KEPCO circuit breaker value

If the current goes beyond this value, the circuit breaker could be damaged. kA rating is known as the short circuit withstand capacity or ultimate breaking capacity of a circuit breaker. It is denoted by Icu. For example, if the MCB is rated at 10kA, it means that the MCB can safely break the circuits during short circuit unless until the ...

  • Role of X/R Ratio in Circuit Breaker Short Circuit Duty

    Jan 30, 2015The circuit breaker nameplate may only indicate short circuit symmetrical current which could lead to incorrect assessment if the assumed X/R ratio is less than the test X/R ratio. However, circuit breakers are typically tested at certain X/R ratio, depending on type of application. If the test X/R ratio of the breaker is not available from the

  • How to Determine the Load Capacity of Your Circuit Breaker

    This rating is labeled on the breaker itself. The standard for most household circuits are rated either 15 amps or 20 amps. An important note to remember is that circuit breakers can only handle about 80% of their overall amperage. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.
