Eaton E30KF40 – Frequently Asked Questions

1) Will an Eaton E30K lens fit a standard 30.5 mm round pushbutton operator?
No. The E30K lens is made for Eaton's 30.5 mm Square Multifunction Watertight/Oiltight pushbutton operators, not round-actuator units. If the operator face on your panel is round, this lens will not seat correctly and you need the lens matched to that round operator instead.
2) Can I replace a cracked pushbutton lens without swapping the whole Eaton E30 operator?
That is exactly what these are for. The E30K actuator lens is sold as a replacement or upgrade component for square multifunction pushbutton operators, so a maintenance tech can change a broken or discolored lens on a machine station and leave the operator, contact blocks and panel cutout alone. Match the actuator style letter and the color when you order.
3) How do I make sure I order the right Eaton E30 lens for my existing pushbutton?
Order by the actuator style letter first, then the color. The part numbers carry both: E30KG30 is a Type G in amber, E30KJ20 is a Type J in blue, E30KK43 is a Type K in green. Pull the number off the operator or the old lens, since a Type F lens will not seat on a Type K actuator.
4) What actuator styles and lens colors do the Eaton E30 square multifunction lenses come in?
Four actuator styles, F, G, J and K, in amber, blue and green. The pairings run: Type F in amber (E30KF30) and blue (E30KF40); Type G in green (E30KG23), amber (E30KG30) and blue (E30KG50); Type J in blue (E30KJ20), green (E30KJ22) and amber (E30KJ30); Type K in blue (E30KK10) and green (E30KK43). Several additional green variants are catalogued by their own designation, E30KG21, E30KK12, E30KK13 and E30KK23.
5) Does changing the lens on a watertight/oiltight Eaton pushbutton affect the seal?
No, provided you use the lens made for that operator. The E30K lenses are built for operators rated Watertight/Oiltight so the assembly keeps that rating after a lens change, which is why panel builders use them on washdown-adjacent equipment rather than improvising a cover.
6) Can I get a blank lens to print my own legend for an operator station?
Yes. The square multifunction E30 lens is offered with a blank legend, giving an actuator face ready for custom labeling, and it is also available in standard color-coded versions when you are following a color scheme instead of text.
7) I need to standardize stop and start colors across a plant's control panels. Which E30 lens colors are available?
Amber, blue and green are the colors offered in the square multifunction E30K lens range. If your standard calls for red on stops, that color is not part of this group, so plan the red positions around a different lens in Eaton's E30 line.
8) Is the Eaton E30K lens an electrical part or just a cover?
It is the actuator lens, the pressed face of the pushbutton, not a switch. There are no contacts, no lamp and no wiring in it. If you need the illumination element or the contact block behind the operator, those are separate items in the E30 platform.
