Example for lectotype: Rated current 630A, include neutral pole transferring loadisolation switch, DGL Z-630A/4J for operating outside of cabinet |
|
|
DGL Loadisolation switch can be divided into 18 specs from 125A to 4000A, it is the basic type of module 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. |
