

The present invention relates to a draw out apparatus for an air circuit breaker, and more particularly, to a draw out apparatus for an air circuit breaker capable of allowing a circuit breaker body to be stopped at a preset position, by executing idling when an abnormal operation such as an over-draw in operation and an over-draw out operation occurs at the preset position such as a disconnect position, a test position or a connect position, and capable of preventing damage of a circuit breaker and a cradle.
