Household Distribution Box Used 20ka 4 Poles Surge Special Circuit Breaker up Protector 20KA Discharge Current Capability
Surge backup protector (SCB) Product Characteristics :
20KA(8/20us) discharge current capability
4poles 72mm tiny volume, one wrench each pole
Secondary distribution cabinet preferred, especially suitable for household distribution box
Lightning current shock continues to open, lightning protection continues to be effective, T1 level up to 25 Ka
Abnormal power network, power frequency current 3A speed off, SPD does not fire
Residual low pressure, equivalent fuse, more safe protection equipment
Standard guide rail installation:35mm
dopt high-energy contact, long service life;
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;
Complete specifications can meet T1, T2, T3 SPD matching

How SCB works
SPD backup protection device requires constant lightning flow to maintain an effective state; When the SPD is degraded or the power supply is abnormal, the power frequency leakage current occurs and reaches the fire boundary value of 5A
The fuse, circuit breaker VS SCB:
| SCB | Fuses and circuit breakers |
| SPD special backup protector, intelligent identification of lightning current and power frequency current. | Used for low voltage distribution leakage load, short circuit protection. |
| Surge impact is not tripped, residual low, lightning protection equipment continued effective | wrong action by surge, poor lightning protection performance, generally only 20KA, the equipment lost lightning protection and damage. |
| When the short circuit current >3A flowing through SPD is broken in 0.1-0.3s,SPD will not catch fire | Small current (several amperes) does not operate, its action value is 5~10 times its own rating,SPD fire combustion. |
| Power frequency short circuit breaking ability | Power frequency short circuit breaking capacity is insufficient, after the SPD fire, the short circuit arc continued to burn, causing a major fire accident. |
