Description
Built for industrial motor control, the Eaton FA2G40-3 delivers reliable supplementary protection for 40A circuits. This three-pole device safeguards control panels where branch protection is already provided. It mounts onto standard DIN rail and serves as a replacement for legacy Klockner Moeller units. It can be substituted with FAZ-K40/3 or FAZ-C40/3 models. Rated 10 kAIC at 480Y/277VAC, it features a G-curve trip optimized for inductive loads, finger-safe terminals, and a trip indicator.Specifications

Ordered on a Saturday evening, paid for two day shipping and it arrived on time and in perfect condition. Would 100 percent be using this company going forward, beat out pricing and shipping times for all my local supply houses. Plus the staff were great to deal with.
- AHAnn H.Verified BuyerReviewingSquare D FA36100 - 100A 3 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars8/22/26Professional Service
So far, so good! The circuit breaker was installed along with a new compressor for our church AC, and everything is now working well.
The company has been professional, dependable, and reputable throughout the process. I had a question after the installation, and it was answered immediately. I also appreciated that they followed up and asked for feedback to make sure the new part was working properly and that we were satisfied with the service.
It’s refreshing to deal with a company that not only has quality products but also cares about its customers after the job is completed. I would definitely recommend them!

The Square D FA32100 circuit breaker (refurbished) was as good as a new breaker, without exception. There was no wear and tear or any marks at all. It was basically new. It is an excellent choice and a great product without having to pay the cost of a new breaker.
