Chint NXBLE-63/3P+N C63A Residual Current Operated Circuit Breaker

Chint NXBLE-63/3P+N C63A Circuit Breaker is a residual current operated circuit breaker from Chint, mainly used in three-phase four-wire circuits, providing overload, short circuit and leakage protection functions, as follows:

Rated current: 63A, that is, the maximum current allowed to pass through the circuit breaker when it is working normally is 63A.

Rated residual operating current: 30mA is common, and other specifications are also available. When the leakage current in the circuit reaches the set value, the circuit breaker will quickly trip and cut off the circuit to play a role in leakage protection.

Rated voltage: 400VAC, suitable for AC circuits with a rated voltage of 400V.

Frequency: 50/60Hz, can work stably in 50 Hz or 60 Hz AC power systems.

Tripping characteristics: C-type tripping characteristics, suitable for conventional load and distribution line protection, can trip according to a specific time-current curve when the current suddenly increases.

Mechanical life and electrical life: The mechanical life is 20,000 times and the electrical life is 10,000 times, with high reliability and durability.

Rated short-circuit breaking capacity: 6kA, which means that the maximum short-circuit current that the circuit breaker can safely cut off is 6000A, which can quickly cut off the current when a short-circuit fault occurs in the circuit to protect the circuit and equipment.

Rated impulse withstand voltage: 4kV, which can withstand a certain intensity of voltage shock, enhancing the stability and safety of the product in a complex electrical environment.

Leakage protection type: AC type.

Leakage release type: electronic.
