Eaton SPD100600Y3A Surge Protection Device - UL Listed

The SPD100600Y3A delivers a 100 kA per phase surge rating and a 200 kAIC short‑circuit rating, providing robust defense for feeders, drives, and sensitive digital loads. This protection minimizes nuisance outages, data loss, and equipment damage in industrial control panels and switchgear assemblies. The device is rated for 347/600 V (4W+G) with a 50/60 Hz frequency, enabling broad compatibility in mixed‑voltage facilities and motor starter circuits. EMI/RFI filtering provides up to 50 dB of attenuation from 10 kHz to 100 MHz, improving power quality for PLCs and HMIs. It also supports Direct bus mounted panelboards per PRL1a, 2a, 3a, and 3e, simplifying integration into existing architectures. The internal mounting reduces enclosure space and eliminates external hardware, accelerating protection deployment in retrofit projects. The footprint is 9.5 in L × 5.4 in W × 3.45 in H with a 3.5 lb weight, easing handling during installation. A surge counter with a rest button and an audible alarm (with silence option) provide immediate visibility and easy maintenance planning during routine checks. Form C relay contacts enable remote signaling to plant controllers or building management systems, supporting automated responses such as safe shutdowns or alert notifications when surges occur. With a wide operating temperature range of -40 to 50 °C, this SPD maintains performance in harsh factory environments, including areas with temperature extremes. The unit’s 15‑year warranty and UL 1449 listing reinforce long‑term reliability for critical electrical protection programs, while its compact, integrated design reduces total installed cost and simplifies code‑compliant installations. In practice, this translates to improved uptime, reduced spare‑parts inventory, and a clearer path to regulatory compliance for industrial facilities.
