Nlglr Series Load Isolating Switch Fuse Group

Model NO.: NLGLR Series
HS Code: 88
Scope of Application
 
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.
