Schneider Electric | BDA34015Y | Circuit Breaker | 15A | 3-Pole | 277V | 18kA

Meet the Schneider Electric BDA34015Y circuit breaker — a precise, reliable protection solution designed for 277V, three-pole circuits in commercial and industrial panels. Built for retrofit, maintenance, and replacement projects, this breaker delivers dependable performance when the system demands solid short‑circuit protection and stable operation.

Specifications that matter

• Amperage: 15A
• Poles: 3-Pole
• Voltage rating: 277V
• Interrupting rating: 18kA
• Part number: BDA34015Y

Why this breaker stands out

• Dedicated 3‑pole configuration provides balanced protection for multi‑phase circuits, helping prevent nuisance tripping and ensuring coordinated performance with compatible Schneider Electric equipment.
• High 18kA interrupt rating means robust defense against short‑circuit events, reducing potential damage to downstream equipment and wiring in demanding commercial environments.
• Specifically matched to Schneider Electric systems, offering reliable compatibility for maintenance and retrofit projects where exact part reference matters.
• Because the part number is the most reliable compatibility reference, it streamlines ordering and minimizes the risk of mismatch in legacy or upgraded panels.

Ideal use cases

• Retrofits and replacements in existing panels servicing 277V multi‑pole circuits (lighting, power distribution, and related equipment) in office buildings, retail spaces, and warehouses.
• Maintenance cycles where a precise 15A, three‑pole solution is required to maintain circuit protection harmony across a system.
• New installations that follow Schneider Electric specifications for dependable, plug‑and‑play protection with compatible enclosure and bus configurations.

Installation and compatibility guidance

For best results, verify the breaker’s fit with your panel or enclosure by cross‑checking the BDA34015Y part number against the panel catalog. Ensure the bus type and mounting method align with your existing system, and plan for a qualified electrician to perform the replacement or retrofit. Note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

Practical tips and care

• Store spares in a clean, dry area to prevent corrosion on contacts and trip mechanisms.
• During replacement, inspect adjacent breakers and wiring for signs of wear or heat damage; addressing these issues helps prevent future trips.
• Document the replacement with the exact part number (BDA34015Y) and update panel records for future maintenance and audits.
