Overcurrent circuit breaker 25 kA, In= 80 A, characteristic C, 3-pole AZ AZ-3-C80 211801

Overcurrent circuit breaker – reliable protection for electrical installations

This three-pole overcurrent circuit breaker from Eaton, with a rated current of 80A and C characteristic, is a key element ensuring safety in every electrical installation. The rated short-circuit breaking capacity of 25 kA guarantees an effective response in the event of overloads and short circuits, protecting both devices and the installation.

The AZ-3-C80 model is designed to protect circuits against the effects of overcurrents, ensuring continuity of supply and minimizing the risk of failure.

Characteristics and application

The circuit breaker is characterized by a C characteristic, which means that it allows for short-term current overloads without tripping. This is particularly important when connecting devices with electric motors or other loads with high starting current – such as pumps or compressors. This avoids unnecessary tripping of the circuit when starting these devices. The rated voltage of 400V and a wide range of permissible conductor cross-sections (2.5 – 50 mm²) make the circuit breaker universal and can be used in various installations – both in residential and commercial buildings. Energy limitation class 3 and surge category 3 confirm high resistance to interference and ensure stable operation in difficult conditions.

Key features and benefits

• High short-circuit breaking capacity (25 kA): ensures a quick and effective response in the event of a failure, minimizing damage to the installation and connected devices.
• C characteristic: ideal for protecting circuits with loads with high starting current, prevents unnecessary tripping of the circuit breaker.
• Wide range of permissible conductor cross-sections (2.5 – 50 mm²): allows connection of cables of different thicknesses, increasing the flexibility of the installation.
• Protection degree IP20: provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.
• Mounting on TH35 rail: standard mounting simplifies installation and replacement of the circuit breaker in existing switchboards.
• Compliance with IEC 60947-2 standards: guarantee of safety and reliability of the device confirmed by certificates of compliance with applicable standards.
• Ambient temperature in operating conditions from -25°C to 55°C: enables operation in a wide temperature range, which is important for outdoor or unheated applications.
• Width 4.5 modules: compact dimensions allow for efficient use of space in the switchboard.

The Eaton AZ-3-C80 circuit breaker is a solid and reliable solution for professionals and demanding end-users who value the safety and durability of their electrical installation.
