## Summary description

EATON HN-B20/3 is a 3-pole circuit breaker providing overcurrent protection rated at 20 A with a 6 kA breaking capacity. Designed for distribution boards and electrical panels, it interrupts fault currents to protect wiring and connected equipment. Suitable for residential and light-commercial installations where reliable short-circuit and overload protection is required.

## Long description

EATON HN-B20/3 is a 3-pole circuit breaker that provides overcurrent protection for distribution boards and electrical panels. Rated for 20 A per pole with a breaking capacity of 6 kA, this device interrupts fault currents to protect wiring and connected equipment from overloads and short circuits. The compact three-pole design supports protection of three-phase circuits and helps maintain system safety in residential and light-commercial electrical installations.
Advantages
The three-pole construction enables simultaneous disconnection of all phases to prevent dangerous phase-to-phase and phase-to-neutral faults. A 20 A trip rating offers standard overload protection for common branch circuits, while the 6 kA breaking capacity ensures reliable interruption of fault currents within its specified energy range. The breaker is intended for easy integration into standard DIN-rail distribution boards and is compatible with typical panel wiring practices. It provides a consistent electrical performance profile suitable for routine protection needs.
Suitable for
Three-phase branch circuits in residential properties
Light-commercial electrical panels and distribution boards
Protection of motor loads and general-purpose circuits up to 20 A
Retrofit or new installations requiring coordinated short-circuit protection
Key specifications
Poles: 3-pole design for three-phase circuits
Rated current: 20 A per pole
Breaking capacity: 6 kA
Function: Overcurrent protection (overload and short-circuit)
Mounting: DIN-rail compatible for standard electrical panels
How to use
Install the circuit breaker in a compatible distribution board on a standard DIN rail following local electrical codes. Connect line and load conductors to the corresponding terminals for all three phases, ensuring secure torque on terminal screws and proper conductor sizing for 20 A circuits. Verify correct polarity and phase sequence where applicable. After installation, perform insulation and continuity tests and switch the breaker on to confirm normal operation. Use this breaker as part of a coordinated protection scheme alongside upstream and downstream protective devices.
Usage recommendations
Verify that the installation environment and upstream protection are appropriate for a device with a 6 kA breaking capacity. Use correct conductor cross-sections and protective coordination to avoid nuisance trips. Periodically inspect connections for tightness and signs of overheating, and test the protective function after significant electrical work or at recommended maintenance intervals.
