Overview
The HGL series isolating switch is divided into 18 specifications from 125-3150A and is a modular design basic type. It has three poles and four poles (three poles+switchable neutral pole), suitable for circuit and connection and disconnection or electrical isolation. It is only used for electrical isolation above 1000A
There is a marking window on the front to indicate the on/off status of the contacts
◇ As needed, a rear observation window can be provided to directly observe the on/off status of the contacts. The window style can be seen in HGL-125~1600A/H cabinet for operating the load isolation switch
Operation method
◇ Direct operation: The handle is directly installed in the middle of the switch
◇ Out of cabinet operation: The handle is installed outside the distribution cabinet door
◇ Can be equipped with two sets of auxiliary contacts
Scope of application
The HGL series load isolation switch is suitable for circuits with AC 50Hz, rated voltage up to 660V, DC rated voltage up to 440V, and rated current up to 1600A. Used for infrequent connection and disconnection of circuits
Normal working conditions and installation conditions
The HGL series isolating switch can reliably operate under the following conditions
Altitude not exceeding 2000 meters
The ambient temperature shall not exceed 40C and shall not be lower than -50c
Relative humidity not exceeding 95%
◇ Non explosive hazardous medium environment
◇ No rain or snow invasion environment
Note: If it is expected to be used under conditions where the ambient air temperature is above+40 ℃ or below -5 ℃~-45 ℃, the user should inform the manufacturer when placing an order
