Eaton SPM320208Y1U Surge Protection Device - UL 1449
Part Number: SPM320208Y1U
Quick Summary
Eaton SPM320208Y1U surge protection device protects electrical power systems in industrial and commercial panels from transient spikes. When surges occur, sensitive equipment can be damaged, causing downtime and costly repairs; this SPD mitigates interruptions by clamping transient voltages before they reach controls. The unit carries UL 1283, UL 1449 certifications, CSA listings, and RoHS compliance to meet industry safety and environmental standards. With the two-module Max series design in a NEMA 4 enclosure featuring an internal terminal breaker and a built-in surge counter, installation and maintenance are streamlined. Rated for 120/208 V Wye systems and backed by a 15-year warranty (20 years with registration), it aligns with reliability-focused procurement goals and overall TCO reduction.
