Suitable for DIN-rail mounting in distribution boards and intended for use where fast response to moderate inrush currents is required.

## Long description

EATON HN-B20/1 single-phase 20 A Type B miniature circuit breaker provides overcurrent protection for residential and commercial electrical installations. The device is intended for DIN-rail mounting in distribution boards and combines a compact form factor with a B tripping characteristic that responds quickly to moderate inrush currents while protecting circuits from overloads and short circuits.
Advantages
The single-pole design saves space in distribution panels and simplifies wiring for single-phase circuits. The B tripping curve ensures reliable operation for general-purpose circuits with limited startup currents, reducing nuisance trips compared to more sensitive curves. The breaker’s construction meets industry requirements for mechanical and electrical endurance, offering consistent performance over repeated operations.
Suitable for
 Residential lighting and socket circuits
 Small commercial outlets and general-purpose circuits
 Distribution boards with DIN-rail mounting
 Circuits with low to moderate motor or transformer inrush currents
Key specifications
 Rated current: 20 A
 Poles: single-pole (single-phase)
 Tripping characteristic: Type B (quick response to moderate inrush)
 Function: overcurrent protection (overload and short-circuit)
 Mounting: DIN-rail compatible for distribution boards
How to use
Install the breaker on a standard DIN-rail inside a distribution board, ensuring the panel is de-energized before work begins. Connect the supply conductor to the line terminal and the load conductor to the load terminal according to local wiring regulations and polarity requirements. After secure mechanical and electrical connections are made, restore power and verify correct operation by switching the breaker on and off and checking downstream circuits for continuity and proper function.
Usage recommendations
Use this 20 A Type B breaker for general-purpose single-phase circuits where moderate inrush currents occur, such as lighting, sockets, and small appliances. Coordinate protection with upstream devices and ensure conductor sizes and installation methods match the breaker’s rating and local electrical codes. Periodically inspect terminals for tightness and signs of overheating.
