SCB MCB

The backup protector plays a very important role, but it depends on whether your products are of good quality. Good quality will play a great role. You should use the backup protector for lightning protection. The direct effect of the backup protector produced by Zhejiang Leihao Electric Co., Ltd Lightning Protection Company and SPD is that the SPD backup protector will not be broken under heavy lightning impact; After SPD breaks down, the small power frequency current flow is cut off quickly to ensure the safety of power grid and power consumption.
When transient overvoltage occurs in the power supply line, the SPD is turned on, which will lead to power trip and accidents. After installing SCB backup protector, the circuit can be quickly disconnected when SPD is short-circuited by transient overvoltage, thus avoiding accidents caused by SPD breakdown. When lightning passes through, the SCB backup protector can effectively avoid false tripping, so that the surge protector is always in an effective state, ensuring the safety of power consumption.
