Cutler-Hammer ELFD3015L Circuit Breaker, 15A, 3-Pole, 480V

Meet the Cutler-Hammer ELFD3015L — a purpose-built circuit breaker engineered for industrial electrical service, maintenance, and replacement projects. With a 15 A rating, this 3-pole unit is designed to reliably interrupt 480V three-phase systems, safeguarding equipment and personnel in demanding plant environments. As part of the ELFD family, it integrates seamlessly into compatible ELFD panelboards and distribution gear, delivering dependable protection where it’s needed most.

• Three-pole protection — ensures coordinated shutdown of all phases in three-phase circuits, helping prevent unbalanced faults and protecting connected motors and load for smoother operation.
• 480V industrial compatibility — built to handle typical high-voltage distribution needs found in manufacturing, processing, and automation facilities.
• Precise 15A protection — provides targeted safeguarding for equipment with moderate current draw while reducing nuisance trips during normal startup surges.
• ELFD series compatibility — designed for straightforward integration into ELFD-based installations; verify fit by part number and application requirements to ensure a perfect match.
• Efficient maintenance and replacement — engineered for quick swap-ins in service or upgrade scenarios, minimizing downtime and keeping critical lines energized safely.

Use cases for this breaker include replacing a worn unit in a 480V three-phase feeder, upgrading an existing ELFD panel to provide reliable 15A circuit protection, or adding a dedicated branch circuit for equipment within an industrial distribution system. This part is specifically identified by the part number ELFD3015L, so a quick compatibility check against your panel and application requirements is essential.
