EATON FAZ-B13/1 Miniature Circuit Breaker, 1-Pole, 13 A, B-Characteristic, 6 kA 278533

The FAZ-B13/1 stands out with its B-characteristic tripping, tailored for circuits where moderate inrush currents are expected, such as lighting and socket outlets. Its 13 A rating fills a niche between common 10 A and 16 A breakers, offering precise protection without oversizing.

Highlights

• 1-pole design, 1 module width (17.5 mm) for space-saving DIN rail installation
• Rated current 13 A with B-characteristic for reliable overload and short-circuit protection
• Breaking capacity of 6 kA at 230/400 V AC, compliant with IEC/EN 60898-1
• Screw terminals accept conductors up to 25 mm², ensuring secure connections
• Wide operating temperature range from -25 °C to +75 °C

In daily use

Installation is straightforward on standard 35 mm DIN rails, and the screw terminals provide a solid grip on conductors from 1 to 25 mm². The breaker's energy limiting class 3 ensures effective current limitation during faults, protecting downstream equipment. Its mechanical endurance of over 20,000 operations and electrical endurance of over 10,000 operations mean years of dependable service.
