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;
• High-Performance Protection: 20kA breaking capacity with ultra-fast 1-3ms operation for superior safety.
• Dual Standard Compliance: Certified to both IEC 60269-6 and EN 60269-6 for global PV applications.
• Enhanced Durability: Withstands ≥24h salt spray test, ensuring reliability in corrosive and acidic environments.
• Optimized Terminals: Silver-plated copper terminals ensure low contact resistance, minimal temperature rise, and high conductivity.
• Robust Ratings: Designed for high-voltage systems with 1500VDC and 160A capacity.
| MODEL | RATED CURRENT | RATED VOLTAGE | FITTED WITH FUSE-LINK MODEL SIZE | NET WEIGHT |
| SRD-30 | 160A | 1000Vdc/1500Vdc | SNHPV | 0.322kg |
