The ABB BC7‑30‑10‑2.4 is a compact 3‑pole mini‑contactor from ABB’s BC7 family, designed for switching small to medium 3-phase or single-phase AC loads, as well as general-purpose resistive or motor loads. The “2.4” suffix indicates a low-power DC coil variant (17–32 V DC, 2.4 W), which enables control from low-voltage DC control circuits, such as PLC outputs or control logic systems. The contactor provides three main normally‑open contacts (3 NO) for the main circuit and one auxiliary normally‑open contact (1 NO) for control or signaling use. Its compact size, modest power ratings, and low coil power consumption make it suitable for control panels, building automation, small motor starters, HVAC, lighting, and other light-to-medium duty switching applications.
