Overcurrent circuit breaker 25kA, In=25A, characteristic B. 3-pole. AZ-3-B25 174507

Three-pole overcurrent circuit breaker – reliable installation protection

This three-pole overcurrent circuit breaker from Eaton's AZ series is a key element of electrical protection in every circuit. Designed to protect against overloads and short circuits, it ensures safe use and long-term reliability. A rated current of 25A combined with characteristic B makes it ideal for protecting circuits with moderate inrush current, such as lighting, sockets or household appliances. The short-circuit breaking capacity of 25kA guarantees an effective response in emergency situations, minimizing the risk of damage and fires.

Design and application

The AZ-3-B25 circuit breaker is made of high-quality materials, which translates into its durability and resistance to environmental conditions. Compact dimensions (4.5 modules wide) make it easy to install in electrical distribution boards. Energy limitation class 3 and surge category III confirm its ability to operate in demanding network conditions. IP20 protection degree provides basic protection against contact and ingress of solid objects.

This model finds wide application both in domestic and industrial installations. It is particularly recommended for protecting circuits with loads with a load characteristic close to resistive, where short-term current surges are not a problem. Additionally, the ability to mount accessories expands the functionality of the circuit breaker, allowing it to be adapted to individual installation needs.
