Key features

Three-Position Switch Integration: Combines Closed (ON), Open (OFF), and Earthed (EARTH) states in one SF6 gas chamber, eliminating mis-operation and ensuring earthing safety.

Leak-Free Epoxy Resin Housing: Sealed inside a high-strength epoxy resin cast shell with IP67 enclosure rating, preventing gas leakage and insulation breakdown in high-humidity areas.

12kV 630A Rated Performance: Delivers 630A rated current and 20kA/3s short-time withstand current, fully compliant with IEC 62271-103 and GB/T 3804 standards.

210mm Phase Distance Adaptation: Standard 210mm phase-to-phase distance design allows direct mounting inside XGN15-12 RMU cabinets and compact substations.

Dual Spring Mechanism Options: Supports K-type single spring for line control and A-type double spring (with fuse striker trip system) for transformer overload protection.

Product Q&A

Q:What is the standard phase distance for this FLN36-12 model?

The standard phase-to-phase distance for FLN36-12 is 210mm, matching standard XGN15-12 switchgear cabinet structures. Customized phase spacing can also be evaluated per design specifications.

Q:What is the difference between FLN36-12 and FLN36-24 models?

FLN36-12 is rated for 12kV systems with a standard 210mm phase distance, whereas FLN36-24 is designed for 24kV systems with a standard 230mm phase distance and higher insulation withstand voltage levels.

Q:Can this SF6 load break switch be motorized for remote automation?

Yes. Both K-type single spring and A-type double spring mechanisms support installation of AC/DC 110V/220V or DC 24V electric operating motors for SCADA integration.

Q:How does the A-type mechanism trip when a fuse blows?

When a current-limiting MV fuse blows, its integrated pin striker activates the mechanical linkage of the A-type double-spring mechanism, instantly opening all three phases of the LBS to protect the transformer.

Q:What parameters should be submitted to confirm a custom quotation?

Please confirm: Rated voltage (12kV), rated current (630A), mechanism type (K-type single spring or A-type double spring), control voltage (if motorized), phase distance, and auxiliary switch requirement.
