Eaton Cutler-Hammer BR380 80A 3P 240V Circuit Breaker, Type BR, Plug-On | AmpState

The Eaton Cutler-Hammer BR380 is a BR-type, plug-on circuit breaker designed to deliver reliable protection for 3-phase systems. Rated at 80 A and 240 V, this unit is built to fit panelboards, load centers, and electrical distribution setups that rely on BR-series breakers. Its plug-on design makes installation straightforward, helping you speed up retrofit projects and maintenance tasks where preserving the exact part number matters.

• Type: BR (Plug-On)
• Amperage: 80 A
• Poles: 3
• Voltage: 240 V
• Manufacturer: Eaton Cutler-Hammer
• Part Number: BR380

Designed for retrofit work and ongoing maintenance, the BR380 helps maintain consistency across existing installations. When a panelboard or load center was originally equipped with BR-type breakers, replacing with the BR380 ensures compatibility with the bus, mounting, and signaling logic that technicians expect in the field.

Why this BR380 is a practical choice

• Compatibility preserved: Ideal for installations that require staying with the BR family to avoid compatibility issues during service or upgrades.
• Efficient installation: Plug-on mounting reduces installation time and effort, helping you complete service calls faster.
• Clear labeling for maintenance planning: With the exact part number BR380, you can plan replacements and maintain system documentation without guesswork.
• Reliable 3P 240V protection: Safeguards three-phase circuits at 240 V, supporting balanced distribution across industrial and commercial panels.
• Stocked option from AmpState: Readily available to support timely repairs and project timelines.

Who should consider the BR380? Electricians, facilities managers, and maintenance teams responsible for aging or modular panelboards and load centers that use BR-type breakers. It’s particularly well-suited for retrofit projects where maintaining a single, consistent part number simplifies ordering and reduces downtime, and for ongoing maintenance where exact replacements are required to match existing protection schemes.

Practical tips for optimal use:

• Verify that your panelboard supports BR-type breakers before installation, and confirm that three-pole 80 A, 240 V configuration aligns with your circuit requirements.
• Keep the BR380 on hand for planned maintenance to minimize disruption when a replacement is needed.
• When unsure about fit, AmpState offers assistance to confirm compatibility and ensure you pull the correct part for your panel system.

Addressing common questions, the BR380 provides a precise, field-proven solution for protecting 3-phase, 240-volt circuits in Eaton panelboards and related electrical distribution equipment. If you’re maintaining an installation that requires a consistent BR-numbered part, this plug-on 80 A, 3P 240 V breaker is engineered to deliver dependable performance and straightforward service.
