Circuit breaker EATON xPole Home HN-B16/3 3P B 16A 6kA AC

Three-pole mini circuit breaker EATON xPole Home HN-B16/3 provides overcurrent protection for residential and light commercial electrical installations. With a B characteristic and a rated current of 16 A, this 3-pole device combines thermal-magnetic trip behaviour to guard circuits against overloads and short circuits. The breaker is DIN-rail mountable and intended for coordinated protection in three-phase or single-phase systems that require three-pole switching and simultaneous disconnection of all poles.

Advantages

The EATON xPole Home HN-B16/3 offers selective tripping with a B curve suitable for protecting lighting, general socket circuits and small appliance circuits. Its compact modular design saves space in distribution boards and enables straightforward installation on standard DIN rails. The thermal-magnetic mechanism provides reliable response to both long-term overloads and short-circuit events, while the three-pole construction ensures all conductors are disconnected together for safer maintenance and fault isolation.

Suitable for

• Protection of lighting circuits and general-purpose socket circuits in homes
• Small commercial and office distribution boards with low fault levels
• Three-phase circuits requiring simultaneous pole disconnection
• Retrofit or new installations on standard DIN-rail consumer units

Key specifications

• Poles: 3-pole device providing simultaneous disconnection
• Tripping characteristic: B curve (thermal-magnetic)
• Rated current: 16 A
• Breaking capacity: 6 kA (AC)
• Mounting: standard 35 mm DIN-rail
• Application: overcurrent protection for residential and light commercial circuits

How to use

Install the circuit breaker on a standard 35 mm DIN-rail inside the distribution board in accordance with local regulations and wiring practices. Connect line and load conductors to the appropriate terminals, ensuring tight and secure connections and correct conductor sizing for a 16 A circuit. Verify proper coordination with upstream and downstream protection devices and ensure the breaker is accessible for operation and maintenance. Perform insulation and continuity checks before energising the circuit.

Usage recommendations

Use this 3-pole B-characteristic breaker for circuits with resistive and moderately inductive loads such as household lighting and socket outlets. Coordinate with residual-current devices and upstream protective devices where required, and ensure periodic inspection and tightening of terminals to maintain reliable operation.
