Chint NXBLE-63/4P C40A Residual Current Operated Circuit Breaker

Chint NXBLE-63/4P C40A Circuit Breaker is a 4-pole residual current operated circuit breaker from Chint with a rated current of 40A. It has overload, short circuit and leakage protection functions and is suitable for three-phase four-wire circuits. The specific introduction is as follows:

Technical parameters:

Rated voltage: 400V~.

Frequency: 50/60Hz.

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

Rated residual operating current: Common specifications include 30mA, 50mA, etc., depending on the product configuration.

Rated short-circuit breaking capacity: 6000A.

Mechanical life: 20,000 times.

Electrical life: 10,000 times.

Rated impulse withstand voltage: 4kV.

Functional features: This circuit breaker combines overload, short-circuit protection and leakage protection functions. When the current in the circuit exceeds the rated value of 40A, a short circuit fault occurs, or leakage occurs, the circuit can be quickly cut off to effectively protect the safety of the circuit and equipment and prevent accidents such as electric shock. At the same time, it may have a visual trip indication, which is convenient for users to intuitively judge whether the circuit breaker is in action. There is also a test button to regularly test whether the leakage protection function is normal.

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, large residential distribution boxes, etc., which can provide reliable leakage and overload short-circuit protection for electrical equipment.

Installation method: It adopts a 35mm standard rail installation method, which can be easily installed in the distribution box, which is convenient for construction and maintenance, and is generally modular in design, which is convenient for replacement.

Compliance with standards: It complies with relevant standards such as GB/T 16917.1, IEC 61009-1, and has obtained the national mandatory CCC certification. The manufacturer has passed ISO9001, ISO14001, OHSAS18001 and other management system certifications.
