Eaton SPD100240S3H Surge Protection Device - UL Listed
Part Number: SPD100240S3H
Quick Summary
SPD100240S3H is a surge protection device engineered to guard electrical systems in panelboards against transient overvoltages. Too often, unexpected surges drive costly downtime and equipment damage in industrial facilities. It carries UL 1449 and UL 1283 certifications and is UL Listed, with EMI/RFI filtering to reduce noise. Rated for 120/240 V split single-phase service and 50/60 Hz operation, it integrates easily with existing panel layouts, delivering reliable protection with a built‑in surge counter. This combination supports compliant design practices and simplifies procurement for electrical engineers and maintenance teams. Additional benefits include enhanced equipment longevity and improved protection against nuisance tripping in controlled environments. Engineers appreciate predictable performance under 50/60 Hz operation and robust UL-listed protection across code-conforming installations.

High interrupt rating of 200 kAIC and nominal discharge current of 20 kA per phase provide a robust energy-handling margin, reducing the likelihood of protective element failure during large transients. This translates to fewer replacements, lower maintenance costs, and minimized downtime for critical loads in manufacturing lines and data-centers. The SPD’s 120/240 V split single-phase rating and 50/60 Hz compatibility ensure seamless integration with common panelboards, facilitating rapid deployments in retrofit or new-build projects. EMI/RFI filtering up to 50 dB attenuates noise from switching devices and drives, improving PLC and drive performance and prolonging sensor accuracy. An internal surge counter with a rest button, together with a Form C relay contact and audible alarm with silence, delivers clear fault signaling and easy remote integration. The device ships with a standard feature package, including a robust mounting approach and an aspirational compliance profile with IBC/CBC/UBC Zone 4 considerations, making it suitable for regulated industrial environments. Quick maintenance checks are supported by the counter and visible indicators, reducing time-to-restore after events. Using this SPD with panelboards (PRL-C) streamlines procurement, as a single protection solution covers both main power quality and downstream electronics, yielding measurable reliability gains and lower total cost of ownership.
