Posted 7 Jan 2019 Gents! I need to replace a Cutler-Hammer Panelmate model 1550 Part number 92-01667-00. I found a few identical-looking units on Ebay. They do not have the identical part numbers. Examples 92-01797-08 92-01262-01 92-01262-07 92-10755-06 Will any of these units replace the one I have? They all say they are Panelmates, and one has 1550THX. They all look right. What is the significance of the different part numbers? Date-codes? Share this post Link to post Share on other sites
