,TagSPECI:TECHNICAL FIELD
The present subject matter described herein, in general relates to an electrical parts, and more particularly, to an improved design of bracket for support to circuit breakers pole shaft.

BACKGROUND
A multi-pole or multi phase circuit breaker assembly is used to indicate an electrical apparatus that carries out both function of breaking i.e., cut off and make of an electric circuit, in presence of normal operating current as well as in presence of short circuit current.

To operate multi phase circuit breaker, requires a mechanism (15) which will operate pole assemblies in all phases in synchronism. The mechanism (15) is connected to pole assemblies through a cross bar, it can be called as pole shaft (13).

A length of pole shaft (13) depends upon number of pole assemblies used in electrical device like circuit breaker (16). To operate all phase at same time, the mechanism linkages guide this pole shaft (13). For instance, when ON command is issued by mechanism (15), the pole shaft (13) gets rotated through desired angle and further drives all pole assemblies to close simultaneously.

In prior arts, due to inevitable play/gaps in mechanism linkages, the pole shaft (13) at different locations though get rotated completely, closing or opening of poles did not occur exactly at same time. This results in phase lag or inadequate contact pressure in poles. Further, the earlier arts used bearings to remove this inherent play and to improve pole closing. Also, the pole shaft (13) support had a complex design which required use of eccentric bearings inside it. On virtue of eccentricity, mechanism play was minimized. It was not easy to assemble on pole shaft (13).

Thus due to above mentioned drawbacks, there is need for a mechanism to overcome the drawbacks and propose new reliable design of brackets which the support pole shaft (13) efficiently.
