EATON FAZ-C16/3 16 A 3-Pole C-Curve Miniature Circuit Breaker

The EATON FAZ-C16/3 stands apart from conventional miniature circuit breakers by combining a compact 3-pole design with a precise C-curve trip characteristic, making it a dependable choice for protecting motor and transformer circuits against overloads and short circuits. Its 10 kA breaking capacity and energy limiting class 3 ensure robust performance in demanding industrial and commercial installations.

Highlights

• 16 A rated current with C tripping characteristic (5–10 × In) for inductive loads
• 3-pole configuration for three-phase circuits up to 400 V AC
• High 10 kA rated breaking capacity (Icn) per IEC/EN 60898-1
• DIN rail mounting with IP20 terminal protection
• Wide operating temperature range from -25 °C to +75 °C
• Long electrical and mechanical life: >10,000 and >20,000 operations

In daily use

Installed on a standard DIN rail, the FAZ-C16/3 provides reliable protection for motors, pumps, and control circuits. Its C-curve allows for inrush currents without nuisance tripping, while the 10 kA breaking capacity handles high fault currents safely. The screw terminals accept solid or stranded conductors from 1 to 25 mm², and the clear ON/OFF indicator simplifies status checks. With IP20 protection at the terminals, it is suitable for distribution boards and control panels where accidental contact is prevented.
