The ABB AL26‑30‑10 24 V DC Contactor (1SBL243001R8110) is a three‑pole DC‑operated power contactor designed for reliable control and switching of three‑phase electrical power circuits up to 690 V AC. 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, making it suitable for direct control by PLC outputs and DC control systems. Its compact block‑type design with screw terminals is ideal for installation in industrial and commercial control panels. It is suitable for motor control, lighting, capacitor switching, isolation, and general power loads
