Eaton xPole Home HNB-C25/1N/003-A RCBO, 2P, 25A, 30mA, Type A

The Eaton xPole Home HNB-C25/1N/003-A is a high-performance 2-pole residual current circuit breaker with overcurrent protection (RCBO), specifically engineered for residential electrical safety. This device integrates both miniature circuit breaker and residual current device functions into a single compact unit, providing comprehensive protection against overloads, short circuits, and dangerous leakage currents. By monitoring the electrical circuit and instantly disconnecting power during fault conditions, it serves as a critical component for modern home distribution boards.

Advantages

This RCBO offers a robust design that enhances electrical system reliability while saving valuable space in the consumer unit. The Type A classification ensures that the device is sensitive to both alternating and pulsating direct residual currents, making it suitable for protecting modern household appliances that utilize electronic components. Its high-quality construction ensures long-term operational stability and consistent performance in demanding residential environments.

Suitable for

• Residential electrical distribution boards
• Protection of lighting and power circuits
• Safety for household appliances with electronic controllers
• Preventing electrical shock and fire hazards

When it may not be suitable

This device is designed for standard residential applications and may not be suitable for industrial environments requiring higher breaking capacities or specific environmental protections. It is not intended for use in DC-only circuits or systems where the leakage current characteristics fall outside the scope of Type A protection.

Key specifications

• Rated current: 25A
• Residual current sensitivity: 30mA
• Poles: 2 (1P+N)
• Type: A
• Function: Combined overcurrent and residual current protection

How to use

The device should be installed by a qualified electrician into a standard DIN-rail distribution board. It is connected in series with the load to be protected, ensuring that both phase and neutral conductors are properly terminated according to the wiring diagram. Once installed, the device can be manually switched on or off using the front lever, and the integrated test button should be used periodically to verify the mechanical and electrical integrity of the tripping mechanism.

What to consider before purchase

• Verify that the 25A rating matches the requirements of your specific circuit
• Ensure the 30mA sensitivity is appropriate for the intended level of personal protection
• Check compatibility with your existing DIN-rail enclosure
• Confirm that Type A protection is required for your specific connected loads

Usage recommendations

Regularly press the test button at least twice a year to ensure the device remains functional and capable of disconnecting the circuit in the event of a fault.
