General YGL series Load
isolation switch can be divided into 18 specs from 125A to 4000A, i t is the basic type of mod ule design, it has three poles and four poles ( three poles + switch neutral pole), applied to make and break circuit or electric isolate, over 1000A is only for electric isolation.
Symbol window on front face indicates the contact on-off state.
Operation mode Direct operation: The handle is installed in the middle of switch directly.
Operate outside of cabinet: The handle is installed outside of distribution cabinet.
It can be assembled two groups auxiliary contacts.
Application
AC 50Hz, rated voltage 660V, DC rated voltage 440V, rated current 1600A. It is used for making and breaking circuit infrequently.
