What is a DC Surge Protective Device？
DC Surge Protective Devices (SPD) are essential for safeguarding electronic systems from voltage spikes, ensuring both reliability and efficiency. Their ability to absorb and redirect excess voltage helps ...
• Small volume and large current,saving installation space.The rated current 63A miniature circuit breaker isonly 18mm wide, saving 30% space.
• Strong environmental adaptability and reliableoperation in extreme environment.
5℃-40 ℃ ambient temperature application range,to meetthe application needs of various occasions.
• More reliable performance.Temperature rise ≤55K, breaking capacity up to 6ka electricallife ≥4000 times.
• Lighter operation.63A product has lighter operation force and is easy to operate.
• Contact indication window with clear position. The whole series of contact positions are visualized to avoidmisoperation and more reliable use.
