What is a Surge Protective Device (SPD)?
A Surge Protective Device (SPD) is an essential electrical component designed to protect electrical equipment from damage caused by sudden voltage spikes, known as surges. These surges can result from
• 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.
