80 Amp 3 Pole Standard BR Circuit Breaker · Eaton BR380
What this product is for
The Eaton BR380 is a Type BR plug-on circuit breaker used to provide branch circuit overcurrent and short-circuit protection in compatible Eaton BR loadcentres and panelboards. It is built for 240V AC applications requiring an 80A, 3-pole common-trip breaker.
Use for
Use for listed Eaton Type BR panel applications, including light commercial and residential distribution where a 3-pole 80A breaker is specified. Typical uses include panelboard branch circuits, equipment disconnecting means where permitted, and multi-pole loads requiring common trip.
Avoid for
Avoid using this breaker in panels not specifically listed for Type BR breakers. Do not substitute it for higher interrupting rating models such as BRH series where available fault current requires more than 10 kAIC.
Best for
Best for electricians replacing or specifying an Eaton Type BR 80A 3-pole breaker in compatible 240V distribution equipment. It suits jobs where plug-on installation, common trip, and standard 10 kAIC branch protection are required.
Installed in
Installed in Eaton Type BR loadcentres and panelboards using a plug-on mounting format. Confirm panel listing, available fault current, conductor size, and local code requirements before ordering or installation.
Why this product exists
This breaker provides a listed Type BR replacement and new-install option for 3-pole 80A branch protection in Eaton BR systems. It helps contractors match breaker type, pole count, ampacity, and interrupt rating to the panel and circuit design.
Compared with similar products
Compared with higher interrupting Type BRH versions, the BR380 is the standard 10 kAIC option. Compared with 2-pole breakers, this model provides 3-pole common-trip protection for three-phase or other multi-pole applications. Selection should be based on panel compatibility and fault-current requirements, not amp rating alone.
