Starline

What Starline does

Starline, headquartered in Canonsburg, Pennsylvania, manufactures modular overhead open-channel track busway systems for flexible power distribution in data centers, industrial manufacturing, EV charging, laboratories, and commercial facilities. The company's core product line spans Track Busway (40A–1200A), the IP54-rated Series-S Busway for harsh and liquid-cooled environments, and High Power Busway (Series HP and XCP) for high-amperage data center applications above 1500A. These systems allow power access points to be repositioned in minutes via hot-swappable plug-in units rather than requiring rewiring, with the Remote Plug-In Actuator enabling safe engagement from outside the arc flash boundary. Complementary products include the M70, M40, and M50 Critical Power Monitors (integrating with BMS and DCIM platforms via BACnet, Modbus, and SNMP), Plug-In Raceway, and metering accessories.

Founded in 1935 and acquired by Legrand in 2021, Starline operates as a brand within Legrand North and Central America with a sales model built on local reps, enterprise field sales, direct website quote requests, and bundling through the Legrand distribution ecosystem. Revenue is generated primarily through customized quote-based hardware sales of busway components and CPM devices, supplemented by value-added services such as commissioning, equipment rentals, meter programming, on-site support, and extended warranty plans. The company carries UL857 certification for busways, supports live-insertion grounding, and publishes extensive technical content (white papers, case studies, webinars) targeting consulting engineers and facility operators. Starline serves named enterprise customers including a Tier I automotive supplier in Texas, a Michigan-based automaker, JE Dunn Construction, and Butler Country Club, while targeting hyperscale, colocation, and enterprise data centers as the strategic growth segment driven by AI and high-density compute deployments.
