Square D 9066RA1 – Frequently Asked Questions

1) What does the Square D 9066RA1 reset kit actually do on a motor starter?
It puts the overload reset on the outside of the enclosure. A grey push button marked RESET mounts into the cover of a NEMA 1 or NEMA 12 enclosure, and a threaded reset rod links that button to the Type S overload relay inside. After a thermal trip, an operator presses the button and restores the starter without opening the panel or exposing live parts.
2) Will the 9066RA1 work with my overload relay, or is it Type S only?
Type S only. The 9066RA1 external reset mechanism is built for the Square D Type S overload relay platform, and the rod is made to actuate that relay's reset mechanism. If the starter in your panel uses a different Square D overload class, this kit is not the part for it. The kit is also listed as compatible with accessory 9066W1.
3) Do I need this kit if I'm buying a new Square D starter?
Usually not. The external reset mechanism comes standard installed on non-reversing, reversing, combination, and multispeed starters. Buy the 9066RA1 as a field replacement when the original button or rod is broken or missing, or when you are building a panel from loose components and need external reset access.
4) Can this be installed on a starter that is mounted away from the enclosure door?
Yes. Both direct mount and separate mount configurations are supported, so the relay does not have to sit directly behind the cover opening. The button itself mounts to the enclosure door either way.
5) What part number do I order for a Square D external reset button?
Order Square D 9066RA1, the Type S external reset mechanism kit for NEMA 1/12 enclosures. That single MPN covers the button operator and the threaded rod together.
6) Does this reset kit restrict which thermal units I can run in the overload relay?
No. The Type S platform this kit serves uses field interchangeable thermal units, so you can swap the heater element to match a replacement motor's full load amps and keep the same external reset hardware in the door.
7) Is the Square D 9066RA1 RoHS compliant and where is it made?
It is in scope for and compliant with RoHS EU, and it is manufactured in Mexico. Specification-driven jobs with material declarations on the submittal usually want both of those on record.
