What It Is & Where It Fits
The B7-30-10-01: This is a miniature contactor — a magnetically operated switch used to control motor loads and other power circuits in control panels. The 24V coil allows direct interface with PLC outputs or control relays without an intermediate transformer. As a motor starter component, it typically mounts on DIN rail inside an enclosure, switching three-phase or single-phase loads up to its rated capacity. The miniature form factor saves panel space compared to full-frame contactors.
Sourcing Decision
If your BOM calls for the B7-30-10-01, the eol_hot status means you cannot order it new from the manufacturer. For new designs, consider evaluating a current-production miniature contactor with a 24V coil from the same voltage class.
