Tips: The ultimate short-circuit breaking capacity and operating short-circuit breaking capacity of miniature circuit breakers
- Ultimate short-circuit breaking capacity (Icu): According to the conditions specified in the prescribed test procedures, excluding the breaking capacity of the circuit breaker to continue to carry its rated current capacity, in plain language, it means that this circuit breaker has a short-circuit fault when in use The expected maximum short-circuit current can be interrupted at a time without causing damage to the line, and the line is protected, but the micro-break is damaged or burned out and can no longer be used.
- Operating short-circuit breaking capacity (Ics): According to the conditions specified in the prescribed test procedures, including the breaking capacity of the circuit breaker to continue to carry its rated current capacity, in plain language, it means that when the circuit breaker is in use, the line has a short circuit fault It can break not more than a certain proportion of the expected maximum short-circuit current at a time without causing damage to the line. The line is protected, and the circuit breaker itself can still be used without damage.
6 amp 1 pole MCB miniature circuit breaker provides overload and short circuit protection for conductors, with 6 amp current rating, used in AC 50Hz, 230/400V with a 6 kA short circuit withstand rating.
