Eaton MCB, 3 Poles, C Curve - xEffect Series - 278865 FAZ-C4/3

Choose this MCB from Eaton to protect resistive and inductive loads with low inrush current against harmful short circuits and overload. It's a C curve breaker that instantly trips at 5 to 10 times its 4A rated current, which means it can handle substantial power surges. For convenience, the unit has twin-purpose terminals, so you can wire it from the top or bottom. A slim mounting width per pole of 17.7mm lets you achieve maximum packing efficiency on your control circuit. This MCB is a reliable choice for protecting industrial and commercial switchgear used in motors and lighting applications.

Features & Benefits

• 3-position DIN-rail clip to simplify removal from the busbar system

• IP20-rated enclosure that's protected against touch and objects larger than 12mm

• Suitable for use in a wide operating temperature range between -40°C and +75°C

• Meets IEC/EN 60898-1 safety standards for circuit breakers that provide overcurrent protection to household and similar installations

Does this MCB provide protection to people?

Yes, this MCB helps to improve safety by reducing the likelihood of current surges causing electric shocks.
