Cutler-Hammer Advantage motor starters
Cutler-Hammer Advantage motor starters
(OP)
We have had numerous random equipment outages with the Cutler-Hammer Advantage 480 volt motor starters. This typ occurs with smaller drives (less than 5 HP). We have performed extensive harmonic analysis on the plant's power. Sure our plant has a little noise, but we are clearly less than the C-H spec'd 5% THD.
Has anyone experienced this with Cutler-Hammer Advantage starters? Is it the current sensor?
Thanks for any help!

I don't recall many questions/problems on this forum related to Advantage starters over the years.

Outages:
1. Not caused by PLC. Outages happen in Local Mode or Auto Mode.
2. May be related to current sensor in the starter. Many of these "smart" starters have a metering module mounted on the bucket. And these current sensors are reading too high....in other words, a clamp-on Fluke typically reads lower amps.
Just wondered if the Forum had any experience with the Freedom Series ("dumb starters") vs the Advantage Starters vs the Advantage Plus Starters.
Thank you. We are very disappointed with these Advantage Starters.

I take it these were not failures in the starter but rather unexplained opening of the contactor?
Did the overload relay indicate a trip?

Another vendor, whom I shall not name, has carried out tests only upto 300m on 24VDC control cable, for a simialar arrangement. They accept no responsibility for control cable lengths beyond this value!!
