The Present of copper busbar changed the outdated connection ways of Miniature circuit breaker(MCB) to a new connection way with the characteristics of wider contact area ,low power consumption and temperature-rise.

We produce almost all kinds of busbars for MCB,which have good versatility and practility.

It has advantages of security and convenience to install and widely used in construction electrical devices,such as low-voltage power box ,distribution box, lighting box and junction boxes, etc.

1.Increased contact area,reducing power consumption,reducing the temperature rise.

2.The busbar is in the insulation tank,so human does not touch the charged body. It is safe,reliable,time-saving,convenient.
 

3.Made of pure copper,Good conductivity,low contact resistance and complete specifications.
