Circuit breaker 25kA, In=80A, characteristic D. 4-pole. AZ-4-D80 174547

Overcurrent circuit breaker – reliable protection for electrical installations

This four-pole circuit breaker from Eaton's AZ series, with a rated current of 80A and D characteristic, is a key element ensuring safety in electrical installations. The short-circuit breaking capacity of 25kA guarantees effective protection against the effects of overloads and short circuits. The breaker's design is intended for durability and reliability, translating into a long service life and minimal risk of failure.

Features and application

The AZ-4-D80 breaker is designed to protect three-phase circuits in residential, commercial, and industrial buildings. The D characteristic makes it particularly recommended for protecting circuits powering devices with high inrush currents, such as electric motors or transformers. Mounting is on a TH35 rail, and the compact dimensions (6 modules wide) allow for efficient use of space in the distribution board. The IP20 degree of protection provides protection against accidental contact.

Advantages and benefits

• High short-circuit breaking capacity (25kA): ensures effective protection of the installation against damage caused by a short circuit.
• D characteristic: ideal for protecting circuits with devices with high inrush current – motors, transformers. Allows for short-term overloads without unnecessary tripping of the circuit.
• 4 poles: enable comprehensive protection of three-phase electrical circuits.
• Mounting on TH35 rail: facilitates and speeds up installation in standard distribution boards.
• 6 modules wide: allows for optimal use of space in the switchgear cabinet.
• Complies with IEC 60947-2 standards: guarantees safety and reliability of operation.
• Expandability: compatible with a wide range of Eaton auxiliary accessories, allowing you to customize functionality to individual installation needs.
• Energy limitation class 3: provides adequate protection in the event of an electric arc.
• Rated voltage 400V and rated impulse withstand voltage 4kV: enables use in a wide range of electrical installations.

The Eaton AZ-4-D80 breaker is characterized by a rated current of 80A, a D characteristic and a short-circuit breaking capacity of up to 25kA at 400V (and 20kA at 230V).
