Circuit breaker 25kA, In=80A, characteristic B. 4-pole. AZ-4-B80 174538

Eaton AZ-4-B80 circuit breaker is a reliable device protecting electrical installations against overloads and short circuits. Designed to operate in AC networks, it offers a rated current of 80A and a high short-circuit breaking capacity – up to 25kA. The four-pole design makes it ideal for protecting polyphase circuits. Characteristic B ensures a quick response to short-circuit currents while allowing for short-term overloads, which is particularly important when connecting devices with electric motors.

This circuit breaker is a solid choice for both professional installers and end-users looking for a safe and effective solution. DIN rail mounting is simple and intuitive, and the compact dimensions (6 modules wide) allow for easy adaptation to existing distribution boards. The device meets stringent safety standards, including overvoltage category III and energy limitation class III, guaranteeing protection of the installation and electrical equipment.

• High short-circuit breaking capacity: 25kA ensures effective protection even in the event of serious failures.
• Characteristic B: optimal for protecting circuits with devices with high inrush current (e.g., motors).
• Four-pole design: allows protection of an entire three-phase circuit or several single-phase circuits.
• Wide operating temperature range: from -25°C to +55°C allows use in various environmental conditions.
• Expandability: compatible with additional auxiliary accessories, such as status indicators or instantaneous release coils.
• Compliance with standards: meets the requirements of IEC 60947-2 and EN 60898, ensuring safety and reliability.

The AZ-4-B80 circuit breaker finds application in a wide range of installations – from residential and commercial buildings to industrial facilities. Its durability and railway approvals make it an ideal solution where particular reliability and protection against the effects of power failures are required. Conductor cross-section from 2.5 mm² to 50 mm² provides flexibility when selecting appropriate power cables. Rated voltage 400V and insulation voltage Ui 440V guarantee safe operation in standard power networks.
