How to reduce DC Isolating Switch failure frequency?
To fundamentally reduce the failure rate of DC isolating switch, you need a three-pronged strategy: selecting arc-resistant, certified components, such as Suntree's specialized models;
• Dual Voltage Rating: Suitable for both 1000V and 1500VDC systems.
• High-Current Protection: 315A-630A rated current with30kA/50kA breaking capacity.
• Ultra-Fast Operation: 1-3ms time constant for superior equipment protection.
• International Compliance: Meets IEC 60269-6 and GB/T13539.6 standards.
• Premium Materials: Pure silver melt and silver-plated cover for low resistance.
• High Efficiency: Low temperature rise and reduced power loss.
• Compact Design: Standardized dimensions for easy integration and space saving.
| MODEL | RATED CURRENT | POWER LOSS 1.0IN (W) | BREAKING CAPACITY | NET WEIGHT |
| SNHPV | 315A | 44.4 | 1000VDC/1500VDC: 20kA | 1.35kg |
| 350A | 52.3 | |||
| 400A | 58.2 | |||
| 500A | 52.5 | |||
| 630A | 91.9 |
