Product information

Description

EATON HN-B40/1 is a single-pole circuit breaker rated for 40 A with a short-circuit breaking capacity of 6 kA. It is designed for overcurrent protection in low-voltage electrical installations, combining thermal and magnetic tripping characteristics to protect against overloads and short circuits. The device is intended for installation in distribution boards to safeguard individual circuits, appliances and wiring against excessive current.

Advantages

The EATON HN-B40/1 offers precise thermal-magnetic protection that responds to both prolonged overloads and instantaneous short-circuit conditions. Its single-pole format saves space in modular distribution panels and simplifies wiring for single-phase circuits. The unit conforms to common installation practices for residential and light commercial electrical systems, enabling reliable circuit interruption and straightforward replacement or upgrade of protective devices.

Suitable for

Protection of lighting circuits in homes and small commercial premises
Protection of socket circuits and individual appliances
Use in single-phase distribution boards and consumer units
Replacement or upgrade of existing 1-pole circuit breakers

Key specifications

Poles: 1 (single-pole)
Rated current: 40 A
Breaking capacity: 6 kA (6000 A)
Tripping type: thermal-magnetic (overload and short-circuit protection)
Designed for low-voltage electrical installations
Modular format for DIN-rail distribution boards

How to use

Install the breaker in the appropriate slot of a compatible distribution board according to local electrical codes and the panel manufacturer's instructions. Connect the incoming phase conductor to the breaker terminal and the outgoing circuit conductor to the load terminal, ensuring correct torque on terminal screws and secure DIN-rail mounting. After installation, switch the breaker to the ON position and verify circuit continuity and proper function with suitable testing equipment. For safety, disconnect supply power before performing installation or service.

Usage recommendations

Use the EATON HN-B40/1 in circuits where 40 A protection is required and where a 6 kA breaking capacity is sufficient for the installation's prospective short-circuit current. Verify coordination with upstream protection devices and confirm compatibility with the distribution board's busbar and terminal ratings. Have installations and replacements carried out or inspected by a qualified electrician in accordance with applicable standards and regulations.
