B-LINE E34PB1-51X – Frequently Asked Questions
1) Will the B-Line E34PB1-51X pushbutton fit a standard 30.5 mm panel hole?
Yes. The E34 Series E34PB1-51X is a 30.5 mm pushbutton, which is the standard large-format control hole used on most industrial enclosures and machine panels. It mounts flush to the panel face.
2) Is the E34PB1-51X a normally open or normally closed pushbutton?
It ships with a single normally closed contact block (1NC). Press it and the circuit opens; release and it closes again, because the operating mode is momentary. If your control scheme needs a normally open contact to energize a coil on press, this is the wrong contact configuration for that leg.
3) Can this pushbutton be used in a washdown or outdoor enclosure?
The E34PB1-51X is rated NEMA 3, 3R, 4, 4X, 12 and 13. The 4 and 4X ratings cover hosedown and washdown areas, 4X adds corrosion resistance for food processing, chemical and coastal installs, and 3/3R cover outdoor rain and sleet exposure. 12 and 13 handle dust, drips and oil in general plant areas.
4) Can I use this as an emergency stop button?
No. An E-stop has to be a maintained, trapped-key or twist-to-release mushroom head under most machine safety specs, and the E34PB1-51X is a momentary black flush button that springs back the moment you let go. Use it for stop, reset, jog or general control, and specify a dedicated red mushroom E-stop operator for the safety circuit.
5) Does the B-Line E34 pushbutton light up?
No. The E34PB1-51X is a non-illuminated button, so there is no lamp or LED and no separate supply voltage to run to it. If you need an indicating button that shows circuit state, you need an illuminated operator instead.
6) Is the button head metal or plastic, and what color is it?
The actuator is black plastic. Plastic holds up well against the chemicals and salt spray you get in 4X areas, but if your spec calls for a metal operator on that panel, this is not it. Black is the usual choice for stop, reset or general control functions rather than a start button.
7) Is the E34PB1-51X sold as a complete assembled unit or do I order the contact block separately?
It comes assembled. The operator, the 30.5 mm flush mount hardware and the 1NC contact block are supplied as one unit, so there is no separate contact block or latch to order to get the button working. Add contact blocks only if your circuit needs poles beyond the single NC.
8) What part number do I quote to match the other E34 buttons on my panels?
Order by B-Line manufacturer part number E34PB1-51X, in the E34 Series. That gets the 30.5 mm corrosion resistant, non-illuminated momentary pushbutton with a black plastic actuator and 1NC contact, so it will match existing E34 openings on the same panel.
