WebFeb 11, 2024 · kA rating of an MCB or an MCCB is the maximum current it can safely interrupt in case of a short circuit. 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. For example, if the MCB is rated at 10kA, it means ... WebNov 25, 2024 · Meanwhile, the RCCB measures the level of current which goes in and out of a device. Any difference between the two levels may be an indication of an earth leakage current. When the RCCB detects this difference, it induces a circuit breaker trip to prevent electrical shocks. Normally, the rating of an RCCB is between 10 mA and 30 mA.
