Chint NXBLE-63/3P+N C40A Residual Current Operated Circuit Breaker

Chint NXBLE-63/3P+N C40A residual current operated circuit breaker is a product of Chint NXBLE-63 series, mainly used in three-phase four-wire circuits, providing overload, short circuit and leakage protection functions. The specific introduction is as follows:

Basic parameters:

Rated current: 40A.

Number of poles: 3P+N.

Rated voltage: suitable for three-phase circuits of 400V~.

Frequency: 50/60Hz.

Tripping characteristics: C type, suitable for conventional load and distribution line protection.

Rated residual operating current: Commonly 30mA, 100mA, 300mA, etc., depending on the product configuration.

Rated short-circuit breaking capacity: 6000A.

Mechanical life: 20,000 times.

Electrical life: 10,000 times.

Functional features: It has overload protection, short circuit protection and residual current protection functions. When the current in the line exceeds the rated value, a short circuit fault occurs or leakage occurs, it can quickly cut off the circuit to protect the safety of the line and equipment and prevent accidents such as electric shock.

Scope of application: It is suitable for three-phase four-wire circuits in various occasions such as industrial, commercial and civil use, such as factory power distribution systems, commercial building distribution boxes and some residential distribution boxes with high electrical safety requirements, etc. It can provide reliable leakage and overload short-circuit protection for electrical equipment.

Installation method: It usually adopts standard rail installation method, which can be easily installed in the distribution box, which is convenient for construction and maintenance.
