3.Key Features & Advantages
1. Engineered for Durability
Crafted from corrosion-resistant alloys and high-strength insulators, the GN19 withstands UV exposure, moisture, and chemical contaminants. Its triple-seal design ensures IP67 protection in outdoor installations.
2. Enhanced Safety
- Visible isolation gap for zero-voltage confirmation.
- Interlocking mechanisms prevent accidental operation during maintenance.
3. Grid Efficiency
Precision-engineered contacts reduce arc generation, lowering energy loss by up to 15% compared to conventional switches.
4. Customizable Configurations
Tailor the product for solar farms, railway substations, or mining sites with optional seismic bracing, extended busbars, or smart sensors.
4.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 GN19 uses a rotating blade mechanism to physically disconnect circuits. When the lever is engaged:
1. The blade pivots away from the contact point.
2. A 15mm isolation gap is created, visible through the inspection window.
3. Spring-loaded latches lock the switch in the "OFF" position.
