Eaton SPD100220Y1K Surge Protection Device - UL 1449
Part Number: SPD100220Y1K
Quick Summary
SPD100220Y1K is a surge protection device designed to safeguard electrical distributions in industrial and commercial panels. When voltage transients spike, unprotected equipment such as PLCs, drives, and motors can suffer damaging faults and costly downtime. UL 1449 listing ensures compliance with essential safety standards, while the NEMA 1 enclosure provides indoor protection and secure mounting; the external sidemount design simplifies retrofits. This solution helps reduce maintenance costs and extend asset life, delivering reliable protection for critical systems and enabling smoother operations in harsh industrial environments. In addition to basic protection, devices in this family offer compatibility with external equipment and fast installation, helping engineers meet project schedules and budget targets.

FAQs
SPD100220Y1K uses an external sidemount design and a NEMA 1 enclosure, which simplifies retrofits inside standard electrical cabinets. Ensure adequate clearance for heat dissipation, follow the included installation manual, and verify 127/220 V Wye configuration compatibility with existing feeders. Plan for minimal wiring length to reduce impedance and ensure proper grounding for effective surge suppression.
With a 100 kAIC interrupt rating, the device can safely absorb high-energy surges without transferring damaging energy to protected loads. The 127/220 V Wye rating supports common industrial power supplies, protecting PLCs, drives, and control panels from lightning-induced transients and switching spikes, thereby reducing the risk of unexpected equipment failures.
SPD100220Y1K is designed for 127/220 V Wye systems and is part of Eaton’s SPD Series with a sidemount configuration. While it is optimized for Eaton protection strategies, it can be integrated into mixed-panel environments where standard 127/220 V wiring is used. For IEC-specific setups, confirm voltage compatibility and mounting access prior to installation.
The SPD100220Y1K carries UL 1449 listing, confirming surge protection performance and safety compliance. The device is housed in a NEMA 1 indoor enclosure and is designed for external sidemount installation, supporting reliable protection in standard indoor electrical rooms and panels.
By reducing transient-related outages and protecting critical equipment, SPD100220Y1K can lower maintenance costs and extend asset life. The 15-year warranty adds long-term value, while 100 kAIC protection and UL 1449 certification support compliance and reliability, delivering a favorable total cost of ownership, especially in plants with frequent power disturbances.
