Square D HOM115CAFI - 15A, 1-Pole, AFCI Arc-Fault Circuit Breaker

Meet the Square D HOM115CAFI — a 15A, 1-Pole AFCI arc-fault circuit breaker engineered for demanding electrical environments. Designed for use in panelboards, switchboards, and control panels, it delivers reliable overcurrent protection while actively guarding against dangerous arc faults that can lead to fires.

• Arc-fault protection: Quickly detects arcing faults and interrupts the circuit to minimize fire risk, helping keep facilities safer.
• 15-amp, 1-pole design: Ideal for single-hot-conductor circuits in commercial and industrial panels without adding unnecessary complexity.
• Compatibility: Crafted for Square D HOM panel configurations and compatible enclosures in panelboards, switchboards, and motor control centers.
• Industrial-grade reliability: Built to endure the rigors of OEM applications, delivering consistent performance in harsh environments.
• Code-aligned protection: Meets AFCI requirements to support safety standards in commercial and industrial installations.

Practical use cases

• Protect distribution circuits powering lighting and receptacles in warehouses, manufacturing facilities, schools, and other commercial spaces while minimizing nuisance trips from minor arcing events.
• Safeguard control circuits and motor control centers where arc faults could ignite dust, oil, or other flammable materials.
• Upgrade or replace existing AFCI protection in HOM panels to maintain compliant, modern safety performance.

Installation and maintenance tips

• Install in standard Square D HOM-compatible enclosures, ensuring correct alignment with the bus and mounting hardware.
• Use with appropriate panelboard ratings and verify circuit labeling to maintain organized, safe distribution.
• Test the AFCI function regularly as part of a maintenance routine and investigate any trips to identify potential arcing sources or wiring faults before re-energizing.

Why this makes sense for your facility

• Targeted arc-fault protection where it matters most—distribution panels and motor control centers—reducing the risk of electrical fires on critical circuits.
• A straightforward, single-pole 15A solution that delivers AFCI protection without complicating your panel design.
• Designed for industrial, commercial, and OEM applications, offering dependable protection in demanding environments.
