Cutler-Hammer BR115AF - 15A, 1-Pole, AFCI Arc-Fault Circuit Breaker

The Cutler-Hammer BR115AF is a 15A, 1-Pole AFCI Arc-Fault Circuit Breaker engineered for demanding industrial, commercial, and OEM panel installations. Designed to integrate with the Cutler-Hammer BR family, it delivers dependable overcurrent protection while adding arc-fault sensing to help guard against dangerous arcing conditions in wiring.

Designed for flexible, space-conscious installations, this 1-Pole configuration is ideal for panelboards, switchboards, and control panels where compact protection matters. It’s purpose-built for distribution panels and motor control centers, delivering reliable interruption for circuits under load and during fault events.

• Current rating: 15 A
• Poles: 1-Pole
• Breaker type: AFCI Arc-Fault Circuit Breaker
• Applications: panelboards, switchboards, and control panels in industrial, commercial, and OEM environments
• Use case: provides arc-fault protection on branch circuits feeding equipment, lighting, and control loads in distribution panels and motor control centers
• Key differentiator: adds arc-fault detection to standard overcurrent protection, helping to reduce fire risk from arcing due to loose connections, damaged insulation, or worn wiring

Why this matters in real-world setups: in busy industrial facilities or commercial spaces with heavy motor loads, arc faults can occur intermittently and go unnoticed until a dangerous fault develops. The BR115AF detects both series and parallel arcs, interrupting the circuit quickly to protect wiring and equipment. For OEM designers, it offers a reliable, space-efficient solution that plugs into BR-series control architectures without redesigning panels.

Practical use scenarios include protecting feeders and branch circuits in machine tool enclosures, conveyors, lighting racks, and other control-panel environments where space is at a premium and safety is non-negotiable. If you’re upgrading from a standard 15A breaker in a BR-panel to add arc-fault protection, the BR115AF provides a straightforward, compatible upgrade path that enhances safety without sacrificing layout or performance.
