## Summary description

Three-phase miniature circuit breaker EATON HN-B10/3 with a rated current of 10 A and Type B tripping characteristic. Designed for overcurrent protection of electrical circuits in residential and light-commercial installations, it provides protection against short-circuits and overloads for three-phase loads. DIN-rail mountable, suitable for coordination with residual current devices and other protection components.

## Long description

The EATON HN-B10/3 three-phase miniature circuit breaker with a rated current of 10 A and Type B tripping characteristic provides overcurrent protection for three-phase circuits in residential and light-commercial electrical installations. Designed for mounting on a standard DIN rail, this breaker interrupts fault currents caused by overloads or short-circuits and is suitable for coordination with residual current devices and other protection components in distribution panels.
Advantages
The breaker combines compact dimensions with consistent tripping performance according to Type B characteristics, ensuring reliable disconnection of small to moderate fault currents. Its three-pole design allows simultaneous interruption on all phases to maintain system balance. The DIN-rail enclosure and standard connection terminals simplify installation and replacement in distribution boards, while compatibility with downstream protective devices supports modular electrical design.
Suitable for
Protection of three-phase lighting and socket circuits in residential buildings
Overcurrent protection for small commercial or light-industrial loads
Coordination with residual current devices in distribution panels
Replacement or upgrade of existing DIN-rail three-pole protection units
Key specifications
Poles: 3 (three-phase)
Rated current: 10 A
Tripping characteristic: Type B (thermal-magnetic)
Mounting: standard DIN-rail (35 mm)
Connection: screw terminals for line and load conductors
Application: overcurrent protection for short-circuit and overload
How to use
Install the circuit breaker on a compatible DIN-rail inside the distribution board and make sure the supply is disconnected before working on the panel. Connect the three phase conductors to the designated input terminals and the load conductors to the corresponding output terminals, ensuring correct tightening torque for reliable contact. After wiring, switch the breaker to the ON position and verify correct operation by applying normal load; test coordination with residual current devices as required by local installation standards.
Usage recommendations
Select the breaker as part of a coordinated protection scheme: use the Type B tripping characteristic for circuits serving resistive and light inductive loads, and verify that the 10 A rating matches conductor sizing and downstream devices. Periodically inspect terminals for tightness and signs of overheating, and follow local electrical codes for testing and maintenance intervals.
