◆DGLZ1-125~4000A. 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 DGL-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 connected with it. |
