Description
BU1 Series Surge Protective Device (hereinafter referred to as SPD) is suitable for surge protection in low-voltage power distribution systems. It provides multi-level protection of Class A, B, C and D to ensure equipment safety. Its maximum continuous operating voltage ranges from 275 V to 460 V, meeting the requirements of different applications and grid configurations.
It is applied for power supply protection in industrial, building, civil aviation, financial, telecommunication, port and other systems. It suppresses the amplitude of transient overvoltages caused by lightning and switching overvoltage, diverts surge energy, and protects the safety of system circuits and equipment.
