Wondering if any of my esteemed colleagues here have run into the subject line company? They are selling something called PhaseBack, which acts as a surge suppressor and also claim to reduce arc flash (they claim an 85% reduction in arc flash potential).

Appreciate the feedback in advance...it frankly reminds of the snake oil salesman years ago w/ power factor correction products (our utility doesn't have PF penalties...so it didn't make sense for us, and our PF wasn't that low besides).

PS I can post more info if needed...I know about posting links to vendor websites.

Never heard of it. Looked it up. Extremely skeptical.

- Harmonic filter
- Voltage imbalance corrector
- Surge suppressor /lightning arrestor
- Arc flash energy eliminator
- Ground fault preventer
- Works from 5 VDC up to 230,000 VAC

One of our clients requires these devices at all of their facilities. It looks like 3 small transformers and a resistor in a box. I don't understand how it's supposed to work. It does not seem to have an NRTL listing.
