Circuit breaker 25kA, In=32A, characteristic B. 2-pole. AZ-2-B32 174495

Overcurrent switch – reliable protection of electrical installations

This two-pole overcurrent switch from Eaton's AZ series is a key element in protecting electrical installations from the effects of overloads and short circuits. Designed for use in both residential and industrial buildings, it provides high reliability and operational safety. A rated short-circuit breaking capacity of 25kA guarantees an effective response in emergency situations, minimizing the risk of damage and fires.

Characteristics and application

The B-characteristic switch is particularly recommended for circuits with devices generating surge currents, such as motors or transformers. The B characteristic allows for a faster response to current increase than the C characteristic, which is important for protecting against short-duration overloads. Mounting in a distribution board provides central control and protection of multiple circuits simultaneously. The device is designed to operate in AC installations with a voltage of 400V, and its width of 3 modules facilitates integration with existing systems.

Key features and benefits

• High short-circuit breaking capacity (25kA): Ensures effective protection against serious failures and limits potential losses.
• B characteristic: Ideal for protecting circuits with devices generating surge currents, providing a quick response to overloads.
• Two-pole design: Allows disconnecting two circuits simultaneously, increasing safety during maintenance or repairs.
• Mounting on TH35 rail: Standard mounting simplifies installation and replacement of the switch in the distribution board.
• Compliance with IEC 60947-2 standards: Confirms compliance with stringent safety and quality standards.
• Expandability: Compatibility with additional accessories allows you to adapt the switch's functionality to individual needs.
• Energy limitation class 3: Provides adequate protection in the event of an electric arc.
• Rated insulation voltage Ui 440V: Guarantees safe operation in various installation conditions.

The Eaton AZ-2-B32 switch is a solid and reliable solution for anyone who values the safety and durability of their electrical installation. Its versatility makes it perfect for both new installations and the modernization of existing systems.
