Eaton FAZ-C4/1-NA Miniature Circuit Breaker (MCB), 1-Pole, C-Curve, 4 A, 6 kA, DIN Rail 102082

The Eaton FAZ-C4/1-NA is a 1-pole miniature circuit breaker (MCB) with C tripping characteristic, rated at 4 A and 6 kA breaking capacity. It protects cables and equipment against overload and short circuit in residential, commercial, and industrial installations.

Advantages

The C-curve provides reliable protection for circuits with moderate inrush currents, such as lighting and socket outlets. The compact 17.5 mm width saves space on the DIN rail, and the screw terminals accept solid conductors up to 25 mm² and flexible up to 16 mm², ensuring secure connections. The red/green contact position indicator clearly shows the switching state.

Suitable for

• Distribution boards in residential and commercial buildings
• Protection of lighting circuits and general-purpose socket outlets
• Control circuits with moderate inrush currents
• Industrial control panels requiring DIN rail mounting
