Switch-disconnector-fuse

SIWOH1(GLR) series switch-disconnector-fuse 

Product General

SIWOH1(GLR) series switch-disconnector-fuse (hereinafter called as switch for short) is a kind of multipole manual operation switch. It adopts DMC enclosure which has high dielectric property，protective capability and operating safety.

The operating mechanism is an accelerating mechanism of spring stored energy and instantaneous release which instantaneously make and break multi-breakpoint contact structure. It has no relationship with the speed for operating the handle. Thus，greatly increase all electrical and mechanical properties.

The switch can ensure make and break circuit under load，the switch equipped with fuse which give reliable making and breaking protection to against over-current or short-circuit.

High resistance to wet heat.

The switch is beautiful，novel，simple，small size and has complete functions. It's the best choice among the similar products.

SIWOH1(GLR) series product has acquired China Compulsory Certificate.

Product Features

1. Accelerating mechanism of spring stored energy and instantaneous release realizes quick making and breaking (13.8m/s). It has no relationship with the speed for operating the handle. Thus ，greatly increase the capability of extinguishing electric arc.

2. The DMC enclosure has excellent flame retardant property，dielectric property，operating safely.

3. The parallel multi-breakpoint contact has self-cleaning function.

4. It can ensure make and break circuit under load，and has the function of reliable protection to against over-current or short-circuit.

5. It's safer，quicker and more convenient to change fuse.
