The modular design of QGLR fuse combination switch,multi-polar may supply the choice, has the nimble diverse combination for

1.introduction

QGLR  fuse combination switches is a kind of multi-poles hand-operated switch, adopting the shell made of unsaturated polyester resin reinforced with glass-fibres, having very high dielectric performance, protective capability and safe operation.

The operating device is an elastic- accumulating and acceleating instant-release device, which makes instant making and breeking of the double gap contact,It has no relationship with the operating handle and thus greatly increase both the various electrcal and mechanical performance.

The fuse combination switches can assure the circuit to be turned making and breaking under load,having reliable breaking protection against over-current or short circuit apparent visible the off state.

Having strong humidiy and resistant properties.

The switch has an artistic, novel, succinct, small--sized outline, but has various function, being the best choice among the congeneric products.
