Chint is a brand that manufactures electrical equipment, including circuit breakers.
- 6kA: This refers to the breaking capacity of the circuit breaker, indicating its ability to interrupt a fault current of up to 6,000 Amperes.
- 1P+N: This indicates the number of poles in the circuit breaker. “1P” stands for one pole, and “N” represents the neutral pole. In this case, it suggests a single-phase circuit with one live wire and one neutral wire.
- 63A: This indicates the rated current of the circuit breaker, which is 63 Amperes. It specifies the maximum continuous current the breaker can handle.
- Earth leakage 30mA: This refers to the sensitivity of the circuit breaker’s residual current device (RCD) or ground fault circuit interrupter (GFCI). A 30mA (milliampere) rating means that the device will trip and interrupt the circuit if a ground fault or leakage current of 30mA or above is detected.
The Chint 6kA 1P+N 63A circuit breaker you mentioned is a single-phase breaker with a maximum current rating of 63 Amperes. It is equipped with an earth leakage protection device that will trip if a leakage current of 30mA or higher is detected.
