Circuit breaker 25kA, In=40A, characteristic D. 4-pole. AZ-4-D40 174544

Reliable protection of electrical installations – Eaton AZ-4-D40 circuit breaker

This four-pole circuit breaker from Eaton with D characteristic is a solid solution for protecting electrical circuits in residential, commercial and industrial buildings. It provides effective protection against overloads and short circuits, minimizing the risk of damage and fires. The breaking capacity of up to 25kA guarantees safety even in the event of high short-circuit currents.

The AZ-4-D40 circuit breaker is designed for three-phase installations with a voltage of 400V and a rated current of 40A. Its compact design (6 module width) makes it easy to install in electrical distribution boards. Energy limitation class 3 and protection degree IP20 provide additional safety. The D characteristic makes the circuit breaker well suited for impulse loads such as motors or transformers – it reacts more slowly to short-term current surges, avoiding unnecessary tripping of the circuit during device start-up.

Application and benefits:

• Versatile application: ideal for protecting lighting circuits, socket circuits and power lines for high-power devices.
• High breaking capacity: 25kA ensures effective protection even in difficult working conditions.
• D characteristic: optimal for circuits with devices generating surge currents (e.g. motors, transformers).
• Compact dimensions: 6 module width makes it easy to install in standard distribution boards.
• Durable construction: made of high-quality materials, guarantees long life and reliable operation.
• Compliance with standards: meets the requirements of IEC 60947-2 standards, ensuring safety and compliance with regulations.
• Expandability: compatible with additional auxiliary accessories, allowing adaptation to individual installation needs.

The Eaton AZ-4-D40 circuit breaker is an investment in the safety and reliability of your electrical installation. It is a product valued by professionals for its quality of workmanship and ease of installation, and by end-users for the peace of mind resulting from the certain protection of their homes and businesses against the effects of electrical failures.
