Y Voltage configuration is quite common

Think "stationary windings" and "rotating windings". Motor technology can get way more involved.

I agree, I think Low-Peak fuses are just the name assigned to this style, it's not actually a fuse type.

Watt loss is imminent for every device due to the sum of all components combined.

The basic frequency drive diagram reminds me of an electrical one-line diagram.

Great job with the code lists for the 160 drive! These posts are helpful for quick alarm reference.

Where are Power Tech drives made? This is where I would start this conversation. Country of manufacture matters when I buy any drive for any application. Power Tech isn't a very popular brand.

I actually had some recent experience with Cutler hammer contactors. I purchased an aftermarket Cutler Hammer contact kit that is coated with a silver alloy. I double checked the size and the load on the contactor and everything checks out within spec. All I can do is wait it out and see how it holds up. They were made in Mexico. It would be hard to tell at this point if these contacts are any good.

Again, nice job with these code lists for the 140 drive!
