B-LINE 10250T77G – Frequently Asked Questions
1) What panel hole size does the B-Line 10250T77G pushbutton need?
It mounts in a standard 30.5 mm panel opening, which is the common heavy-duty control station hole size (also called 1-3/16 inch). The unit ships assembled, so the operator, contact block and light unit come together as one part number, 10250T77G.
2) Is the 10250T77G a normally open or normally closed pushbutton?
Normally closed. The 10250T77G carries a single 1NC contact and operates momentary, so the circuit is held closed at rest and breaks only while the button is pressed. If you need a start function that makes a circuit on press, this is the wrong contact arrangement, you want an NO version.
3) Does the green illuminated pushbutton need a separate transformer or resistor for 120V control?
No extra parts. The light unit is an incandescent, transformer type rated 120 Vac, so it wires directly to a 120 volt control circuit. The lamp inside is a #755.
4) Can this pushbutton be mounted in a washdown or outdoor enclosure?
Yes. The 10250T77G is rated NEMA 3, 3R, 4, 4X, 12 and 13, which covers outdoor rain exposure, hosedown, corrosion resistant duty and oil or dust in industrial plants. Enclosure integrity still depends on the box it goes into and the gasket being seated correctly.
5) Is the actuator flush or does it stick out past the bezel?
Extended. The green plastic actuator projects out from the chrome bezel, which makes it easier to hit with a gloved hand but leaves it more exposed to accidental operation than a flush button. For a stop function where bumping matters, use a guarded or mushroom style instead.
6) Is green with a 1NC contact the right choice for a stop button?
Electrically a 1NC momentary contact is the standard stop arrangement, but green is conventionally a run or start color and red is used for stop. The 10250T77G is green and illuminated, so it reads as a run indicator or an interlock button rather than a stop. If the station needs a red stop, order a red actuator version.
7) Will the 10250T77G fit an existing 10250T series control station?
Yes, it is part of the 10250T heavy-duty 30.5 mm line, so it drops into the same panel opening as other 10250T operators and keeps one spare parts standard across your stations. The chrome bezel and green extended actuator will match other 10250T chrome bezel units on the same panel.
8) Does the button stay lit all the time or only when pressed?
The lamp circuit and the contact are separate. The 10250T77G is an illuminated unit with a 120 Vac light unit, and the 1NC contact is momentary, so how the lamp behaves depends on what you feed the light unit from. Wire the lamp to the circuit you want indicated, not to the button's own contact, if you want steady indication.
