CHINT – Residual Current Operated Circuit Breaker with Over-current Protection- NB3LEG-C10

Description

The CHINT NB3LEG-C10 Type A Residual Current Operated Circuit Breaker with Over-current Protection (RCBO) is a vital electrical safety device designed to protect circuits in residential, commercial, and industrial applications. With a rated current of 10A, this single-pole plus neutral (1P+N) circuit breaker effectively safeguards against electric shock, overloads, and short circuits.

Featuring a rated residual operating current (I∆n) of ≤ 30 mA, the NB3LEG-C10 offers enhanced protection by ensuring quick disconnection in the event of direct contact with live electrical parts. This feature is essential for maintaining safety in environments where human exposure to electrical hazards is possible.

The device is equipped with a 6kA short-circuit breaking capacity, making it capable of handling high fault currents and contributing to the overall safety of electrical installations. The C Curve tripping characteristic is particularly well-suited for circuits with inductive and resistive loads that may experience low inrush currents, providing reliable operation without nuisance tripping.

This RCBO incorporates both AC Class and A Class tripping functionalities. The AC Class ensures effective tripping for sinusoidal alternating currents, whether they are applied rapidly or increase gradually. Meanwhile, the A Class capability allows for tripping in response to both sinusoidal alternating residual currents and pulsed DC residual currents, addressing the needs of modern electrical devices.

Designed with a C Curve (5-10 In) characteristic, the NB3LEG-C10 provides robust protection and control against overloads and short circuits, ensuring safety in wiring systems, especially in TN and IT networks. This combination of features makes the CHINT NB3LEG-C10 a dependable choice for those looking to enhance electrical safety in various applications.
