M300 P

Discover a new level of performance, efficiency and safety with the M300 P miniature circuit breaker. Fully compatible with ABB's existing System pro M compact® accessories, the M300 P provides reliable short-circuit protection in demanding applications such as industrial, commercial buildings, data centers and e-mobility, reducing downtime and increasing service continuity. In addition, the new generation M300 P offers new features such as the Trip Position Indicator (TPI), the dual DIN rail clip and a QR code for quick access to documentation, certificates and technical data. The new M300 P supports short-circuit protection only. A thermal overload protection element can be added separately.
