Eaton xPole Home HNB-C25/1N/003 Residual Current Circuit Breaker with Overcurrent Protection, 2P, 25A, 30mA, Type AC

The Eaton xPole Home HNB-C25/1N/003 is a high-quality 2-pole residual current circuit breaker with overcurrent protection, commonly known as an RCBO. This device is specifically engineered for residential electrical installations, offering a comprehensive safety solution by combining short-circuit protection, overload protection, and residual current detection in a single compact unit. It is designed to monitor electrical circuits effectively, ensuring that any dangerous leakage currents are detected and interrupted promptly to protect both the electrical infrastructure and the users.

Advantages

The primary advantage of this Eaton RCBO is its ability to provide dual-layer protection within a single module, which significantly saves space in modern consumer units. By integrating both overcurrent and residual current functions, it simplifies the wiring process and reduces the number of components required for circuit safety. The device is built to high manufacturing standards, ensuring long-term reliability and consistent performance in domestic environments. Its Type AC classification makes it suitable for standard household applications where alternating current leakage protection is required.

Suitable for

• Residential electrical distribution boards
• Protection of individual lighting and power circuits
• Preventing electrical shocks in home environments
• Safeguarding household appliances against overloads and short circuits

When it may not be suitable

This device is designed for Type AC applications and may not be appropriate for circuits containing electronic equipment that produces pulsating DC components, where a Type A or Type B device would be required. It is intended for standard residential use and is not suitable for industrial environments with high-frequency interference or specific heavy-duty machinery requirements.

Key specifications

• Number of poles: 2 (1P+N)
• Rated current: 25A
• Residual current sensitivity: 30mA
• Device type: AC
• Function: Overcurrent and residual current protection

How to use

The Eaton RCBO should be installed by a qualified electrician into a standard DIN-rail distribution board. The device is mounted by snapping it onto the rail and connecting the supply and load cables to the designated terminals. Once installed, the circuit breaker can be manually switched on or off using the front toggle. It is recommended to perform a functional test using the integrated test button periodically to ensure the tripping mechanism remains operational.

What to consider before purchase

• Verify that the 25A rated current matches the requirements of your specific circuit
• Ensure the 30mA sensitivity is appropriate for the intended level of personal protection
• Confirm that your distribution board has sufficient space for a 2-pole module
• Check if your local electrical regulations permit the use of Type AC devices for your specific installation

Usage recommendations

Regularly test the device using the built-in test button at least twice a year to verify the integrity of the protection mechanism. If the device trips frequently, inspect the circuit for potential faults or overloaded appliances before resetting.
