Overcurrent circuit breaker 6kA HN-B40/1 194825

Overcurrent circuit breaker for protecting electrical installations

This single-pole circuit breaker from Eaton's xPole Home series, model HN-B40/1, is a reliable solution for protecting electrical circuits in residential and commercial buildings. It provides effective protection against the effects of overloads and short circuits, minimizing the risk of damage to the installation and increasing user safety. Characteristic B makes it particularly well suited for protecting sockets and lighting circuits with resistive loads.

Functionality and installation

The circuit breaker with a rated current of 40A and a short-circuit breaking capacity of 6kA, mounted on a standard DIN TH 35 rail, is easy to install and operate. It has dual terminals – both screw and lift – which facilitates the connection of wires with a cross-section from 1 to 25 mm². Universal power supply (from top or bottom) further simplifies installation. The compact width of 1 module allows for efficient use of space in the distribution board.

Safety and compliance with standards

The circuit breaker meets the requirements of EN 60898-1, ensuring a high level of safety and reliability. Energy limitation class 3 and surge category III guarantee resistance to interference and stable operation in various conditions. Protection class IP20 protects against accidental contact. The rated impulse withstand voltage Uimp is 4kV, which provides additional safety in the event of overvoltage. The circuit breaker also has a contact position indicator (red/green) and the possibility of sealing in the on or off position, which prevents accidental change of the circuit state.

The short-circuit breaking capacity of this circuit breaker is 6kA at 230V and 400V, ensuring effective disconnection of the circuit in the event of a short circuit. Characteristic B makes it ideal for socket and lighting circuits with resistive loads. Dual terminals facilitate the connection of wires or busbars, and mounting on a DIN rail is quick and easy in standard distribution boards. Universal power supply allows connection from the top or bottom, and the compact width of 1 module saves space in the distribution board. The circuit breaker can operate at temperatures from -25°C to +75°C and complies with EN 60898-1, guaranteeing safety and reliability.
