Function
The present Busbar changed the outdated connection ways of miniature circuit breaker (MCB) to a new connection way with the characteristics of wider contact area , low power consumption and low temperature-rise.
Our company produce almost all kinds of busbars for MCB, which have good versatility and practibility.It has advantages of security and convenience to install and widely used in construction electrical devices such as low-voltage power box, distribution box, illuminated box and so on.
