Each contact arm defines an opening, One movable contact is disposed on each contact arm. Each contact arm is rotatably coupled to the axle with the axle extending through the contact arm opening. Each isolation member is disposed adjacent at least one contact arm. Each isolation member is coupled to, and in electrical communication with the adjacent contact arm. The shunts are coupled to, and in electrical communication with, the isolation members. In this configuration, no shunt operatively engages a contact arm.

Modular switchgear and methods for manufacturing the same. The modular switchgear includes a vacuum interrupter assembly, a source conductor assembly, and a housing assembly. The vacuum interrupter assembly includes a bushing, a fitting, and a vacuum interrupter at least partially molded within the bushing and including a movable contact and a stationary contact. The source conductor assembly includes a bushing, a fitting, and a source conductor molded within the bushing. The housing assembly includes a housing defining a chamber and a drive shaft and conductor positioned within the chamber. The housing assembly also includes a first receptacle for receiving the fitting of the vacuum interrupter assembly and a second receptacle for receiving the fitting of the source conductor assembly. The vacuum interrupter assembly, the source conductor assembly, and the housing assembly are coupled without molding the assemblies within a common housing.

The disclosure relates to a pole part of a circuit-breaker arrangement having an insulation housing for accommodating a vacuum interrupter containing a pair of corresponding electrical switching contacts, wherein a fixed upper electrical contact is connected to an upper electrical terminal molded or assembled in the insulation housing and a movable lower electrical contact is connected to the insulating housing by a support plate of the insulation housing via a flexible conductor that includes a first end for attaching the flexible conductor to the lower electrical terminal and a second end for attaching the flexible conductor to the movable lower electrical contact. The second end of the flexible conductor is provided with an inside thread which is screwed to an outside thread arranged on the distal end of the movable lower electrical contact.

A conductor guide member for a circuit breaker terminal assembly includes a body having at least one conductor guide surface configured and disposed to facilitate alignment between at least one terminal connection member of the terminal assembly and at least one conductor. The at least one conductor guide surface gradually slopes from a first end to a second end. The second end defines a recess.

An improved connection apparatus that meets these and other needs includes, in one embodiment, an approximately J-shaped flexible conductor having at its end an opening that receives therethrough a portion of the shank for mechanical and electrical connection therebetween. The conductor further includes a hole formed therein at approximately its midpoint that receives therein, in a movable and non-contacting fashion, another portion of the elongated shank. In another pair of embodiments, another connection apparatus includes a flexible conductor that is co-formed with a rigid conductor to form a single piece unitary element. The free end of the flexible conductor is connected with the movable shank, and the rigid conductor is connectable with the primary conductor of the circuit. By providing the flexible conductor and the rigid conductor as a co-formed unit, a detachable fastener need not be employed to provide a connection therebetween, which reduces heat generation.
