Why Choose the Chint NB310L-2P-B06 RCBO?
The Chint NB310L-2P-B06 is a reliable Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide combined protection against earth leakage, overloads and short circuits. It is suitable for low-voltage electrical installations where both personnel protection and circuit protection are required in a single compact device.
As part of the Chint NB310L RCBO series, this unit combines residual current protection with magnetic overcurrent protection, helping protect cables, equipment and people from electrical fault conditions. Its 2-pole configuration provides switching of both line and neutral, making it suitable for single-phase distribution boards and consumer units.
With a rated current of 6 A, B curve tripping characteristic, Type A residual current protection and a 30 mA residual operating current, the NB310L-2P-B06 is ideal for lighting circuits and sensitive final circuits with lower inrush currents. Its 6 kA breaking capacity supports dependable protection in residential, commercial and light industrial installations.

Reliable Protection for Low-Load Final Circuits
RCBOs such as the Chint NB310L-2P-B06 are used to protect electrical circuits from both residual current faults and overcurrent conditions. This helps reduce the risk of electric shock, cable overheating and damage caused by overloads or short circuits.
The B curve characteristic makes this model suitable for circuits with relatively low starting currents, such as lighting circuits, small control circuits and sensitive final circuits. Its Type A residual current protection provides detection of both sinusoidal AC and pulsating DC residual currents, making it suitable for many modern electrical loads.
Typical Applications
- Residential consumer units.
- Commercial distribution boards.
- Lighting circuits.
- Small final circuits.
- Control circuits with low inrush current.
- Light industrial electrical panels.
