B-Line 30.5 mm, Heavy-Duty Assembled Control Station

It's a factory-assembled three-element station: two momentary pushbuttons legended START/STOP plus one indicating light. The buttons are flush type, the light is a neon indicator in amber. Momentary operation means the contacts change state only while the button is held, which is what a standard motor start/stop circuit with a holding contact expects.

The 10250ED853 station carries NEMA 3, 3R, 3S, 4, 12 and 13 ratings, so it handles rain, sleet, windblown dust, hosedown and oil or coolant environments as well as ordinary indoor plant use. The enclosure itself is listed as NEMA 1 die cast construction, so treat the higher ratings as the enclosure's environmental performance and mount it with the gasketing and conduit entries kept intact.

Surface mount. The 10250ED853 is a self-contained die cast box that fastens to a wall, machine frame or column, so no panel cutout is needed. It measures 8.1 by 4.9 by 4 inches and weighs 1.4 lb, light enough for two fasteners into a machine frame.

Yes, it's built on the 30.5 mm heavy-duty platform of the 10250ED series, so the standard 30.5 mm mounting hole size used across that line applies. If you already stock 30.5 mm heavy-duty buttons and pilot lights for other stations, they are the same hole size. 30.5 mm is the traditional heavy-duty industrial size, distinct from 22 mm compact operators, which will not drop into the same opening without an adapter.

For a straight START/STOP with a run indicator, the assembled route saves the build. The 10250ED853 arrives as a complete three-element station, legended, with the amber neon light already fitted, so the only field work is mounting and wiring to your starter's coil and holding circuit. Build it up from an empty enclosure and separate operators only when you need a combination the assembled catalog doesn't cover, such as a selector switch, mushroom E-stop, or a non-standard legend.

It's a neon indicating light with standard illumination, in an amber lens. Neon means it runs on line voltage directly rather than through a step-down transformer like an incandescent or LED full-voltage unit, so match your control circuit voltage to the neon light's rating before wiring it in.

Both buttons are flush type. Flush buttons sit level with the guard ring, which reduces accidental operation if the station is mounted where an operator brushes past it. If you need a palm-operated stop, a flush START/STOP station is the wrong choice, and you should specify a station with an extended or mushroom head stop instead.

Order by manufacturer part number 10250ED853, from the B-Line 10250ED heavy-duty 30.5 mm assembled station series. That number covers the two-pushbutton START/STOP with amber neon indicating light in the die cast surface-mount enclosure.
