Product Description

Timetric AC Load Breaker Switch Introduction

The AC Load Breaker Switch with fuse is a three phase switch equipment designed for breaking or closing load current, loop closed current, no-load transformer and cable charging electric current, and close short circuit current in 12kv, 50hz electric systems. The equipment is equipped with an earthing switch to withstand short-circuit current. The FKN12-12RD/125-31.5 air high voltage load break switch-fuse combination unit is composed of the FKN2-12D load switch and SLAJ-12(XRNT-12) H.V current-limiting fuse box, and it can reliably break short-circuit currents up to any current, including breaking work load switch current, fuse short-circult breaking current, and breaking joint working between the current and the full shor-circuit current in any over-current, while the fuse allows, through its impact load switch sub-gate.
