Eaton xPole Home HNB-B10/1N/003 Residual Current Circuit Breaker with Overcurrent Protection, 2P, 10A, B-Curve, 30mA, Type AC

The Eaton xPole Home HNB-B10/1N/003 is a professional-grade residual current circuit breaker with overcurrent protection (RCBO) designed to ensure comprehensive electrical safety in residential environments. This 2-pole device integrates both short-circuit and overload protection with residual current detection into a single, space-saving module, making it an essential component for modern home electrical distribution boards.

Advantages

This RCBO offers a highly reliable solution for protecting electrical circuits against both overcurrent conditions and hazardous leakage currents. By combining two protective functions into one compact unit, it simplifies installation and optimizes space within the distribution cabinet. The B-type tripping characteristic is specifically calibrated for standard residential loads, ensuring stable operation while providing rapid disconnection during fault conditions. Its robust construction and high-quality internal components ensure long-term durability and consistent performance in protecting both people and property from electrical hazards.

Suitable for

• Residential electrical distribution boards
• Protection of lighting circuits
• Protection of standard household socket outlets
• General electrical installations in homes and apartments

This device is not suitable for industrial applications requiring high-power motor starting currents or specialized equipment that generates DC leakage currents, as it is designed specifically for AC-type residual currents. It should not be used in environments where the ambient temperature or humidity levels exceed the manufacturer's specified operating range.

Key specifications

• Rated current: 10A
• Number of poles: 2 (1P+N)
• Tripping characteristic: B-curve
• Residual current sensitivity: 30mA
• Leakage current type: AC

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within the distribution board. Ensure that the supply cables are securely connected to the appropriate terminals, observing the correct polarity for the phase and neutral conductors. After installation, it is recommended to perform a functional test using the integrated test button to verify the correct operation of the residual current mechanism.

What to consider before purchase

• Verify that the 10A rated current is appropriate for the specific circuit load
• Ensure the B-curve characteristic matches the connected appliances
• Confirm that the 30mA sensitivity is required for the intended protection level
• Check available space on the DIN rail in your distribution board

Regularly test the device using the integrated test button every six months to ensure the mechanical tripping mechanism remains functional and provides reliable protection for your home electrical system.
