摘要： A supplemental magnetic trip unit is arranged on the load strap of an industrial-rated circuit breaker to interrupt circuit current upon occurrence of a short circuit fault. The trip unit employs a U-shaped magnet and a hinged armature that articulates the circuit breaker operating mechanism latch to allow the circuit breaker contacts to become separated upon the urgence of the powerful circuit breaker operating mechanism springs.

摘要： An operating mechanism controls and trips a separable contact structure arranged in a protected circuit. The mechanism includes a frame, a drive member pivotally coupled to the frame, a spring pivotally connecting the drive member to a drive connector, an upper link pivotally seated on the drive connector, a lower link member pivotally coupled to the drive connector, a crank member pivotally coupled to the lower link member for interfacing the separable contact structure, and a cradle member pivotally secured to the frame and pivotally securing the upper link. The cradle member is configured for being releasably engaged by a latch assembly, which is displaced upon occurrence of a predetermined condition in the circuit such as a trip condition. The mechanism is movable between a tripped position, a reset position, an off position, and an on position. Spacers are operatively positioned between movable members, and protrusions are operatively formed on the enclosure of the contact structure. The spacers and protrusions serve to widen the stances of the operating mechanism for force distribution purposes, and also to minimize friction between movable components.

摘要： A draw out interlock mechanism comprises a draw out trip arm pivotally attached in a draw out circuit breaker and an interlock activating assembly attached to a the draw out circuit breaker. The draw out trip arm comprises a first extension on a first end and a second extension on a second end. The first extension is positioned to interact with a trip latch of the operating mechanism. The interlock activating assembly comprises an extended arm and a camming arm, which are pivotally attached to a pin supported by a mounting bracket attached to the draw out circuit breaker. The extended arm extends through an aperture in the draw out circuit breaker with an end thereof proximate to the second extension of the draw out trip arm. The camming arm is adapted to interact with a camming surface attached to the draw out circuit breaker compartment such that when the draw out circuit breaker is inserted into the compartment, the camming arm and the extended arm rotate independently clockwise, the extended arm interacting with the draw out trip arm causing the draw out trip arm to rotate in counterclockwise, which in turn causes the first extension of the draw out trip arm to interact with the trip latch causing the draw out circuit breaker to trip, opening the contacts in the draw out circuit breaker.

摘要： A trip actuator (66) includes a trip spring (106) to bias the trip arm (104) in a clockwise direction about trip arm pivot (120). In the latched and ready to operate state, the clockwise moment about the axis of the latch pivot (132) created by force “F” opposes the counterclockwise moment created about the axis of the latch pivot (132) created by the horizontal component “fx” of force “f”, to hold the latch (110) in the upright position against the force of the trip arm (104). When a trip (triggering) signal is provided to the flux shifter (102), the flux shifter (102) releases the plunger (130). With the force “F” removed, the trip arm (104) will drive the latch pin (134), causing the latch (110) to rotate counterclockwise about the latch pivot (132). As the latch (110) and trip arm (104) rotate, the latch pin (134) slides off the latch surface (126), fully releasing the trip arm (104) and allowing the trip paddle (96) to move the secondary latch tab (50).

摘要： A circuit breaker having a crank for coupling a switching mechanism to the contact pole structure is presented. The crank has a pair of cam surfaces which cooperate with a blocking lever to restrict movement of the operating handle when the contacts of the circuit breaker are welded. The blocking lever is arranged such that it does not interfere with the handle under normal operating conditions.
