FN12-12D 12KV load break switch 630A 1000A

1. General

FN12-12D/630-50 indoor AC high voltage loadbreak switch, rated voltage is 12KV, rated frequency is 50Hz. It is a kind of threephases high voltage switch equipment. It can be used to breaking- closing loadcurrent, closed current, charge current for no-load transformer and cable,closing short-circuit current. The Load break switch which assembleds earthingswitch can sustain short-circuit current.

FN12-12DR/1000-31.5 indoor AC high voltageload break switch-fuse combination electrical appliance is a combinated indoorhigh voltage switch equipment which combinated by FKN12-12D load break switchand S□LAJ-12(XRNT□-12)high voltage limiting current fuse. Thisappliance can open any current up to short circuit current; Load break switchopen working current, Fuse open short circuit current, combination open anycurrent from working current to short circuit current, meantime Fuse makes theLoad break switch opening through striking
