NLGLR series isolating switch fuse group (hereinafter to be referred as switch), adopts its case material by bulk molding compounds unsaturated polyester resin glass fiber reinforced plastic (DMC UPR). It  has high dielectric properties, protection capacity and reliable safety operation performance.
The operating mechanism adopts accelerating mechanism of spring storage and instantaneous release, double break contact mechanism of instantaneous making and breaking. The switch operating capacity has nothing on handle operating speed, which greatly improves electrical and mechanical performance. The isolating switch fuse group can ensure on-load making and breaking circuit and has reliable over current or short-circuit safe breaking protection. It also has good properties of resistance to heat and humidity.
The appearance of switch is attractive, novels and compact and overall functions, which is the best choice among similar products.
