Eaton SPD100220Y1M Surge Protection Device - UL 1449
Part Number: SPD100220Y1M
Quick Summary
SPD100220Y1M surge protection device protects electrical systems from transient surges in industrial panels. Frequent voltage spikes cause unexpected equipment failures, downtime, and maintenance headaches that erode productivity and budget accuracy. UL 1449 listing backs safety and reliability, while a 15-year warranty reinforces long-term protection; its NEMA 1 enclosure and external side mounting simplify installation in harsh environments. Designed for 127/220V Wye (4W+G) distributions with a 100 kAIC interrupt rating, it fits modern control architectures and supports compliant protection strategies. By consolidating protection into a compact unit, it helps reduce replacement costs and accelerates commissioning for OEMs and end users.

FAQs
SPD100220Y1M is designed for external side mounting in indoor NEMA 1 enclosures. Ensure adequate clearance for accessibility, allow space for the internal disconnect if present, and verify that mounting hardware matches the enclosure’s mounting pattern. Plan wiring to L-N, L-G, N-G, and L-L paths with short, well-organized conductors to minimize impedance and maximize surge protection efficiency.
Yes, SPD100220Y1M is rated for 127/220V Wye (4W+G) configurations and provides a 100 kAIC interrupt rating. In practice, this enables robust protection for typical industrial control circuits, motor drives, and PLC power feeds. For best results, coordinate with upstream protection devices and ensure proper coordination with downstream breakers to maintain selective protection during faults.
The device offers high-energy surge handling (100 kAIC), a compact NEMA 1 enclosure, and external side mounting for easier retrofits. Benefits include reduced downtime from surge events, longer equipment life, and simplified compliance with UL 1449 standards. Its basic feature package keeps initial costs manageable while delivering essential protection for critical equipment in harsh production environments.
SPD100220Y1M carries UL 1449 listing, validating its surge protection capability and safety performance. It uses a robust NEMA 1 enclosure suitable for indoor use, and is backed by a 15-year warranty, signaling long-term reliability and support for extended asset lifecycles in industrial settings.
Maintenance is typically minimal due to passive protection design, with routine inspections of wiring integrity and enclosure seals. ROI stems from reduced unplanned downtime, extended equipment life, and lower replacement costs. The 15-year warranty further lowers total cost of ownership by providing long-term protection without frequent replacements.
