BRH2125 - 125 Amp Circuit Breaker

BRH2125 - 125 Amp Circuit Breaker

The Eaton BRH2125 is a 125 Amp two-pole thermal magnetic circuit breaker designed for you to use in compatible Eaton Type BR loadcenters. It provides protection against overloads and short circuits in 120/240V electrical systems and is commonly used for feeder circuits, subpanels, HVAC equipment, electric heating systems, and other larger electrical loads.

With a 22 kAIC interrupting rating, the BRH2125 is intended for installations where available fault current levels exceed the ratings of many standard residential circuit breakers. The common-trip design disconnects both poles simultaneously during a fault condition, helping you ensure that connected equipment and conductors are protected when an overcurrent event occurs.

For facilities already using Eaton Type BR equipment, the BRH2125 provides a compatible replacement option that helps maintain consistency within the existing electrical distribution system.

Where It Works Best

• The BRH2125 is commonly installed in homes, apartment buildings, commercial facilities, retail spaces, workshops, and light industrial properties that utilize Eaton Type BR loadcenters. Typical applications include feeder circuits, subpanel installations, HVAC systems, electric heating equipment, large appliances, and other 120/240V loads requiring 125 Amp two-pole protection.
• It is frequently used during electrical maintenance projects, service upgrades, panel replacements, equipment installations, and new construction where a higher-capacity breaker is required. The 22 kAIC interrupting rating makes it suitable for installations where available fault current levels exceed the capabilities of many standard residential breakers.
