UL 94-V0 Flame Retardant 400VAC 4P Surge Circuit Breaker

 
Surge Special Circuit Breaker (SCB) product feature:
40KA(8/20us) discharge current capability 
UL94-V0 flame retardant

The ability to withstand the impact of current is strong, no wrong action;
Power frequency current through more than 3±1A trip;
Running short circuit current breaking ability is strong;
Residual low pressure, protect equipment handy.effect is more better than fuse
High short-circuit current with maximum amplitude of 100kA can be cut off to protect SPD from TOV damage.
It can withstand the limp or lmax corresponding to SPD and keep on opening, and perfectly cooperate with SPD discharging current
 
Product Parameter

 
The fuse, circuit breaker work with SPD can not do:
1, SPD deterioration, distribution line abnormal overvoltage, Can cause SPD to lead short circuit to the ground, fuse and circuit breaker can not break fast at this time, SPD fire frequently occurs.
2, when there is a lightning strike, because the fuse and circuit breaker design in the early stage as distribution components used, can not bear the instantaneous energy of lightning current, resulting in device explosion and tripping, SPD failure at this time.
3. When the lightning current passes through the circuit breaker, the Up value (voltage protection level value) is very high, and the SPD cannot play a protective role.
4, the fuse, circuit breaker short circuit analysis ability can not be used in thetransformer into the line, short circuit accident can not be cut off.
