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;

• Could be replaced for the module not need power off
Maximum current of endure the lightning stroke 40KA (8/20 us)
Time of response <25ns
The color of visible window shows operating status, green means normal,
red means abnormal
