When the transient overvoltage occurs in the power supply line, the SPD will be fused through, which will cause the power supply trip and accident. After installing SCB backup protector, when SPD transient overvoltage short circuit occurs, the circuit can be quickly disconnected to avoid accidents caused by SPD penetration. When the lightning current passes through, SCB backup protector can effectively avoid false tripping, make the surge protector always in an effective state, and ensure the safety of power consumption. 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 LEIHAO 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.

According to the relevant regulations of relevant standards (GB/T 1880211 and GB50057), the front end of the SPD circuit must be connected in series with overcurrent protection appliances. The existing general-pass current protection appliances on the market are mostly used to protect the fuses or circuit breakers of the back-end electrical equipment. They cannot effectively coordinate with the SPD, and it is difficult to realize the lightning protection function. In serious cases, it may even cause a fire.
Product structure and performance characteristics.
1. when transient overvoltage occurs in power line, SPD conduction will break through short circuit, which will cause power trip and accident. after SCB backup protector is installed, circuit can be quickly disconnected when transient overvoltage short circuit occurs in SPD, so as to avoid accidents caused by SPD breakdown.

2. When lightning passes through, SCB backup protector can effectively avoid false tripping, so that surge
protector is always in an effective state, ensuring the safety of electricity consumption.
