Eaton xPole Home HNB-C20/1N/003 RCBO, 2P, 20A, 30mA, Type AC

The Eaton xPole Home HNB-C20/1N/003 is a high-quality residual current circuit breaker with overcurrent protection, commonly known as an RCBO. This 2-pole device is engineered to provide comprehensive electrical safety in residential environments by integrating both short-circuit and overload protection with residual current detection in a single compact unit. It is designed to monitor electrical circuits continuously and disconnect the power supply immediately if a fault current is detected, thereby protecting both the electrical installation and the users from potential hazards.

Advantages

This RCBO offers a significant space-saving advantage by combining two essential protective functions into one device, which simplifies the layout of distribution boards. The Type AC sensitivity ensures reliable operation for standard household electrical loads, effectively detecting alternating residual currents. Its robust construction and adherence to safety standards provide long-term reliability and peace of mind for homeowners, ensuring that electrical circuits remain protected against common faults such as overloads and short circuits.

Suitable for

• Residential electrical distribution boards
• Protection of individual lighting and power circuits
• General household appliances and electronics
• Modernizing existing electrical installations

When it may not be suitable

This device is designed specifically for Type AC applications and may not be suitable for circuits where DC components or pulsating DC currents are present, such as those involving certain types of advanced power electronics or EV chargers. In such cases, a Type A or Type B residual current device may be required.

Key specifications

• Rated current: 20A
• Residual current sensitivity: 30mA
• Number of poles: 2 (1P+N)
• Type: AC
• Function: Overload and short-circuit protection combined with residual current detection

How to use

The Eaton RCBO should be installed by a qualified electrician within a standard distribution board on a DIN rail. Once installed, the device operates automatically to monitor the circuit. It features a test button that should be pressed periodically to verify the mechanical functionality of the tripping mechanism. If the device trips, the cause of the fault, such as an overload or a ground fault, must be identified and resolved before resetting the switch to the ON position.

What to consider before purchase

• Verify that the 20A rating matches the requirements of your specific circuit
• Ensure the 30mA sensitivity is appropriate for the intended level of protection
• Check the compatibility of your existing distribution board with DIN rail mounting
• Confirm that the electrical load does not require Type A or Type B protection

Usage recommendations

Regularly test the device using the integrated test button at least every six months to ensure the internal mechanism remains responsive and provides optimal safety for your home electrical system.
