What is the number of small circuit breakers indicate, and the small circuit breaker parameter analysis

Small circuit breakers are widely used, which is the most common circuit breaker. The small circuit breaker panel will be marked with detailed parameters, which is an important reference for our purchase.

Some netizens ask about 4000 on the small circuit breaker, I will talk more about it here.What is the number of small circuit breakers indicate, and the small circuit breaker parameter analysis

Small circuit breaker parameters

Small circuit breaker parameters有这几个.What is the number of small circuit breakers indicate, and the small circuit breaker parameter analysis

  • Instantaneous trip characteristics and rated current:

E.gC16Tripping characteristics areC-typeRated current is16. The rated current (in) is common with 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A, and the like. Tripping features are commonC-typewithD型,Difference to see Xiaobian’s previous article has a presentation, click to view the article “小型Circuit breakerC-typewithD型有什么区别,都是怎么选用的.

  • Rated working voltage:

交流230V/400V(1P)、400V(2P,3P,4P).

  • Rated short-circuit breaking capability ICN:

6000 of the small circuit breaker is markedRated short-circuit breaking capability ICN:.

Circuit breakerRated short-circuit breaking capability ICN:include,Rated ultimate short circuit breaking capability ICUwithRated short-circuit breaking capability ICS..These two differences can click to read “What is the parameters on the circuit breaker nameplate?“.

Only do it in small circuit breakersRated short-circuit breaking capability ICS.experiment of.所以小型断路器上的6000或4500就是小型断路器能够可靠瞬间切断的最大短路电流.在切断该瞬间短路电流后,断路器仍可以继续使用.超过这个电流的短路小型断路器就不能再继续可靠使用了.(国标《家用及类似场所用断路器”GB10963(等效采用IECB60898)规定断路器应进行Rated ultimate short circuit breaking capability ICUwithRated short-circuit breaking capability ICS.试验.当Icu≤6000A时,Icu=Ics,故只需作Ics试验.)
