## Summary description

Chint NB310L/3N is an RCBO circuit breaker combining residual current (30 mA) and overcurrent protection in a 3P+N configuration. Rated at C32 characteristic, it protects three-phase circuits with neutral from short circuits, overloads and earth leakage. Suitable for industrial and commercial electrical installations where compact combined protection and selective tripping are required.

## Long description

Chint NB310L/3N is an RCBO circuit breaker that combines residual current protection (30 mA) and overcurrent protection in a 3P+N configuration. With a C32 tripping characteristic, this device is designed to protect three-phase circuits with neutral against short circuits, overloads and earth leakage in industrial and commercial installations. The product is compact and integrates both functions in a single module for simplified wiring and selective protection.
Advantages
The RCBO offers combined residual-current and overcurrent protection in one device, which reduces the number of components on a DIN rail and shortens installation time. The C32 characteristic ensures reliable tripping for moderate inrush currents while maintaining protection against overloads and short circuits. Rated residual current is 30 mA, providing basic protection against electric shock due to earth leakage. The unit is supplied with a 24‑month warranty and has a net weight of approximately 0.07 kg.
Suitable for
Protection of three-phase electrical circuits with neutral (3P+N)
Industrial and commercial electrical panels
Circuits requiring combined RCD and MCB protection in a single device
Installations where compactness and simplified wiring are important

How to use
Install the NB310L/3N on a standard DIN rail within the distribution board according to local electrical codes and the manufacturer's wiring diagrams. Connect the three phase conductors and neutral to the marked terminals and ensure proper tightening of terminals. Use appropriate upstream and downstream protection and follow recommended isolation procedures before working on the circuit. After installation, test the residual-current function and overcurrent tripping to verify correct operation.
Usage recommendations
Use the RCBO in accordance with applicable national regulations and wiring standards. Verify compatibility with the installation's nominal voltage and short-circuit capacity. Perform periodic testing of the residual-current function and visual inspection of connections to maintain reliable protection.
