Product Overview
The FZN Series Indoor Solid-Sealed Vacuum Load Break Switch and its combination units integrate vacuum interrupter solid-sealed poles with disconnectors, earthing switches, fuses, and spring operating mechanisms in a compact design. Engineered for 12kV, 3-phase, 50Hz AC power distribution networks, these units are ideal for both ring and radial power supply systems.
They are designed to:
- Make, carry, and break normal rated load currents
- Make load currents and withstand short-circuit currents for specified durations
- Provide overload and short-circuit protection for distribution transformers and other electrical equipment (in combination unit configurations)
With a rated current of up to 1250A, the VL1 series is a pioneering solution in the domestic market, delivering enhanced performance for modern power distribution requirements.
Core Features & Benefits
- Solid-Sealed Vacuum Interrupter Poles: Vacuum interrupters and conductive connections are encapsulated in epoxy resin via a special casting process, ensuring excellent insulation performance and adaptability to harsh, polluted environments. This design also enables the miniaturization of switchgear.
- High Rated Current: Industry-leading 1250A rated current, providing superior capacity for modern power distribution systems.
- Integrated Design: Combines load break switches with disconnectors, earthing switches, and fuses for comprehensive protection and switching functions.
- Flexible Operation: Equipped with manual or motorized spring operating mechanisms, with side-mounted installation for space efficiency.
- Compact & Lightweight: Optimized structure allows for easy integration into switchgear panels, reducing footprint and installation complexity.
- Interoperability: Compatible with the VS2 Series Indoor Solid-Sealed Vacuum Circuit Breakers, enabling seamless assembly in the same switchgear.
