Overcurrent circuit breaker 25kA, In=25A, characteristic B. 4-pole. AZ-4-B25 174533

Overcurrent circuit breaker – reliable protection for electrical installations

This four-pole overcurrent circuit breaker from Eaton's AZ series, with a rated current of 25A and B characteristic, is a key element ensuring safety in every electrical installation. The short-circuit breaking capacity of 25kA guarantees effective protection against the effects of overloads and short circuits, minimizing the risk of damage and fires. Made of high-quality materials, this circuit breaker is characterized by durability and reliability, making it an ideal solution for both professional installers and end users.

Features and application

The AZ-4-B25 circuit breaker is designed to protect electrical circuits in residential, commercial buildings and industrial installations. The B characteristic provides a quick response to an increase in short-circuit current, while allowing for short-term overloads without unnecessary tripping – which is particularly important when connecting devices with electric motors or other loads with high inrush current. The width of 6 modules makes it easy to install in standard distribution boards. The rated impulse withstand voltage of 4kV increases resistance to overvoltage.

Advantages and benefits

• High short-circuit breaking capacity (25kA): ensures effective protection against serious failures and damage to the installation.
• B characteristic: ideal for protecting circuits with loads with high inrush current, minimizes the risk of false tripping.
• 4 poles: allows for comprehensive protection of three-phase electrical circuits and the neutral conductor.
• Mounting on TH35 rail: standard mounting simplifies integration with existing distribution boards.
• Protection class IP20: provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.
• Expandability: compatibility with additional accessories allows you to adapt the circuit breaker's functionality to individual needs.
• Compliance with standards: the product meets the stringent safety standards of IEC 60947-2, guaranteeing a high level of reliability and safety.
• Railway approvals: confirm the high quality and reliability of the product in demanding operating conditions.
• Energy limitation class 3: provides adequate protection in the event of an electric arc.

Eaton AZ series circuit breakers are a proven choice for demanding users who value safety, reliability and durability. Thanks to its solid construction and advanced technical solutions, it ensures long-lasting and trouble-free operation in all conditions.
