The ABB AF370B-30-22RT-12 is a contactor with a control coil rated for 48-130V AC/DC, meaning it pulls in and holds across that entire voltage range without needing a separate coil for 48V and 110V systems — one part covers both common control voltages in industrial panels.
Deployment context
Mounts on DIN rail in a standard control panel enclosure. The 48-130V coil range makes it a drop-in for panels with mixed control voltages — no rewiring for a coil changeout when the control transformer taps are set for 110V but the site runs 48V pilot devices.
