B-Line 10250T76B Assembled, 30.5 mm Pushbutton

Yes. The 10250T76B carries NEMA 3, 3R, 4, 4X, 12 and 13 ratings, which covers rain and sleet outdoors, hosedown and corrosion-resistant 4X duty, and dust or oil in industrial panels. That makes it workable for food plants, car washes and exterior control stations as long as the enclosure itself carries the same rating.

It ships assembled with a 1NO-1NC contact block. That gives you one normally open contact to make the command circuit and one normally closed contact you can drop into an interlock, a stop string, or a status input. If your logic needs two NO contacts, this factory-assembled unit is not the one to buy.

Momentary. The contacts change state only while the button is held and spring back the instant you let go, so it suits jog, start, reset and test functions. For a function that has to stay latched, such as a two-position selector or a maintained stop, you want a maintained operator instead.

The actuator is a blue extended plastic button in a chrome bezel. Blue is commonly used for a mandatory action such as reset or a specific assigned function rather than start (green) or stop (red). The extended profile stands proud of the bezel, so it is easier to hit with a gloved hand than a flush button, but it is also easier to bump, which matters if it sits where operators brush past it.

It is part of the same 10250T heavy-duty 30.5 mm family, so it shares the mounting and standardizes with the other operators on the same panel. For MRO stock, ordering it assembled means the actuator, lamp unit and 1NO-1NC block arrive as one part number rather than as separate pieces you have to build up.

The actuator itself is plastic, set in a chrome bezel. Plastic keeps the operating surface non-conductive and holds the blue color through the part rather than as a coating. If your spec calls for an all-metal actuator, this is not the right catalog number.
