Eaton E34VFBK1 – Frequently Asked Questions
1) Will the Eaton E34 pushbutton operator fit a standard 30.5 mm panel cutout?
Yes. The E34 operator is a 30.5 mm unit, so it drops into the standard 30.5 mm hole used across most industrial control panels and stations. Overall it measures 2 in wide by 2.4 in deep by 3.4 in high, so check you have that much clearance behind the panel face before you drill.
2) Can I use an Eaton E34 30.5 mm operator in a washdown or outdoor enclosure?
Yes. The E34 corrosion-resistant operator carries NEMA 3, 3R, 4, 4X, 12 and 13 ratings, which covers washdown, wet locations and corrosive industrial atmospheres as well as dust-tight indoor panels. The rating only holds if the enclosure itself is rated to match and the operator is gasketed properly at the cutout.
3) Which Eaton E34 model do I order for a 120V illuminated pushbutton?
Two of the illuminated E34 operators are the 120V units: E34VFB120 and E34VHB120. The other illuminated versions are E34VFBK1 and E34VHBK1. If your control circuit is 120 VAC, order one of the 120 models so the lamp matches the circuit you are wiring into.
4) Do I need to order contact blocks separately for the Eaton E34?
The E34 is sold as a pushbutton operator, which is the front-of-panel actuating half of the device. The switching contacts are a separate item on Eaton's 30.5 mm platform, so specify the contact block arrangement (normally open, normally closed, or a combination) your control circuit needs when you place the order.
5) What actuator styles does the Eaton E34 30.5 mm operator come in?
Three choices. Knob, for a selector you turn and leave in position. Lever, which gives more grip when an operator is wearing gloves. And the standard round pushbutton actuator, which is what the illuminated versions use. Knob is model E34VEBK1 and lever is E34VFBL1, both non-illuminated.
6) What does the 60 degree throw on the E34 selector mean for panel layout?
The E34 operator has a 60 degree throw, meaning the knob or lever swings 60 degrees between positions. That is a short, positive sweep, so you can space these on tight centers in a control station without the handle fouling the next device, and an operator can feel the detent without looking.
7) Is the Eaton E34 pushbutton UL Listed and CE marked for a spec job?
Yes on both. The E34 30.5 mm operator is UL Listed and CE Marked, which is usually what a facility or OEM panel spec asks for on operator devices, alongside the NEMA 3 through 13 environmental ratings.
