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.
