product description

NMGL series load disconnecting switch (hereinafter referred to as switch) is developed by our company with the introduction of advanced European technology. This product has an international level in the late 1990s. It is an ideal replacement product of similar products in China.

Switches are widely used in power distribution systems and automation systems in the construction, power, petrochemical and other industries.

Modular design structure, flexible and diverse combination, glass fiber reinforced unsaturated polyester resin for the outer shell, high dielectric properties, protection and reliable operational safety.

The operating mechanism is a spring energy storage, instantaneous release acceleration mechanism that instantaneously turns on and off the double break point contact structure. Independent of the speed of the operating handle, it greatly improves the electrical and mechanical properties.

A variety of structures and modes of operation, there is a window to directly observe the on/off state of the contacts, and there are cabinets and cabinets outside, with front and side operations, and rear panel wiring.

The switch is beautiful in appearance, novel, simple, and small in size. It is an ideal choice for similar products.

NMGL series products have obtained 3C certification.

Model meaning

Selection example

NMGLZ2-160A/4JF Il-380V In 125A conversion load disconnecting switch, left and right arrangement, AC rated voltage 380V, agreed heating current 160A, rated current 125A, 4 pole, outside the cabinet operation, auxiliary contact 1 normally open +1 often close.

Features

1. The acceleration mechanism of the spring energy storage instantaneous release realizes fast switching or breaking (13.8 m second), which has nothing to do with the speed of the operating handle, and greatly improves the arc extinguishing capability.

2. The outer shell made of glass fiber reinforced unsaturated tight resin has good flame retardancy, dielectric properties, carbonation resistance and impact resistance.

3. parallel double break point contacts have a white cleaning effect.

4. All contact materials are copper-plated silver alloys with two separate contact faces.

5. isolation distance is large.

6. In the “O” position, the handle can be locked with three locks at the same time to avoid misoperation.

Product Usage

NMGL series load isolating switch is mainly used for AC 50Hz, rated voltage 660v, DC rated voltage 440v, rated current to 3150A. Used for infrequently connecting and disconnecting circuits and circuits.
