B-Line 10250TA55 30.5 mm, Heavy-Duty Pushbutton Operator

It mounts in a standard 30.5 mm panel opening, the common heavy-duty control station hole size. That means it drops straight into an existing 30.5 mm cutout on a panel door or enclosure without re-punching.

Yes. The operating mode is latched by a padlockable attachment in the down position, and the head is spring loaded. Push it in, lock it, and the machine stays disabled until someone with the key releases it, which is what makes it usable for lockout of a control circuit.

The operator carries NEMA 3, 3R, 4, 4X, 12 and 13 ratings, so it suits rain-exposed and washdown locations as well as dusty and oily industrial panels. The enclosure it goes into has to hold the same rating for the assembly to be sealed.

No, not where it sees sun. The jumbo mushroom head is plastic and is not recommended for applications with exposure to ultraviolet light. For an exposed outdoor station, pick a head that is rated for UV exposure even though the operator itself carries NEMA 3R and 4X ratings.

This is the operator only: the jumbo red mushroom head, chrome bezel and padlockable latching mechanism. Contact blocks (NO/NC) mount to the back of the 10250T operator and are ordered as separate items to match your control circuit.

If your existing stations are 30.5 mm heavy-duty units with red mushroom heads and chrome bezels, this matches visually and in hole size. What differs between models in the 10250T family is the head size and the operating mode, so confirm the others are also jumbo heads with padlockable down-position latching rather than maintained pull-to-release.

No. It is non-illuminated, so there is no lamp or LED module behind the head and no separate voltage to specify. If the panel needs a lit indication that the stop is engaged, use a separate pilot light.
