High frame level 1P+N double breaking point(18mm width,module up top 4A), high breaking capacity(up to 6kA). Terminal with error protected teminal blocks, and higher safety with contact position indicating window. Current limited contact system, magnetic blow-out type arc exitinguishing device, can avoid products and equipment from large short circuit current, and improve the arc extingushing ability of products, then make sure the enhancement of breaking capacity. The shell and function keys are all made by PA66 nylon which with high flame retardant, high temperature resistance, impact resisitant plastics. Innovative appearance,reasonable structure and with multiple patent protection. The products with overload, short circuit, leakage protection functions.

A miniature circuit breaker (MCB) automatically switches off electrical circuit during an abnormal condition of the network means in overload condition as well as faulty condition. 

UNION provides reliable and tested miniature circuit breaker built with the first quality material. Union MCB design brings innovative approach to protection of arc chamber by leading the heat flow internally.

PA66 Nonflammable shell, trip units and handle, Q195 steel coated with Zn for the arc chamber and terminal PH joinery form with 24 HRC hardness, 6 aluminum rivet for stronger joints, 2 times ticker shell and heavier material for overcurrent faults and fire prevention.
