The ABB AL9‑30‑10 24 V DC Contactor (1SBL143001R8110) is a compact three‑pole DC‑operated power contactor designed for control and switching of three‑phase motors and general power circuits. It features three main normally‑open (NO) contacts and one built‑in auxiliary normally‑open contact for control signalling or interlock functions. The contactor uses a 24 V DC control coil with low power consumption, enabling direct operation from DC control systems or PLC outputs. It is suitable for industrial and commercial usage across a wide range of applications where reliable contact switching is required.
