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: 160A rated current with 20kA breaking capacity.
• Ultra-Fast Operation: 1-3ms time constant for superior equipment protection.
• International Compliance: Meets IEC 60269-6 and EN 60269-6 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.
