B-LINE E34PB2-51X – Frequently Asked Questions
1) Will the B-Line E34PB2-51X pushbutton fit a standard 30.5 mm panel hole?
Yes. The E34PB2-51X is a 30.5 mm pushbutton, which is the standard large-format control hole used on most industrial enclosures and control panels. It mounts flush to the panel face.
2) Is the E34PB2-51X a normally open or normally closed pushbutton?
Normally closed. The E34PB2-51X ships with a single 1NC contact block, so the circuit is made at rest and breaks while the button is held. If you need to energize a circuit on press, this is the wrong contact arrangement and you want an NO version instead.
3) Does the red button on the E34PB2-51X stay in when pressed, or spring back?
It springs back. This is a momentary operator, not a maintained or push-pull type, so the contact changes state only while your finger is on it. For a latching stop function you need a maintained or twist-release button, not this one.
4) Can this B-Line 30.5 mm pushbutton be used in a washdown or outdoor enclosure?
Yes. The E34PB2-51X carries NEMA 3, 3R, 4, 4X, 12 and 13 ratings, so it is suited to outdoor, raintight, hosedown and corrosion-prone locations as well as dusty and oily indoor plants. The 4X rating is the one that matters for food plants, car washes and coastal sites.
5) Is the E34PB2-51X pushbutton lit?
No, it is a non-illuminated operator. The red actuator has no lamp or LED behind it, so there is no separate supply voltage to specify when ordering. If your panel drawing calls for a lit indicator button, this unit will not satisfy it.
6) Does the E34PB2-51X come assembled with the contact block, or do I order that separately?
It ships assembled. The operator, black bezel and the 1NC contact block come together as one part number, so nothing else is required to land it in the panel and wire it.
7) Is the button on this B-Line pushbutton metal or plastic?
The actuator is plastic with a black bezel, which is part of why the unit is rated corrosion resistant for NEMA 4X service. If your spec calls for a metal actuator, this is not that variant.
8) What part number do I quote for the red 30.5 mm corrosion resistant B-Line momentary button?
Order it as Eaton B-Line E34PB2-51X, from the E34 series of 30.5 mm corrosion resistant operators. That number covers the red plastic momentary button with black bezel and one NC contact.
