Eaton E30KA330 – Frequently Asked Questions

1) Is the Eaton E30 green START pushbutton a complete switch, or do I need an operator and contact blocks too?
This is the actuator only. The E30 green START button is meant to be used with an Eaton square multifunction pushbutton operator, so you'll need that operator body and the contact blocks for your circuit to make a working start station. Order the actuator to match the operator type you already have in the panel.
2) What is the difference between the Type A, B, C and E extended actuators on the Eaton E30 START button?
The actuator style is the ordering choice on this green START button, and there are four: Type A extended (E30KA330), Type B extended (E30KB130), Type C extended (E30KC130), and Type E extended (E30KE130). All four are extended-style green buttons carrying the START legend; the letter identifies the actuator type that matches your E30 square multifunction operator. Pick the letter that matches the operator already installed, or the one your panel drawing calls out.
3) Will this Eaton pushbutton fit a standard 30.5 mm panel hole?
Yes. The E30 green START actuator uses the 30.5 mm square multifunction footprint, which is the standard heavy-duty industrial panel cutout size, so it drops into existing 30.5 mm E30 operator locations without redrilling the enclosure door.
4) Can this green START button be used in a washdown or oily machine shop environment?
It is built as a square multifunction Watertight/Oiltight actuator, which is what you want on machine tools, food or beverage lines, and any panel that gets hosed down or splashed with coolant and cutting oil. The sealing is at the operator, so the rating holds only when it is mounted on a matching E30 Watertight/Oiltight operator.
5) Is an extended actuator a good choice for a start button, or should I use flush?
Extended buttons stand proud of the panel so they can be hit fast and found by feel, which suits a start control on a machine an operator runs all shift. The tradeoff is that a projecting button is easier to bump accidentally, so where nuisance starting is a concern a flush or shrouded actuator is the safer pick. All four styles offered here are extended green START buttons.
6) How big is the START lettering on this Eaton E30 button?
The START legend is marked in 3/16 inch high letters on the green button face. That is large enough to read across an operator station, and it means you do not need a separate legend plate to identify the start function.
