Eaton M22-ES-MS1 – Frequently Asked Questions

1) Will the Eaton M22-ES-MS1 key work on any M22 pushbutton, or only certain operators?
The M22-ES-MS1 is a spare key for Eaton M22 key-release pushbutton operators only. It is cut to the MS1 key code, so it works with M22 key-release operators built to that same code and nothing else. It is not a general-purpose key and it does not operate standard mushroom, flush, or selector-switch operators in the M22 line.
2) I need more keys for our M22 key-release stations. What do I tell purchasing to order?
Specify Eaton M22-ES-MS1, the MS1-coded extra key for the M22 modular pushbutton line. The key code is what matters on the order: a key cut to a different code will not turn an MS1 operator, so match the code stamped on the operator you are keying to.
3) My M22 key-release operator came with a key already. Do I need to order this one too?
One key ships with each M22 key-release operator. The M22-ES-MS1 is the extra, so order it when you want a second key for a shift lead, a spare in the maintenance crib, or a replacement for one that has gone missing. Facilities running a spares program for M22 stations typically keep a few on the shelf.
4) Is this M22 key rated for a washdown or outdoor control panel?
The M22-ES-MS1 key is rated IP66, NEMA 4X, and NEMA 13, the same environmental standards as the M22 operators it serves. That covers hose-down washdown areas, outdoor enclosures, and oily or dusty industrial locations. Keep in mind the enclosure rating on the finished station depends on the operator and gasket being installed correctly, not on the key.
5) Does the Eaton M22 series use a 22.5 mm panel cutout?
The M22 platform is a 22.5 mm modular system, which is what the M22-ES-MS1 key is matched to. If your panel is drilled for 22.5 mm operators, you are in the right family. The key itself does not mount to the panel; it is the loose key for the key-release operator installed in that hole.
6) Is the Eaton MS1 key approved for use on equipment shipping to Europe or China?
The M22-ES-MS1 carries CE marking and CCC marking, so it fits machine builds destined for the European and Chinese markets without a separate accessory approval.
