Product Description

FN12-12(R)D/125-31.5 indoor AC high voltage load switch-- -fuse combination (hereinafter called FN12-12(R)D combination) is an indoor high voltage switch device which combines FN12-12D load switch and SOLAJ-12(XRNTC J-10)high voltage current limiting fuse. It can break reliably under any current except it is up to short-circuit current. The load switch breaks the working current and the fuse breaks the short circuit current.
