Product Q&A

Q:What is the extinguishing medium used in the FN18-12 load break switch?

The FN18-12 uses clean air as its insulation and arc-extinguishing medium via a gas-puffer (air-blast) mechanism, eliminating the need for SF6 gas or oil.

Q:Can the FN18-12 be supplied with fuse holders and an earthing switch?

Yes, it can be configured as a standalone switch or integrated with a high-voltage fuse combination frame and bottom earthing switch for complete short-circuit and circuit protection.

Q:Can FN18-12 be used for functional replacement of similar European air LBS models (such as NALF/NAL)?

Yes, FN18-12 is designed as a mature air-insulated load switch suitable for replacing or retrofitting standard NAL/NALF type units in secondary distribution switchgear, though exact mounting dimensions should be cross-verified for custom cabinet designs.
