DESC:TECHNICAL FIELD OF THE INVENTION
The present invention generally relates to low voltage switching device(s) with the rear termination or with the plug-in module. More particularly, the present invention provides a module for providing ingress protection to prevent the circuit breaker from danger of hazards.

BACKGROUND AND THE PRIOR ART
A typical circuit breaker can be connected to the electrical circuit by various means. The way in which the conductors are connected is called as termination type. Termination of switching devices is made as per the requirement for it, i.e. standard type, box type or plug-in type, rear stud type. Plug-in module with the breaker is generally used where the ease of changing circuit breaker accessibility is needed like in frequent fault occurrence area. Rear studs are used where space optimization is required as well neat termination of circuit breaker on a panel, where the termination and other electric connections happen at the back side of the panel.
In the case of circuit breaker with the plug-in module/ rear stud, breaker termination is not visible from front unlike the spreader termination, link termination or cable termination, so the chances of the accidental access by unknown at breaker terminal is high(if proper indications are not provided), which is hazardous to human life if terminals are live. In above mounting conditions when phase barriers are placed for insulating adjacent poles during short circuit (ionized gases can create flash-over if not insulated properly), it requires more space on the panel and so on the cost of panel. Even with the proper indication of the breaker in on and off condition, it is dangerous to the person accessing the removing/mounting of the breaker, because one side will be always live (in case of plug in module) until upstream breaker is off (generally never happens).
In general practices, panel builders don’t use the phase barriers in the case of plug-in module/rear studs, because as mentioned above it requires more space and so the cost of the panel. In this case, the clearance and creepage between adjacent poles becomes very less, so the chances of shorting at breaker terminal is high by things like some insects, contamination on the breaker surface, spread of foreign particles of terminal surfaces etc.
US5894405 disclosed an assembly and method for mounting a plurality of circuit breakers for electrical and mechanical connection to a bus bar in a module of a distribution board. The mounting assembly includes each circuit breaker having a housing which is defined by a contact end for connecting to the bus bar, a mounting end for securing to the cell of the distribution board, and side panels extending there between. Each housing has a top surface and a bottom surface. The connect end of each housing has a bus bar terminal for connecting to the bus bar. At least one spacer is located between at least two of the circuit breakers. The spacer has a predetermined width between the side panels of adjacent circuit breakers. The spacer width is sufficient to spread the circuit breakers apart from each other and align the bus bar terminal of each housing with the busbar. A bracket is also provided with spacing flanges having a predetermined width to extend between the side panels of the circuit breakers sufficient to spread the circuit breakers apart from each other and align the connect ends of the circuit breakers with the busbar. Preferably, the mounting assembly pivotally mounts a line terminal within the housing of the circuit breaker permitting the slot of a contact jaw to move freely in a direction perpendicular to the busbar.
The above cited prior art doesn’t provide access of circuit breaker lifting and occupies the more space on the panel, less clearance between pole and ground in case of rear termination.
US7227740 disclosed a non-conductive bus shroud for a dual circuit breaker system that has a plurality of vertical walls extending generally perpendicular from the top side and including at least one bus member support vertical wall. The dual circuit breaker system includes a housing assembly having a back wall, a first circuit breaker having at least one protruding line terminal, a second circuit breaker having at least one protruding line terminal and at least one bus member extending between the at least one first circuit breaker line terminal and the at least one second circuit breaker line terminal. The bus shroud has a planar member with a top side, a bottom side, a front edge, a back edge, at least one first circuit breaker terminal opening, and a second circuit breaker terminal opening. When the shroud is installed over the circuit breakers, the vertical walls protect and support the bus member.
The above mentioned document doesn’t provide the lifting access of the circuit breaker in case of rear termination and with plug-in module and occupies more space on panel too.
In the current practices, circuit breaker with the plug-in module/ rear stud, breaker termination is not visible unlike the spreader termination, link termination or cable termination, so the chances of the accidental access by unknown at breaker terminal is high(if proper indications are not provided), which is hazardous to human life if terminals are live.
In above mounting conditions when phase barriers are placed for insulating adjacent poles during short circuit (ionized gases can create flash over if not insulated properly), it requires more space on the panel and so on the cost of panel. So generally panel builders don’t use the phase barriers with rear studs/plug-in module.
Even with the proper indication of the breaker in on and off condition, it is dangerous to the person accessing the removing/mounting of the breaker, because one side will be always live (in case of plug in module) until upstream breaker is off (generally never happens). So it is hazardous if proper lifting access is not provided. Generally panel builders don’t use the phase barriers in the case of plug-in module/rear studs, because as mentioned above it requires more space and so the cost of the panel. In this case, the clearance and creepage between adjacent poles becomes very less, so the chances of shorting at breaker terminal is high by things like some insects, contamination on the breaker surface, spread of foreign particles of terminal surfaces etc.
The present invention counters the all drawbacks mentioned above in existing /conventional practices and prior arts for providing protecting the circuit breaker with the rear studs/plug-in module.
