Eaton FAZ-K16/3 16 A 3-Pole K-Characteristic Miniature Circuit Breaker 278911

The Eaton FAZ-K16/3 stands out for its K tripping characteristic, which is tailored for protecting circuits with high inrush currents such as motors, transformers, and control transformers. Unlike standard B or C curve breakers, the K curve allows for reliable operation without nuisance tripping on inductive loads while still providing effective short-circuit protection.

Highlights

• Rated current: 16 A, 3-pole configuration
• K tripping characteristic for high inrush current applications
• Rated breaking capacity: 10 kA according to IEC/EN 60898-1
• DIN rail mounting with screw terminals, 1–25 mm² capacity
• Front protection IP40, terminals IP20

In daily use

Installation is straightforward on standard 35 mm DIN rails. The screw terminals accept solid or stranded conductors from 1 to 25 mm², ensuring secure connections in distribution boards. The breaker's compact design fits standard modular enclosures, and its mechanical endurance of over 20,000 operations guarantees long service life even in demanding industrial environments.
