Overcurrent circuit breaker series 15kA 3-pole FAZ-B25/3 278849

Electrical installation protection with FAZ-B25/3 circuit breaker

This three-pole circuit breaker from the FAZ series is a reliable protection for your electrical installation. Designed to protect against overloads and short circuits, it ensures safe use and long-term system stability. The rated current of 25A makes it ideal for securing circuits with medium loads, and its compact dimensions (3 modules wide) facilitate installation in distribution boards.

Characteristics and application

The FAZ-B25/3 circuit breaker is characterized by a tripping characteristic of type B, which means it reacts quickly to short-term current surges but allows for momentary overloads without unnecessary tripping. This is particularly important when connecting devices with electric motors or other elements generating high starting current. The breaking capacity of up to 15 kA at 400 V (according to IEC 60947-2) guarantees effective disconnection of the circuit in the event of a failure, minimizing the risk of damage and fire. Made of high-quality materials, the circuit breaker is durable and resistant to environmental conditions in the temperature range from -25°C to 75°C.
