3 Phase Fused Disconnect Switch

The 3 phase fused disconnect switch produced by GRL Company usually refers to the non-outdoor fuse switch. The ac fuse switch is commonly used in the electric power field.

The ac power switch with fuse is collectively referred to as the 3 phase switch fuse unit, or it can be 3 single phase The fused disconnect switch is combined into a 3P nh fuse switch disconnector.

Common voltage 48v fused disconnect switch, 480v fused disconnect switch, 240v fused disconnect switch, 500v fused disconnect switch, 600v fused disconnect switch, 690v fused disconnect switch, 800v fused disconnect switch.

Product description:

This type of fused electrical switch is a 3 phase fused disconnect switch, model DNH1G. It is used together with NH series fuses, so it is commonly called nh fuse switch disconnector, and it can also be called blade fuse switch with an isolation knife.
This fuse switch produced by GRL has a unique appearance, different current specifications, and different materials. The main material of the shell is PA66 resistance V0, PC, DMC, composition. The copper parts are made of red copper.
