Havells Busbar Chamber System
Havells busbar chamber system is designed for safe, reliable & economical distribution of power to various loads as per the requirements of the system. The modular construction of the bus bar chamber provides for compact & easy add-on modules on the basic unit for system expansion (if the need be). These can be wall mounted and can also be made suitable for floor mounting by using optional pedestal set.
the busbar chambers are available for 100a/200a, 250a/315a/400a & 630a/800a current ratings with short circuit withstand capacity of 25ka, 35ka & 50ka respectively.
these are offered in 4 way, 6way & 8 way in four pole configuration.
- fully application oriented as per
- is:8623/iec 60439 (panel sub assemblies)
- is: 2147/iec60529 (degree for protection)
the busbar chambers find wide application in power distribution in areas namely :
- construction site
- shop floor
- multistoreyed complexes
- building installation etc.
- readymade & customised solution for safe power distridution
- modular/compact design provides economy of space and cost
- simple and efficient system configuration
- easy, flexible and time saving installation
- shock proof design
- elegant & sleek in appearance
the busbar chamber is fabricated using sheet steel (crca) of 1. 6mm thickness and epoxy powder coated to give superior & lasting finish. The bus bar sections are made of etp grade copper & dull tin plated and the bus bar supports are made of dmc (dough moulding compound). The neutral bus bar is fully rated.
in bus bar chambers upto 200a, the bus bar layout is in a single layer (i. E. One by the side of the other & duly separated/supported on the bus bar support). Whereas in bus bar chambers of 250a / 315a / 400a / 630a / 800a, the busbar layout is in form of stack (i. E. One bus bar behind the other duly separated/supported by bus bar support). All have detachable end plates enabling them to be extended easily with the connection of another chamber. Full top and bottom end plates are detachable.
