Residual-current circuit breaker (RCBO) EATON xPole Home HNB-C10/1N/003 2P 10A 30mA type AC

EATON xPole Home HNB-C10/1N/003 2P 10A 30mA type AC is a compact residual-current circuit breaker with integrated overcurrent protection designed for residential electrical installations. This RCBO combines earth-leakage detection and breaker trip functions in a single two-pole module, providing both residual-current sensitivity and short-circuit/overload protection for household circuits. The device is rated for a nominal current of 10 A and a residual operating sensitivity of 30 mA (type AC), intended to detect AC sinusoidal leakage currents.

Advantages

The unit integrates residual-current protection and a miniature circuit breaker in one compact housing, saving space in consumer units and simplifying wiring. Its 30 mA sensitivity provides additional safety against electric shock by disconnecting when earth leakage exceeds the threshold, while the built-in overcurrent trip protects wiring and connected equipment from overloads and short circuits. The two-pole design allows reliable disconnection of both phase and neutral conductors in single-phase installations. The product is designed for straightforward mounting on standard DIN rails and for compatibility with common residential distribution boards.

Suitable for

• Protection of sockets and lighting circuits in homes and apartments
• Small single-phase branch circuits requiring both earth-leakage and overcurrent protection
• Retrofit and new-build residential distribution boards with limited module space

Key specifications

• Poles: 2-pole unit for single-phase circuits
• Rated current: 10 A
• Residual sensitivity: 30 mA, type AC (suitable for AC leakage)
• Protection functions: residual-current detection and thermal-magnetic overcurrent trip
• Mounting: DIN-rail compatible compact housing suitable for consumer units
• Intended application: household and light commercial residential circuits, lighting and socket protection

How to use

Install the RCBO into the consumer unit on a standard DIN rail and connect the incoming phase and neutral conductors to the designated terminals following local electrical codes. Ensure correct polarity and tighten terminal screws to the manufacturer’s torque recommendations. Use the device as part of the distribution board to protect individual branch circuits; test the residual-current function after installation by pressing the test button (if present) or following the installer’s verification procedure. After any trip, identify and eliminate fault conditions before resetting the breaker.

Usage recommendations

Use this device in accordance with national wiring regulations and grid operator requirements. Verify compatibility with circuit load and upstream protection devices, and have installation or any replacement performed by a qualified electrician. Periodically test residual-current operation and inspect for signs of damage or corrosion to maintain reliable protection.
