High and low voltage switchgears are prone to generate arc light above 10000℃ in case of short-circuit faults, which can burn equipment and cause fires in only 0.1 seconds. Pufeike Electric's switchgear products are equipped with a standard "arc protection system", which links optical sensors (response time ≤1ms) with high-speed circuit breakers to realize the whole process of "fault detection - signal transmission - opening and power-off" in ≤5ms, which is 50 times faster than traditional overcurrent protection. This technology can effectively limit the release of arc energy, reduce equipment damage rate by 90%, and avoid the risk of electric shock for operation and maintenance personnel. It has passed the IEC 62271-200 standard certification and is widely used in key scenarios such as chemical industry and data centers.
