CHINT – Residual Current Operated Circuit Breaker with Over-current Protection- NB3LEG-C25

Description

The CHINT NB3LEG-C25 Type A Residual Current Operated Circuit Breaker with Over-current Protection (RCBO) is engineered for maximum electrical safety and reliability in residential and commercial installations. Rated at 25A, this single-pole plus neutral (1P+N) circuit breaker provides essential protection against electrical faults, overloads, and short circuits, making it a critical component of modern electrical systems.

This RCBO features a rated residual operating current (I∆n) of ≤ 30 mA, offering vital protection against electric shocks caused by direct contact with live components. Its impressive 6kA short-circuit breaking capacity ensures effective disconnection during fault conditions, safeguarding the entire electrical system.

Designed with advanced tripping capabilities, the NB3LEG-C25 incorporates AC Class and A Class protection, ensuring reliable operation for sinusoidal alternating currents. The AC Class guarantees prompt tripping for both quickly applied and slowly increasing currents, while the A Class allows for response to both sinusoidal alternating residual currents and pulsed DC residual currents, providing a comprehensive safety solution.

With a C Curve (5-10 In) characteristic, this RCBO is particularly well-suited for circuits with inductive and resistive loads that experience low inrush currents. It effectively protects against overloads and short circuits, ensuring the safety of wiring systems, particularly in TN and IT networks. The CHINT NB3LEG-C25 is a robust and dependable choice for enhancing electrical safety and maintaining the integrity of electrical installations.
