BRX2125 - 125 Amp Circuit Breaker Description
BRX2125 - 125 Amp Circuit Breaker
The Eaton BRX2125 is a 125 Amp two-pole thermal-magnetic circuit breaker designed for you to use in compatible Eaton BR loadcenters and panelboards. It provides overload and short-circuit protection for your 120/240-volt electrical systems and is commonly installed as a main breaker, feeder breaker, or equipment disconnect in residential, commercial, and light industrial applications.
Rated for 65 kAIC, the BRX2125 is often used in systems where available fault current is higher than the interrupting capacity of standard branch circuit breakers. It is commonly found in service entrance equipment, distribution panels, subpanels, and feeder circuits that require a higher fault-current rating.
With support for wire sizes from #14 through 2/0 AWG and a compact two-pole footprint, the BRX2125 is frequently used for service upgrades, panel replacements, equipment retrofits, tenant improvements, facility maintenance projects, and new construction where compatibility with Eaton BR equipment is required.
