Eaton SPD100208Y3A Surge Protection Device - UL 1449 Listed
Part Number: SPD100208Y3A
Quick Summary
The Eaton SPD100208Y3A surge protection device provides fast transient suppression for 120/208V power networks in commercial and light industrial panels. For engineers and maintenance teams, unpredictable surges cause downtime and equipment damage; this device reduces that risk with reliable protection. It carries UL 1449 Listed certification and delivers EMI/RFI filtering with up to 50 dB attenuation from 10 kHz to 100 MHz, while aligning with IBC 2006, CBC 2007, and UBC Zone 4. An audible alarm with silence button, Form C relay contact, and an integrated surge counter simplify diagnostics and quick response. Designed for Direct bus mounted panelboards PRL1a, 2a, 3a, 3e, it enables rapid deployment and consistent, site-wide protection across multiple panels.

High surge capability provides robust protection for critical loads at 100 kA per phase, with a 200 kAIC short-circuit rating, reducing the likelihood of drive or PLC damage and shortening unplanned downtime in 120/208V systems. This translates to lower repair costs and higher plant availability, especially in multi-panel deployments leveraging Direct bus mounted configurations. Nominal discharge current of 20 kA RMS ensures fast clamping of frequent, smaller surges, minimizing nuisance trips and extending motor and drive life for servo systems and automation equipment. Internal mounting and a compact footprint simplify installation in crowded panels, enabling faster retrofits and scalable protection as facilities grow. An audible alarm with silence button and a surge counter provide immediate on-site awareness and traceable maintenance data, reducing diagnostic time. EMI/RFI filtering up to 50 dB between 10 kHz and 100 MHz improves control stability for PLCs and drives, supporting compliant, noise-free operation. With 50/60 Hz operation, -40 to 50 °C ambient range, a 15-year warranty, UL listing, and Direct bus compatibility, the SPD1020 family offers predictable lifecycle costs and long-term reliability for mission-critical panels.
