The ABB A12-30-22 is a 3-pole industrial contactor designed for switching and controlling three-phase electrical power circuits in motor control and general power applications. It belongs to ABB’s A-Line series contactors, which provide reliable performance for industrial automation, motor starters, HVAC systems, pumps, lighting circuits, and other three-phase loads.

The ABB 3HNA013638-001 SMU-03 6700-200 is a high-performance PLC control module designed for advanced automation systems, offering unparalleled reliability and efficiency.

The ABB OTM63F4C10D380C is a dual power transfer switch (change‑over switch) designed for automatic or motorized switching of electrical loads between two asynchronous power sources (e.g., utility mains and backup generator) in a three‑phase electrical system. It enables reliable continuity of power by providing a mechanism to transfer the load safely between source 1 and source 2, with built‑in isolation and switching functions according to IEC electrical standards. This kind of transfer switch is commonly used in industrial, commercial, and critical power installations where uninterrupted power is essential.
