Chint NXBLE-63/3P+N C20A Residual Current Operated Circuit Breaker

Chint NXBLE-63/3P+N C20A Circuit Breaker is a residual current operated circuit breaker from Chint, mainly used in three-phase four-wire circuits, with overload, short circuit and leakage protection functions. The specific parameters are as follows:

Rated current: 20A, that is, the maximum current allowed to pass during normal operation is 20A.

Rated residual operating current: There are various specifications available, such as 0.03A, 0.05A, 0.075A, 0.1A, 0.3A, etc. 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: 400V~, suitable for AC circuits with a rated voltage of 400V.

Frequency: 50/60Hz, can work stably in 50 Hz or 60 Hz AC power supply 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: 20,000 times.

Electrical life: 10,000 times.

Rated short-circuit breaking capacity: 6000A, 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, can withstand a certain intensity of voltage shock, enhance the stability and safety of the product in complex electrical environments.
