Why choose it

The FAZ-B16/3 offers a compact 3-module design that saves space in distribution boards. Its high short-circuit breaking capacity of 10 kA ensures reliable protection in demanding installations. The screw terminals accommodate a wide range of conductor sizes, simplifying wiring.

Ideal use cases

• Protection of three-phase circuits in residential and commercial buildings
• Distribution boards and sub-distribution boards
• Protection of motors, transformers, and other inductive loads (with Type B characteristic)

Good to know

The Type B tripping characteristic means the breaker trips instantaneously at 3 to 5 times the rated current, providing fast response to short circuits while avoiding nuisance tripping from inrush currents. It is compliant with IEC/EN 60898-1.
