The CHINT NB3LEG-B06 Type A RCBO (1P+N, B Curve, 6A) is a compact safety device that protects against overloads, short circuits, and direct contact, featuring a 6kA short-circuit capacity and 30mA residual current rating. It is ideal for low-power circuits in residential and commercial settings. Available models include 16A, 20A, and 32A variants to suit various applications.
Description
The CHINT NB3LEG-B06 Type A Residual Current Operated Circuit Breaker with Over-current Protection (RCBO) is a highly reliable safety device designed to protect both people and electrical systems in residential, commercial, and light industrial settings. With a rated current of 6A, a B Curve tripping characteristic, and a short-circuit breaking capacity of 6kA, this RCBO is ideal for circuits with low power demands, such as small lighting fixtures and low-energy appliances.
The RCBO features a rated residual operating current (I∆n) of ≤ 30 mA, providing additional protection against electric shock in case of direct contact with live components. This makes it essential for ensuring user safety in sensitive areas.
It is equipped with two key tripping classes:
- AC class, which ensures protection for sinusoidal, alternating currents, whether they are applied rapidly or gradually.
- A class, which extends protection to include pulsed DC residual currents, ensuring comprehensive safety in circuits with more complex electrical loads, such as modern electronics.
The B Curve (3-5 In) tripping characteristic is designed to protect circuits with low inrush currents, such as lighting systems and resistive loads, making it suitable for general-purpose electrical circuits. It also ensures protection for long cable lengths in TN and IT systems, addressing both overloads and short circuits.
The NB3LEG series includes various models with different current ratings to cater to diverse applications:
- NB3LEG-B16 Type A RCBO: 16A version with the same B Curve, ideal for medium-load circuits.
- NB3LEG-B20 Type A RCBO: 20A variant with a C Curve (5-10 In), suitable for circuits with inductive and resistive loads.
- NB3LEG-B32 Type A RCBO: 32A version, designed for high-capacity circuits with greater power demands.
Each model in the NB3LEG series is rated for 6kA short-circuit protection and 30mA residual current protection, ensuring robust safety in a wide range of electrical installations. These RCBOs are designed for easy installation and maintenance, providing essential protection for both users and electrical system
