Description

The CHINT NB3LEG-C32 Type A Residual Current Operated Circuit Breaker with Over-current Protection (RCBO) is an advanced electrical safety device designed for effective protection in both residential and commercial electrical installations. Rated at 32A, this single-pole plus neutral (1P+N) circuit breaker ensures robust protection against electrical faults, including overloads and short circuits.

This RCBO features a rated residual operating current (I∆n) of ≤ 30 mA, providing essential safety measures against electric shocks resulting from direct contact with live electrical components. Its 6kA short-circuit breaking capacity guarantees reliable disconnection during fault conditions, enhancing the overall safety of electrical systems.

The NB3LEG-C32 is equipped with advanced tripping mechanisms, featuring both AC Class and A Class protections. The AC Class ensures prompt tripping for sinusoidal alternating currents, whether they are applied quickly or gradually increase. The A Class tripping ensures reliable response to both sinusoidal alternating residual currents and pulsed DC residual currents, offering comprehensive protection for a wide range of electrical applications.

With a C Curve characteristic (5-10 In), this RCBO is specifically tailored for circuits that include resistive and inductive loads experiencing low inrush currents. It provides effective protection against overloads and short circuits, ensuring the safety of wiring systems, particularly in TN and IT systems. The CHINT NB3LEG-C32 is a reliable and essential component for enhancing electrical safety and maintaining the integrity of electrical installations.
