General
Series Transfer Load-isolation Switch
YGLZ1-125~4000A
YGLZ1 -125~4000A. The load isolation switch is suitable for the
changeover of two sets of low voltage
electric circuit or the changeover of 2 sets of on-load devices
or safety insulation.
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 observe directly the on
and off state of contact.
The products have three poles, four poles, and (three poles+on
and off neural pole).
Extended shaft is used for the operation outside the board.
Two sets of auxiliary contacts can be assembled according to the
demand.
Mechanical property and electric property correspond to the
mechanical property and electric property
of YGL-125~4000A.
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 the inlet or outlet is conn-
ected with it.
