100 kA per phase
With a surge current rating of 100 kA per phase, SPD100240S4C dramatically reduces the risk of transient damage to connected equipment. In real-world panel setups, that protection translates to fewer fuse blows and longer service life for motors, drives, and control electronics. This device is designed for 120/240V split-phase systems in switchboards, busways, and panel boards, enabling quick integration into existing architectures while supporting future expansion. Compatibility with Power Xpert SPD accessories simplifies installation and ongoing maintenance, allowing contractors to standardize protection across multiple panels and configurations. The compact footprint (3.48 in depth, 12.05 in height, 7.47 in width) and a 6.8 lb weight improve installation flexibility in crowded enclosures, reducing project time and labor costs. UL 1449 listing provides regulatory assurance and risk reduction for uptime-critical environments.Additional value comes from its targeted use with PRL series panels (PRL1a, 2a, 3a, 3e, 4), ensuring consistent protection across switchboards and busways. The 100 kA per phase rating supports critical loads such as drives, PLCs, and control cabinets, delivering measurable improvements in equipment reliability and reduced maintenance frequency. By combining the Power Xpert SPD accessory ecosystem with Eaton’s proven protection platform, facilities managers gain a scalable, maintainable solution that aligns with reliability targets and budget discipline.
