Eaton xPole Home HNB-B16/1N/003-A Residual Current Circuit Breaker with Overcurrent Protection, 2P, 16A, B-Curve, 30mA, Type A

The Eaton xPole Home HNB-B16/1N/003-A is a professional-grade residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive safety for residential electrical circuits. This 2-pole device integrates both short-circuit and overload protection with residual current detection in a single compact unit, making it an essential component for modern home distribution boards. By combining these functions, it effectively monitors electrical flow and instantly disconnects the circuit in the event of a fault, protecting both the wiring infrastructure and the connected appliances.

Advantages

The primary advantage of this Eaton RCBO is its ability to combine two critical safety functions into one space-saving module, which simplifies installation and reduces the amount of wiring required in the distribution cabinet. The Type A sensitivity ensures that the device can detect both AC and pulsating DC residual currents, offering a higher level of protection compared to standard AC-type breakers. Its B-curve tripping characteristic is specifically optimized for residential applications, providing a balanced response to standard household loads while preventing nuisance tripping during normal operation.

Suitable for

• Residential electrical distribution boards
• Protection of lighting and socket circuits
• Safeguarding household appliances and electronic devices
• New installations and electrical system upgrades

When it may not be suitable

This device is not intended for industrial environments with high-power machinery or equipment that generates significant harmonic distortion. It is also not suitable for circuits requiring a different tripping curve, such as C or D, which are necessary for devices with high inrush currents like large motors or industrial compressors.

Key specifications

• Rated current: 16A
• Tripping characteristic: B-curve
• Residual current sensitivity: 30mA
• Device type: Type A
• Number of poles: 2P (1P+N)

How to use

The Eaton xPole Home RCBO should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting on a standard DIN rail within a distribution board. Ensure that the supply cables are connected to the designated terminals and that the neutral conductor is correctly identified and wired. After installation, the device should be tested using the integrated test button to verify its mechanical and electrical functionality.

What to consider before purchase

• Verify that the 16A rating matches the requirements of your circuit wiring
• Ensure the 30mA sensitivity is appropriate for the intended level of personal protection
• Confirm that the DIN rail space is sufficient for a 2-pole device
• Check if your local regulations require Type A protection for specific appliance types

Usage recommendations

Regularly test the device using the test button at least twice a year to ensure the internal mechanism remains operational. If the breaker trips, investigate the cause of the fault before resetting the switch.
