SGLZ-125A～1600A change over load isolation switch
SGLZ-125A～1600A.The load isolation switch is suitable for the change-over of two sets of low voltage electric circuit or the chang-over of 2 set of load devices or safety isolation.
Mode of operation:
Direct operation:handle is installed on the switch.
Operation outside the board:handle is installed outside the door of power distributing board.
Products with observation windows can be provided according to the demand to obsvrve directly the ON and OFF state of contact.
The products have three poles,four poles,and(three pole+ON and OFF neural pole).
Extended shate is used for ther operation outside the board.
Two sets of auxiliary contacts can be assembled according to the demand.
Mechanical performance and electric property correspond to the mechanical performance and elextric property of SGL-125A-1600A.
A bridge can provided to connect the inlet or outlet terminal of the switch.
Note:The bridge connection is chosen,an explanation is needed to indicate ther indicate the inlet or outlet connected with it.
