    Abstract: A modular crossbar arrangement for molded case circuit breakers allows a plurality of contact arm assemblies to be interconnected from a single modular unit. To provide increased acceleration to the movable contact arms a contact arm accelerator lever interfaces with the contact arm and crossbar assembly. To promote further acceleration of the movable contact arms to their closed positions, the movable contact arms in a multi-pole circuit breaker are staggered with respect to their rotational alignment within each pole on the crossbar assembly.

    Abstract: A low-voltage circuit breaker of compact design has a housing of insulating material with several parallel disposed chambers. A switching mechanism designed as a structural unit is provided in one of the chambers. The other chambers comprise compartments for switching path contacts. The switching mechanism comprises a U-shaped carrier for all moving parts. In particular, a drive shaft with a coupling part, such as a key, as well as a tripping shaft, likewise having a coupling part such as a slot, are provided. A pole control shaft is provided for actuating the switch contacts and is provided at its end with a coupling part such as a slot which comes into engagement with the coupling part of the drive shaft of the switching mechanism if the latter is built into the switch gear.

    Abstract: A circuit breaker including first and second spaced-apart stationary contacts and a movable contact operable between open and closed positions with respect to the stationary contact wherein the movable contact, when in the closed position, conducts electricity between the stationary contacts and wherein the movable contact, when in the open position, is spaced apart from one of the stationary contacts. The movable contact has a longitudinal slot extending from one end thereof, and the movable contact is pivotally engaged to one of the stationary contacts at the movable contact end wherein the slot is located. The first stationary contact has an end portion thereof which is disposed within the movable contact slot. Also included are means for effecting movement of the movable contact between the open and closed positions.

    Abstract: A circuit breaker having stationary and movable contacts operable between open and closed positions with the movable contact being biased in an open position. The movable contact is mounted to a contact and spring holder which engages one link in a toggle means. The first link is connected to a second link which has a drive pin secured thereto, and the second link is pivotally connected to a toggle lever. A cam is secured to a rotatable drive shaft, and the cam engages a cam roller which is secured to a follower plate. The follower plate, which rotates about an axis different from the drive shaft axis, has a drive pawl attached thereto, with the drive pawl being disposed adjacent the drive pin. Spring means are pivotally connected to the follower plate and are capable of being in spring charged and discharged positions. The spring is charged by rotation of the drive shaft and cam causing the cam roller to move outwardly. The outward movement of the cam roller causes rotation of the follower plate, resulting in charging of the spring means. The degree of rotation of the cam during the charging rotation is more than twice the degree of rotation of the follower plate, thereby gaining a mechanical advantage. When the spring means discharges, it causes rotation of the follower plate such that the drive pawl is capable of engaging the drive pin to move the toggle means into toggle position. Upon moving into toggle position, the toggle means moves the contact holder and movable contact into closed position. Also included are releasable toggle and drive latch means for holding the toggle means in toggle position and the follower plate in the spring charged position, respectively.
