Eaton BR270B – Frequently Asked Questions

1) Will an Eaton BR270 breaker fit my Cutler-Hammer/Eaton BR load center?
The BR270 is a plug-on breaker built for Type BR loadcenters, so it snaps onto the bus of an Eaton (formerly Cutler-Hammer) BR panel with no mounting hardware. It will not fit a CH panel or another manufacturer's panel - the BR and CH bus stabs are different breaker families, so check the panel label for BR before ordering.
2) What wire size can I land on this 70 amp 2-pole Eaton BR breaker?
Lug range is #8 through 1/0 AWG, and the lugs are rated for both copper and aluminum conductors. That covers the usual 70A feeder conductors - #4 copper or #2 aluminum - with headroom up to 1/0 if you're upsizing for voltage drop on a long run.
3) What is the difference between the BR270, BR270B and BR270CS?
Same 70A two-pole BR breaker in all three; the part number reflects packaging. BR270 is the load-center version (also referenced as an alternate code), BR270B is the standard pack, and BR270CS is the clamshell retail pack. Electrically and dimensionally they're the same device, so buy on how you want them delivered - bulk for a panel build, clamshell for counter or truck stock.
4) Does this two-pole Eaton BR breaker trip both hot legs together?
Yes - it's a common trip design, so a fault or overload on either pole opens both legs at once. That's what's required for a 240V load like a water heater, well pump, or A/C condenser, as opposed to two handle-tied single poles.
5) Can I use this Eaton 70A breaker on a 208Y/120 three-phase panel?
It's rated 120/240V. On a 208Y/120 system the line-to-line voltage is 208V, which is within that rating for a two-pole application, but the breaker itself is a Type BR plug-on device made for BR loadcenters, not for three-phase panelboards using a different bus. Match it to a BR loadcenter and stay inside the 120/240V rating.
6) Does this breaker meet code listing requirements for a commercial job spec?
It's UL 489 listed as a molded case circuit breaker and carries Federal Specification classification W-C375, which is the language most institutional and government specs reference for branch and feeder breakers. Those are the two compliance marks on record for the Eaton BR 70A two-pole.
7) How many spaces does a 70A two-pole BR breaker take in the panel?
A two-pole BR breaker occupies two full spaces in the loadcenter, landing on both bus legs so it sees 240V. Before ordering, count two open adjacent full-size spaces - if the panel only has tandem-filled or single remaining spaces, you'll need to rework the circuits to make room.
