Eaton E30KB300 – Frequently Asked Questions

1) Can this Eaton green pushbutton be used in a washdown or oil-exposed machine area?
That is what it is built for. The E30 green pushbutton is a Watertight/Oiltight device, so it holds up in wet, washdown, and oil-exposed industrial locations where a general purpose operator would fail.
2) What is the difference between the Type A, B, C, D and E actuators on the Eaton E30 green pushbutton?
Actuator style is the choice you make when ordering. The green E30 is offered as Type A extended (E30KA100), Type A short (E30KA350), Type B extended (E30KB300), Type C extended (E30KC300), Type D extended (E30KD200), and Type E extended (E30KE300). Type A is the only one offered in both a short and an extended button, so if you need a low-profile actuator that sits closer to the panel face, Type A short is the one to specify.
3) Does the Eaton E30 green pushbutton come with contact blocks, or do I order those separately?
The green E30 is the operator half only, an actuator for the square multifunction pushbutton line. The contact blocks and mounting components that complete a working station are separate E30 modular parts and have to be ordered alongside it. Plan the order as actuator plus the contact arrangement your circuit needs.
4) Does the green Eaton E30 pushbutton come pre-marked START?
No, the actuator ships with a blank legend. You label it to match the function, which is useful when the green button is a start, run, or reset depending on the machine. Green is the color called out for the actuator itself, for quick identification on a crowded panel.
5) Can I mix this green E30 button with other colors in the same control station?
Yes. The green unit is one color option within Eaton's E30 square multifunction line, and because the whole family shares the 30.5 mm mount and the same modular build, green, red and other actuators sit side by side in one enclosure using the same cutout and the same contact blocks.
6) Can I use the Eaton E30 green pushbutton to replace a button in an existing control station?
It suits control station retrofits as long as the existing cutout is the 30.5 mm size and the station takes E30 square multifunction operators. Match the actuator style you are pulling out, extended or short, so the button projection at the panel face stays the same.
