Table

One NO and one NC	11	NO+NC
Two NO and Two NC	22	2NO+2NC

Example for lectotype:Rated current 630A,include neutral pole transferring load isolation switch,DGLZ-630A/4J for operating outside of caninet.

DGL-125A~4000A LOAD ISOLATION SWITCH

DGL Load isolation switch can be divided into 15 specs from 125A to 4000A,it is the basic type of module design,it has three poles and four poles(three poles+swtich neutral pole),applied to make and break ciruit 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.
