Siemens Furnas 75D70131J 24 Volt Contactor Coil

Siemens Furnas 75D70131J is a genuine replacement coil for 75D‑frame Furnas/Siemens contactors, delivering 24 VAC operation at 60 Hz in a Size 4 package. The coil code J denotes a 24‑volt AC coil, specified for energizing the contactor’s magnetic core to switch heavy loads in motor‑control and process‑control circuits. Sold as a coil kit (not a complete starter), it is designed to drop into 75D‑series contactors and is frequently cataloged for elevator‑contactor use where 24 VAC control is standard. As a 75D frame coil, it is compatible with a broad range of 75D starters and provides the impedance and magnetic sensitivity Siemens recommends for reliable operation. Part number 75D70131J identifies this specific 24 VAC coil assembly, enabling straightforward field replacement without altering the existing contactor assembly. Typical applications include industrial machinery, conveyors, pumps, and other equipment that rely on 24 VAC control of heavy‑duty contactors; always verify compatibility with your 75D Size 4 unit and ensure the coil’s voltage and frequency match your control circuitry.
