What does the M mean on the end of my A200 starter number?

The suffix M that appears on the end of some of the older A200 starter numbers used to indicate that it had an ambient compensated overload relay on it.  Today ALL starters come standard wtih ambient compensated overload relays so there is no longer a need to put that M on the end of the part#.  For instance, if you were looking for a A200M1CACM, you should order the A200M1CAC and you will get the exact same motor starter.  Just drop the M off.
