Overcurrent circuit breaker series 10kA 3-pole FAZ-Z1/3 278919

### Three-pole circuit breaker – reliable installation protection

This FAZ-Z1/3 series circuit breaker from Eaton is a key element of every safe electrical installation. Designed to protect three-phase circuits, it effectively responds to overloads and short circuits, minimizing the risk of damage and fire. The rated switching capacity of 10kA (according to IEC 60947-2) guarantees quick and reliable disconnection in the event of a failure, protecting both devices and people.

The circuit breaker is characterized by its versatility – it can operate at AC 400V and has a “Z” tripping characteristic, which means high sensitivity to short-term current surges. This is particularly important when protecting electronic devices sensitive to overvoltage. DIN rail mounting simplifies integration with existing distribution boards, and the compact dimensions (3 modules wide) allow for optimal use of space.

**Solid construction and a wide range of applications**

The FAZ-Z1/3 circuit breaker is made of high-quality materials, which ensures its durability and reliability even in harsh working conditions (ambient temperature from -25°C to 75°C). The ability to connect wires with a cross-section from 1 to 25 mm² (solid and stranded) provides flexibility in choosing the appropriate cables. The IP20 degree of protection provides basic protection against touch and ingress of solid objects.
