Zener Safety Barrier is a very important device in intrinsically safety explosion-proof system. Usually speaking, when the system failure, internal fuse of general zener safety barrier is broken, you need to change the whole zener safety barrier. But if it is KAZ-37□□ series products, you just need to change the fuse but not the whole zener safety barrier.

KAZ-37□□ has five kinds of models which can compose intrinsically safe explosion-proof system with intrinsically safe instruments. It is an important device in intrinsically safe explosion-proof system and widely used in petroleum, chemical, pharmaceutical, shipbuilding and other areas
