CHINT – Residual Current Operated Circuit Breaker with Over-current Protection- NB3LEG-C16

Description

The CHINT NB3LEG-C16 Type A Residual Current Operated Circuit Breaker with Over-current Protection (RCBO) is a sophisticated electrical safety device designed for protecting circuits in both residential and commercial environments. With a rated current of 16A, this single-pole plus neutral (1P+N) circuit breaker ensures effective protection against electric shock, overloads, and short circuits.

This RCBO features a rated residual operating current (I∆n) of ≤ 30 mA, offering critical protection by ensuring prompt disconnection when direct contact with live parts occurs. This is particularly important for safeguarding users from electrical hazards.

The device has a short-circuit breaking capacity of 6kA, making it highly capable of handling fault currents and enhancing the overall safety of electrical installations. Its C Curve tripping characteristic is specifically designed for circuits with inductive and resistive loads, making it well-suited for environments where low inrush currents may be present.

Equipped with both AC Class and A Class tripping functionalities, the NB3LEG-C16 guarantees effective operation for sinusoidal alternating currents. The AC Class ensures tripping for quickly applied or gradually increasing currents, while the A Class accommodates both sinusoidal alternating residual currents and pulsed DC residual currents, providing versatile protection for various electrical devices.

With a C Curve (5-10 In) characteristic, this RCBO offers robust overload and short-circuit protection, essential for ensuring safety in wiring systems, especially in TN and IT networks. The combination of these features makes the CHINT NB3LEG-C16 a reliable choice for enhancing electrical safety in diverse applications.
