ABB 1SBL323001R8810 (AL40‑30‑10 220 V DC Contactor)
The ABB 1SBL323001R8810 is a three‑pole DC‑operated contactor from the AL series, designed for industrial motor and power circuit control. It features three main normally‑open contacts (3 NO) and one auxiliary normally‑open contact (1 NO), with a 220 V DC coil for reliable switching in DC control applications. The low‑power DC coil enables direct driving from PLC outputs, and the contactor is suitable for use in three‑phase power circuits up to 690 V AC. Its block contactor design provides robust switching performance in motor control, lighting, and general industrial power applications.
