Overcurrent circuit breaker 25kA, In=32A, characteristic D. 4-pole. AZ-4-D32 174543

Overcurrent circuit breaker – reliable protection for electrical installations

This four-pole circuit breaker from Eaton's AZ series, with a rated current of 32A 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, 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 choice for both professional installers and end users.

Characteristics and application

A circuit breaker with a D characteristic is particularly recommended for protecting circuits with receivers with high inrush current, such as motors, transformers or heating devices. The D characteristic allows for short-term exceeding of the rated current without unnecessary tripping, which prevents false alarms and downtime of devices. A width of 6 modules facilitates mounting in standard distribution boards. Energy limitation class 3 and surge category 3 confirm its high resistance to interference.

Advantages and benefits

• High short-circuit breaking capacity (25kA): ensures effective protection against serious failures and damage to the installation.
• D characteristic: ideal for protecting circuits with receivers with high inrush current – motors, pumps, heating devices.
• 4 poles: allows protection of the entire three-phase circuit with neutral conductor.
• Expandability: compatible with additional auxiliary accessories, increasing system functionality.
• Compliance with standards: meets the requirements of IEC 60947-2 standards, guaranteeing safety and reliability.
• Durable construction: made of high-quality materials ensures long device life.
• Width of 6 modules: facilitates mounting in standard electrical distribution boards.
• IP20 degree of protection: provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.

Eaton AZ series circuit breakers are a proven choice for demanding electrical installations – both in residential, commercial and industrial buildings. Thanks to the high quality of workmanship and compliance with applicable standards, they ensure safety and reliability for years to come.
