Overcurrent circuit breaker 25kA 3-pole. Characteristic B, series AZ-3-B80 174512

Three-pole overcurrent switch – reliable installation protection

This three-pole overcurrent switch with B characteristic is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and people. The rated current of 80A makes it ideal for securing circuits with higher power consumption, and the high short-circuit breaking capacity (25kA) guarantees a quick response in emergency situations.

Design and parameters for professionals

The AZ-3-B80 series switch is designed for easy mounting on a TH35 rail. Its width of 4.5 modules allows for optimal use of space in the distribution board. Energy limitation class 3 and surge category III confirm its high resistance to interference and ensure stable operation even in difficult conditions. Protection degree IP20 protects against accidental contact, increasing safety. Rated voltage 400V and rated impulse withstand voltage 4kV guarantee compatibility with most electrical installations.

Universal application and benefits

This switch is used in both domestic and industrial installations. Thanks to the B characteristic, it provides protection for devices sensitive to short-term current surges, such as motors or transformers. The possibility of additional equipment allows the switch to be adapted to the specific needs of a given installation. Solid construction and high quality workmanship translate into long life and trouble-free operation, which minimizes the risk of downtime and costly repairs. The rated short-circuit breaking capacity Icu is 20kA at 230V and 20kA at 400V – this is an important parameter for ensuring safety in the event of a short circuit.
