Why Choose the Chint NB310L-3N-C06 RCBO?
The Chint NB310L-3N-C06 is a compact and reliable 3P+N RCBO (Residual Current Circuit Breaker with Overcurrent Protection) designed to protect three-phase electrical circuits against earth leakage, overload and short circuit faults. By combining residual current protection and overcurrent protection in one device, it helps improve safety while reducing the space required inside distribution boards and control panels.
As part of the Chint NB310L Series, this RCBO features a 6A rated current, C Curve tripping characteristic and Type A residual current protection. It is well suited to circuits with mixed resistive and inductive loads, including control equipment, small machinery supplies and commercial distribution applications.
With a 230/400V AC rated voltage, 30mA residual operating current and 6kA short circuit breaking capacity, the NB310L-3N-C06 provides dependable protection for modern low-voltage electrical installations requiring compact DIN rail mounted RCBO protection.
Key Advantages
- Combined RCBO protection against earth leakage, overload and short circuit faults.
- 6A rated current for low-current three-phase protection circuits.
- C Curve trip characteristic for mixed resistive and inductive loads.

Reliable Protection for Three Phase Circuits
The Chint NB310L-3N-C06 helps protect personnel, cables and connected equipment by disconnecting the circuit when residual current, overload or short circuit conditions are detected. This makes it a practical choice for electricians, panel builders and industrial engineers working with three-phase low-voltage systems.
Its Type A residual current protection makes it suitable for installations containing electronic equipment, power supplies, automation components and control circuits where pulsating DC leakage currents may occur alongside standard AC residual currents.
Typical Applications
- Commercial electrical distribution boards.
- Control panels and automation systems.
- Small three-phase machinery circuits.
- Building services and infrastructure installations.
- Industrial low-voltage power distribution.
- Circuits requiring combined RCBO protection.
