Chint NB1L-C06 RCBO featuring a 6 A current rating, C curve characteristic, 30 mA residual current sensitivity, 1P+N configuration and 6 kA breaking capacity.
£65.21
The Chint NB1L-C06 is a compact and reliable residual current operated circuit breaker with over-current protection (RCBO) designed for residential, commercial and light industrial electrical installations. As part of the Chint NB1L series, it combines earth leakage protection, overload protection and short-circuit protection within a single modular device.
Featuring a 1P+N configuration, this RCBO is suitable for single-phase circuits requiring comprehensive electrical protection. Its C curve tripping characteristic is designed for circuits with moderate inrush currents, while the 30 mA residual current sensitivity provides additional protection against electric shock and earth leakage faults.
With a rated current of 6 A, a rated voltage of 230 / 240 V AC and a short-circuit breaking capacity of 6 kA, the NB1L-C06 is ideal for lighting circuits, control circuits, auxiliary supplies and small inductive loads. Its compact DIN rail mounting design enables straightforward installation in consumer units and distribution boards.
The Chint NB1L-C06 combines the functions of a miniature circuit breaker and residual current device within one compact unit. It automatically disconnects the circuit during overloads, short circuits or earth leakage faults, helping protect both people and electrical installations.
Using an RCBO on individual circuits helps reduce unnecessary disruption, as faults are isolated to the affected circuit rather than disconnecting multiple circuits protected by a shared RCD.

The Chint NB1L-C06 protects single-phase circuits against overloads, short circuits and earth leakage faults.
The NB1L-C06 has a rated current of 6 A.
A C curve RCBO trips between 5 and 10 times its rated current, making it suitable for circuits with moderate inrush currents from motors, transformers and similar equipment.
This RCBO provides a 30 mA residual operating current sensitivity for additional personal protection.
Yes. The device is designed for quick installation onto standard 35 mm DIN rails within consumer units and distribution boards.
Chint NB1L RCBOs are widely used by electricians, panel builders and maintenance engineers to provide dependable combined over-current and residual current protection across residential and commercial installations.
