Key features

Three-phase linkage tripping mechanism guarantees automatic full opening within 60ms once any single-phase fuse blow occurs.

SF6-free air-blast insulation system compresses ambient air via mechanical piston action to extinguish electrical arcs cleanly.

Integrated mechanical "five-proof" interlocking structure prevents hazardous grounding closure during active live line states.

Product Q&A

Q:How does the FKRN12-12D protect the distribution transformer from single-phase running?

The FKRN12-12D is equipped with a tri-phase linkage mechanism. When a short-circuit fault happens, the striker of the high-voltage current-limiting fuse (such as XRNT or SDLAJ-12) ejects immediately, triggering the master operating mechanism to open all three phases within 60ms.

Q:Does this indoor load break switch contain SF6 gas for arc extinguishing?

No, the FKRN12 utilizes a pure air-blast method. During the opening sequence, an internal piston compresses air inside the cylinder to generate high-velocity airflow, blowing out the arc directly without using SF6 gas.

Q:What options are available for the operating mechanism and mounting direction?

The unit supports both manual spring charging and motor-driven mechanisms (AC/DC). It can be customized with either left-side or right-side operation arrangements to fit specific switchgear compartment layouts.
