Eaton xEffect Miniature Circuit Breaker 2-Pole 50A Type B 415V AC 10 kA Breaking Capacity 278739 FAZ-B50/2

Eaton 278739 FAZ-B50/2 Miniature Circuit Breaker is a high-quality, reliable 2-Pole device rated for 50A current with Type B tripping characteristics and a rated AC voltage of 415V. It is part of the xEffect series designed for DIN Rail mounting primarily in industrial, commercial, and residential control panel applications.

This circuit breaker features a thermal magnetic tripping mechanism that provides six levels of over-current protection, ensuring safety for wiring and connected equipment. The current limiting design interrupts short circuits quickly, minimizing damage by reducing let-through energy. Its toggle switch is trip-free, meaning the breaker cannot be overridden by manually holding the handle on, and it can be locked in the ON or OFF position for maintenance or safety compliance.

The device is constructed for ease of installation with a twin-purpose terminal and compact panel footprint measuring 85mm wide and 73mm deep. The enclosure carries an IP20 rating to safeguard against solid debris ingress. The 10 kA breaking capacity ensures robust performance under fault conditions common in industrial and commercial power distribution.

The breaker also includes visual indicators - red or green lights - to show contact position for quick operational status checks. It is suitable for supplementary protection use in various electrical installations such as HVAC systems, manufacturing plants, and water treatment facilities, where reliable circuit interruption is necessary.
