## Summary description

RCBO EATON HNB-B16/1N/003 combines overcurrent protection and residual-current (earth-leakage) protection in a single module. Rated for 16 A with B tripping characteristic, 30 mA AC residual current sensitivity, single pole plus neutral (1P+N) configuration and 6 kA breaking capacity. Suitable for protecting circuits and persons in residential or light commercial installations where combined short-circuit, overload and leakage protection is required.

## Long description

The residual-current circuit breaker RCBO EATON HNB-B16/1N/003 B 16A 30mA AC 1P+N 6kA combines overcurrent interruption and earth-leakage detection in a single compact module. Designed for installation in residential and light commercial distribution boards, this RCBO provides thermal-magnetic short-circuit and overload protection with a B tripping characteristic and simultaneous residual-current protection with 30 mA AC sensitivity. The device is a single pole plus neutral (1P+N) unit with a rated current of 16 A and an electricity fault breaking capacity suitable for typical low-voltage installations.
Advantages
This RCBO integrates two protection functions—short-circuit/overload interruption and residual-current (earth-leakage) detection—saving space in the distribution board and simplifying wiring. The B tripping curve offers reliable protection for circuits with moderate inrush currents such as lighting and general-purpose outlets. The 30 mA residual-current sensitivity provides personal protection against electric shock, while the compact 1P+N form factor reduces the number of modules required. The device is built to meet industry performance levels for common low-voltage installations.
Suitable for
Protection of lighting circuits in residential and small commercial premises
General power outlets and socket circuits
Circuits requiring combined overload, short-circuit and earth-leakage protection
Key specifications
Rated current: 16 A
Tripping characteristic: B curve (thermal-magnetic)
Residual-current sensitivity: 30 mA, AC type
Poles: single pole plus neutral (1P+N)
Breaking capacity: 6 kA
How to use
Install the RCBO in a compatible DIN-rail distribution board according to local wiring regulations and the manufacturer's installation instructions. Connect the phase conductor to the live terminal and the neutral conductor to the neutral terminal; ensure proper tightening torques for terminals. Use the device to protect the designated circuit by placing it in series with the load; test the residual-current function after installation using a test button or an approved testing device. If the unit trips, identify and correct the fault before resetting.
Usage recommendations
Use this RCBO for individual circuit protection where both overcurrent and earth-leakage safety are required. Perform periodic testing of the residual-current function and visual inspections as part of routine electrical maintenance. Replace units that show physical damage or fail functional tests.
