Overcurrent circuit breaker series 15kA 3-pole FAZ-B40/3 278851

Three-pole overcurrent circuit breaker – reliable installation protection

This FAZ-B40/3 series overcurrent circuit breaker is a key element of every safe and efficient electrical installation. Designed by Eaton, it provides effective protection against overloads and short circuits in AC circuits up to 400V. Its B characteristic makes it ideal for protecting circuits with devices with moderate inrush current, such as lighting or sockets.

This circuit breaker is distinguished by a high breaking capacity of up to 15kA at 400V, which guarantees its reliable operation even in difficult conditions. A width of 3 modules makes it easy to install in standard distribution boards. Solid construction and high quality workmanship ensure long-lasting and trouble-free operation.

Features and application

The FAZ-B40/3 circuit breaker has a wide range of applications in both residential, commercial and industrial construction. It is perfect for protecting:

• Lighting circuits

• Electrical sockets

• Household appliances

• Industrial machines and equipment

• Electrical installations in public buildings

Thanks to the possibility of connecting wires with a cross-section from 1 to 25 mm², the circuit breaker is compatible with various types of wires. The IP20 degree of protection provides protection against accidental contact, which increases safety.

Key benefits for the installer and user

• High breaking capacity (15kA): Ensures effective protection of the installation even with high short-circuit currents.

• B characteristic: Ideal for protecting circuits with devices with moderate inrush current, minimizing the risk of unnecessary tripping.

• Compact dimensions (3 modules): Facilitates installation in tight distribution boards.

• Wide range of wire cross-sections (1-25 mm²): Provides flexibility during installation.

• Durable construction: Guarantees long-lasting and trouble-free operation of the device.

• Compliance with standards: Meets the requirements of EN 60898 and IEC 60947-2 standards, ensuring safety and compliance with regulations.

• Energy limitation class 3: Indicates higher resistance to short-circuit energy, which translates into greater installation safety.
