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;
• SHXC-125PV/250PV
• Rated current :16, 20, 25, 32, 40, 50, 63, 80, 100, 125, 63, 80, 100, 125, 160, 200, 225, 250
• IP65 design, waterproof, anti dust and anti ultraviolet.
• The box body is made of PVC plastic material.
