Circuit breaker 3P EATON xPole Home HN-B10/3 10A B-characteristic 6 kA AC

The EATON xPole Home HN-B10/3 is a three-pole miniature circuit breaker rated for 10 A with a B tripping characteristic and 6 kA AC breaking capacity. Engineered for DIN-rail installation in residential and light-commercial distribution boards, this three-pole breaker provides coordinated protection for three-phase circuits and common neutral arrangements. It is designed to detect and interrupt overloads and short circuits to maintain safety and reliability in lighting, socket circuits and small appliance supplies.

Advantages

The device combines a compact DIN-rail form factor with a B-type instantaneous characteristic, making it suitable for circuits with predominantly resistive loads and moderate inrush currents. Its 6 kA AC breaking capacity meets typical domestic and light-commercial requirements, ensuring reliable clearing of short-circuit faults. The three-pole design simplifies protection of multi-phase feeders and offers consistent trip behaviour across phases for balanced circuit safeguarding.

Suitable for

• Three-phase lighting circuits in homes and small commercial premises
• Socket and general-purpose circuits with 10 A demand per phase
• Protection of small motors and appliances with low inrush currents
• DIN-rail distribution boards and sub-distribution panels

Key specifications

• Poles: 3-pole miniature circuit breaker
• Rated current: 10 A
• Tripping characteristic: B (instantaneous trip for moderate inrush)
• Breaking capacity: 6 kA AC
• Mounting: DIN-rail (standard distribution board installation)
• Application: residential and light-commercial circuit protection

How to use

Install the breaker on a standard DIN-rail inside the distribution board following local electrical codes and the manufacturer's installation instructions. Connect the three phase conductors to the line terminals and the load conductors to the outgoing terminals, ensuring correct torque on terminal screws and proper conductor preparation. Verify circuit continuity and perform insulation and polarity checks before energising. Switch the breaker to the ON position to place the circuit under protection and test the installation by switching connected loads while monitoring for correct operation.

Usage recommendations

Select the EATON xPole Home HN-B10/3 when protecting three-phase circuits with predominantly resistive loads or where moderate inrush currents are expected. Coordinate this breaker with upstream and downstream protective devices to achieve selectivity and avoid nuisance trips. Ensure installation and testing are performed by a qualified electrician and comply with applicable local regulations and standards.
