Top Switch Disconnectors: Safety, Features, and Buying Guide

The HGL series isolation switch is divided into 7 specifications from 63A to 3150A and is a modular design foundation type, It has three or four levels (three levels+switchable neutral level), mainly used for circuit connection and disconnection.

Cut off or electrical isolation, rated current 1000A and above is only applicable for electrical isolation.

There is a marking window on the front to indicate the on/off status of the contacts.

A rear observation window can be provided as needed to directly observe the on/off status of the contacts, with a window style, Operate the isolation switch behind the HGL 160A~1600A/KH cabinet.

Can be equipped with two sets of auxiliary contacts

The acceleration mechanism with instantaneous release of spring energy storage achieves fast connection or disconnection (13.8 meters per second), independent of the speed of the operating handle, greatly improving the ability to extinguish the arc. The shell made of glass fiber reinforced unsaturated polyester resin has good flame retardancy, dielectric properties, carbonization resistance, and impact resistance. The parallel double break point contacts have self-cleaning function, and all contacts have two separate contact surfaces. The isolation distance is large, and when in the "0" position, the handle can be locked with three locks at the same time to reliably avoid accidental operation.
