Eaton BR240 Type BR Circuit Breaker - 120/240V, 40A, 2-Pole, 10kA

Overview

The Eaton BR240 Type BR circuit breaker is crafted for 120/240 VAC panels, delivering a reliable 40 A two-pole protection solution. With a common-trip design and a thermal-magnetic trip mechanism, it responds quickly to overloads and short circuits, helping safeguard connected equipment and wiring in residential and light commercial settings.

Why this matters

In daily electrical use, predictable protection matters. The BR240 is built to operate within standard BR-panel configurations, offering a familiar form factor and straightforward replacement when needed. The two-pole arrangement ensures both hot conductors disconnect together, reducing the risk of undetected fault currents in shared-neutral or multi-wire circuits.

• Protection for 120/240 VAC circuits
• Two-pole design with common trip for synchronized disconnection
• Thermal magnetic trip provides fast response to overloads
• 10 kA interrupting rating supports high fault current environments

The two-pole design is well suited for multi-wire branch circuits where simultaneous disconnection improves overall safety. Its robust interrupting capability makes it a practical choice in environments with higher fault current potential, such as shared residential panels or light commercial setups.

How to choose and install

Match the BR240 to a BR-series panel and verify the slot and bus compatibility. Consider the overall panel layout, available space per pole, and whether you need a single dedicated circuit or a segment of multi-circuit protection. Always de-energize the panel before handling, and consult a licensed electrician if you are uncertain about sizing or mounting requirements. Proper torque on the terminal screws and correct enclosure clearance help maintain reliable performance over time.

Final note

The BR240’s combination of voltage rating, current capacity, and fast-acting trip behavior makes it a practical option for users seeking dependable circuit protection without complicated configuration. By integrating this two-pole breaker into compatible BR-series panels, you gain a straightforward, familiar path to safeguarding essential circuits and improving overall electrical safety.
