Why Choose the Chint NB1L-C32 RCBO?
The Chint NB1L-C32 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 32 A, a rated voltage of 230 / 240 V AC and a short-circuit breaking capacity of 6 kA, the NB1L-C32 is ideal for socket outlet circuits, radial circuits, small motors and general-purpose final circuits. Its compact DIN rail mounting design enables straightforward installation in consumer units and distribution boards.
Key Advantages
- Compact RCBO combining RCD and MCB protection.
- 32 A rated current for higher rated final circuits.
- 30 mA residual current sensitivity for additional personal protection.
- C curve characteristic for circuits with moderate inrush currents.
- 6 kA short-circuit breaking capacity for dependable fault protection.
- Quick DIN rail installation in consumer units and distribution boards.

Combined Circuit and Earth Leakage Protection
The Chint NB1L-C32 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.
Typical Applications
- Consumer units and distribution boards.
- Socket outlet circuits.
- Radial circuits.
- Residential electrical installations.
- Commercial buildings.
- Small motors and inductive loads.
