_REN6825 LH-SCB-40 SCB series backup protector for SPD_REN6823 LH-SCB-40 SCB series backup protector for SPD

This time we introduce the product we produce is the backup protector.

According to the relevant regulations of relevant standards (GB188021 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.

Features
