Overcurrent circuit breaker 25kA, In=40A, characteristic D. 2-pole. AZ-2-D40 174505

Reliable protection of electrical installations with EATON AZ-2-D40 circuit breaker.

This two-pole circuit breaker from EATON's AZ series, with a rated current of 40A and D characteristic, is a key element ensuring safety in every electrical installation. Designed to protect against overloads and short circuits, it offers high reliability and performance. A rated short-circuit breaking capacity of 25kA guarantees an effective response in emergency situations, minimizing the risk of damage and downtime.

The AZ-2-D40 circuit breaker is distinguished by its versatile application – it will work both in home and industrial installations. The D characteristic provides a delayed tripping, which is particularly important when protecting circuits with receivers with high inrush current, such as electric motors or transformers. This avoids unnecessary tripping of the circuit breaker when starting devices.

Features and benefits:

• High short-circuit breaking capacity (25kA): Ensures a quick and effective response in the event of a short circuit, protecting the installation from serious damage.
• D characteristic: Ideal for protecting circuits with receivers with high inrush current – motors, transformers, welding machines. Allows for smooth start-up of devices without the risk of unnecessary circuit disconnection.
• Two-pole design: Allows disconnecting two phases simultaneously, which increases safety and facilitates servicing of the installation.
• Compliance with IEC 60947-2 standards: Guarantee of safety and reliability confirmed by certificates and tests.
• Protection degree IP20: Protection against touching with a finger and solid objects larger than 12.5 mm – safe operation in standard conditions.
• Width of 3 modules: Compact dimensions allow for easy mounting in electrical switchboards with limited space.
• Expandability: Compatible with a wide range of auxiliary accessories (e.g. status indicators, busbars), allowing you to adapt the functionality to individual needs.

Applications:

The EATON AZ-2-D40 circuit breaker is used in:

• Electrical installations in residential and public buildings
• Main and sub-distribution boards
• Circuits powering electric motors, transformers and other devices with high inrush current
• Surge protection systems (in combination with appropriate accessories)
• Applications requiring high reliability and safety – also in railway transport (railway approvals).

EATON AZ series circuit breakers are a proven choice for professionals and users who value quality, safety and durability of electrical installation solutions. They provide comprehensive protection of the electrical installation against the effects of overloads and short circuits, guaranteeing peace of mind for users and minimizing the risk of costly failures.
