Applications

1.Breaking off through power frequency current and lighthing current, effectively protects SPD from fusing short-circuit due to abnormaltransient overvoltage, prevents from serious fire accidents.

2.Achieved selective breaking off for throughed frequency current and lightning current.effectively protects SPD from deteroration resuling in start voltage falling to less than the power supply voltage and increasing of

leakage current, prevents from serious fire accidents.

3.When SPD has a lightning current,the extermnal disconnector wil not be tripped by mistake, so that lighting protection of electrical equipment is always in valid state.

Scope of application

SCB-SPD specal backup protector provides professional backup protection forSPD(Surge Protection Device) which provides protection for the frst level, second level and third-level equipment it is suitable for places

where SPD lightning protection equipment has been

installed,such as power equipment in industial and residential buildings, electrical, communications, road and transportation, petrochemical and other industries.
