Surge Special Circuit Breaker (SCB) basic info:

Surge special back-up protection device, referred to as SCB or SSD, is a lightning protection device in recent years, more than 120 years later than the fuse. Its working principle is based on the lightning current and power frequency current transmission speed of different, through the internal circuit design, to achieve the transient current and power frequency current to distinguish, and through different paths to shunt it.


Surge Special Circuit Breaker (SCB) characteristics:

1.Lightning current shock continues to open, lightning protection continues to be effective, T1 level up to 25 Ka

2.Abnormal power network, power frequency current 3A speed off, SPD does not fire

3.Residual low pressure, equivalent fuse, more safe protection equipment


Deficiencies that SPD work togther wih fuses or circuit breakers:

Currently, fuses or circuit breakers used in a large number of SPD facilities are not compatible with each other in the following three aspects

1, lightning current impact, misbreaking, easy to damage -- SPD can not play the lightning protection function;

2, SPD short circuit, power frequency continuous current is not broken - SPD failure or short circuit line current is not large, difficult to meet the requirements of the fuse and circuit breaker breaking current, fuse and circuit breaker can not break the current, easy to cause SPD heat spontaneous combustion, cause fire accident;

3, lightning current impact, high residual pressure - equipment lightning protection reliability is reduced.


In view of the above products are not coordinated, our company has developed this series of SPD back-up protector products through long-term research and development and a large number of test verification, which can effectively coordinate with SPD, achieve lightning protection function, and solve the problem of safety hidden trouble when using fuses or circuit breakers as SPD back-up protectors.


The direct effect of using the surge backup protector with SPD is: under the big lightning shock, it is not divided to ensure the effective play of the lightning protection function; In case of SPD failure, the small power frequency current flow is rapidly broken off to ensure the safety of power grid and electricity use.
