Eaton E30KA204 – Frequently Asked Questions

1) Is this E30 pushbutton a complete emergency stop station or just the operator?
This is the actuator/operator portion only. It is made for use with Eaton square multifunction pushbutton assemblies, so you still need the matching contact blocks and, if you are building a standalone station, an enclosure. Plan the contact block count around your safety circuit before you order.
2) Can this Eaton emergency stop button be used in a washdown or oily machine shop area?
Yes. It is built in the Watertight/Oiltight square multifunction configuration, which is what you want on panels seeing moisture, dust, cutting oils, or washdown. For dry indoor control cabinets it works too, it is simply more device than you need.
3) Does the Eaton E30 emergency stop button come already marked, or do I have to order a legend plate?
It comes marked. The legend reads EMERGENCY STOP in 3/16 inch high letters, so no separate legend plate is needed for the marking itself. The actuator is red, which is the conventional color for an e-stop operator.
4) How much panel space do I need to allow for this Eaton E30 emergency stop device?
Allow for a footprint of 4 inches by 5 inches (width by length/depth) in addition to the 30.5 mm cutout itself. That matters when you are laying out several operators in a row on a small enclosure door or fitting one beside existing devices.
