Electricians and panel builders install the Eaton FAZ-B4/1-HS to protect 230/400 V AC circuits against overload and short circuit. This 1-pole miniature circuit breaker trips on the B characteristic, making it suitable for lighting and socket circuits with moderate inrush currents.

Key specifications

  • Rated current: 4 A
  • Tripping characteristic: Type B
  • Number of poles: 1
  • Rated short-circuit breaking capacity: 10 kA
  • Rated voltage: 230/400 V AC
  • Frequency: 50/60 Hz
  • Mounting: DIN rail
  • Module width: 1 module (17.5 mm)
  • Terminal capacity: 1 - 25 mm²
  • Degree of protection: IP20 (terminals), IP40 (front)
  • Operating temperature: -25 to +75 °C

Why choose it

The FAZ-B4/1-HS combines a compact 1-module design with screw terminals that accept solid or stranded conductors up to 25 mm². Its B curve responds quickly to short circuits while avoiding nuisance tripping on normal load peaks.

Ideal use cases

  • Protection of lighting and socket circuits in residential and commercial distribution boards
  • Control circuits in industrial panels requiring 4 A protection
  • Retrofit projects where a DIN rail mount and 1-module width are needed

Good to know

The breaker meets EN 60898 and IEC 60898. It operates reliably from -25 °C to +75 °C.
