Product description 1-GLR series fuse combination switches (hereinafter called as switch for short) is a kind of multi-poles hand-operated switch, adopting the shell made of unsaturated polyester resin reinforced with glass-fibers, having very high dielectric performance, protective capability and safe operation. 2-The operating device is an elastic-accumulating and accelerating instant-release device, which makes instant making and breaking of the double gap contact. It has no relationship with the operation handle and thus greatly increase both the various electrical and mechanical performance. The fuse combination switches can assure the circuit to be termed making and breaking under load, having reliable breaking protection against over-current or short-circuit apparent visible the off state. 3-Having strong humidity and heat resistant properties. 4-The switch has an artistic, novel, succinct, small-sized outline, but has various functions, being the best choice among the congeneric products.
