Description

The CHINT NB3LEG-C06 Type A Residual Current Operated Circuit Breaker with Over-current Protection (RCBO) is an essential safety device designed for protecting electrical circuits in various applications, including residential, commercial, and industrial environments. With a rated current of 6A, this single-pole plus neutral (1P+N) device provides comprehensive protection against electric shock, overloads, and short circuits.

This RCBO features a rated residual operating current (I∆n) of ≤ 30 mA, ensuring additional safety by minimizing the risk of electric shock in the event of direct contact with live conductors. This feature is crucial for maintaining safe environments, especially in areas with high human activity.

Equipped with a C Curve tripping characteristic, the NB3LEG-C06 is engineered to handle circuits with resistive and inductive loads that experience low inrush currents. The device supports a short-circuit breaking capacity of 6kA, making it suitable for both residential and commercial electrical systems.

The tripping mechanism of the RCBO operates under two key classes:

• AC Class: This ensures reliable tripping for sinusoidal alternating currents, whether they are applied rapidly or increase gradually, making it ideal for standard AC systems.
• A Class: This functionality allows the device to trip in response to both sinusoidal alternating residual currents and pulsed DC residual currents, accommodating the diverse needs of modern electrical equipment.

Furthermore, the NB3LEG-C06 is designed with a C Curve (5-10 In) characteristic, which provides effective protection and control against overloads and short circuits. This makes it a suitable choice for circuits requiring protection for resistive and inductive loads. The robust design and multiple protective features make this RCBO a vital component in safeguarding electrical installations, offering peace of mind for users and enhancing overall safety.
