Overcurrent circuit breaker 25kA, In=25A, characteristic D. 3-pole. AZ-3-D25 174516

Three-pole overcurrent circuit breaker – reliable installation protection

This three-pole overcurrent circuit breaker with D characteristic is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and people. Its withstand short-circuit current capacity of up to 25kA guarantees reliable operation even in difficult conditions. The D characteristic makes it ideal for circuits with high inrush current, e.g., with devices equipped with motors.

Solid construction and wide application

The circuit breaker has been designed with durability and functionality in mind. A width of 4.5 modules makes it easy to install in standard distribution boards. The IP20 degree of protection provides basic protection against touch and ingress of solid objects. Energy limitation class 3 and surge category 3 confirm its ability to cope with disturbances in the electrical network. The rated impulse withstand voltage of 4kV further increases safety.

Key features for professionals and users
