3.Key Features & Advantages
1. Built to Withstand Extreme Conditions
The product uses hot-dip galvanized steel and aluminum alloys to resist corrosion in coastal or high-humidity environments. Its IP65-rated sealing prevents dust and water ingress, ensuring reliable performance during storms, ice buildup, or temperatures up to 55°C.
2. Low Maintenance, High Endurance
With a mechanical lifespan exceeding 10,000 operations and self-lubricating bearings, this switch minimizes upkeep costs. Precision-aligned contacts reduce energy loss, while modular components enable swift replacements.
3. Safety First
An interlock system prevents accidental operation, and the earthing switch ensures zero residual current during maintenance. Arc-resistant materials and fail-safe mechanisms add layers of protection for personnel.
4. Smart Grid Ready
IoT-enabled variants (optional) integrate seamlessly with SCADA systems for real-time monitoring, helping utilities transition to automated, data-driven grids.
4.Real-World Applications
Be used in a wide range of industries.

Industrial Plants
Eliminate power factor penalties in CNC machines and assembly lines while handling surge currents up to 100x rated capacity.

Substation
Stabilizes substation voltage against harmonics and intermittent generation from renewable inverters.

Commercial Buildings
Retrofit aging systems in hospitals or malls with silent (<45dB), flame-retardant capacitors that meet NFPA 70 fire codes.
5.How It Works?
The product operates via a rotating insulator column, which physically separates contacts to break the circuit. The earthing switch provides a safe discharge path for trapped charges. Its through-wall mounting allows installation in tight spaces without compromising accessibility.
