Detailed Product Description

Construction Features:

 CYD/C16 series miniature circuit breakers are composed case, operating mechanism,
contact system, arc-extinguishing system, tripping mechanism, etc. The caseis made of the soecial plastic high in fire-resistance and strength, so it is very capable of resisting impact and light in weight. The parts of the openratingmechanism employ high strength plastic products in order to assure the flexible,reliable operation and obtain the minimum moment of the tripping mechanism is very little. The tripping mechanism and short-circuit instantancous electromagneticmechanism. The contact arc-extinguishing system cmpoys the special arc conducting angle and gangway arc-extinguishing chamber so it has distinct current timiting characteristics.
