Eaton SPM120600Y4T Surge Protection Device - UL 1449
Part Number: SPM120600Y4T
Quick Summary
The Eaton SPD MAX SPM120600Y4T surge protection device guards critical electrical systems against transient overvoltages in industrial environments. It delivers robust per-phase protection for 347/600 V Wye configurations, helping facilities minimize downtime caused by surge events. Many manufacturers struggle with unpredictable transients that damage drives, relays, and control systems, driving maintenance costs higher. UL 1449 safety certification and a rugged NEMA 4 enclosure ensure reliable performance in harsh factory environments, while the internal terminal block simplifies wiring and serviceability. This protection solution supports scalable protection strategies across sites, and its compatibility with Power Xpert SPD networks helps optimize asset protection and reduce total cost of ownership over time.

High-energy surge protection delivers 120 kA per phase, mitigating the most damaging transients that accompany utility switching and fault events. Business impact: reduced equipment stress, fewer unexpected outages, longer drive lifespans. Application: ideal for motor drives, PLCs, and panel boards in manufacturing lines. 347/600 V Wye compatibility enables direct integration with common industrial feeders without reconfiguration, reducing installation time and minimizing panel rearrangements. This supports a faster project timeline and lowers commissioning costs. Application: data centers, warehouses, and processing lines with four-wire plus ground systems. The NEMA 4 enclosure provides weather and dust resistance, and the internal terminal block streamlines field wiring and future maintenance. Business impact: fewer field modifications and safer, cleaner connections. Application: outdoor or harsh indoor environments where protection class matters. UL 1449 certification confirms safety and performance compliance for surge protection devices, giving procurement teams confidence in regulatory alignment. Coupled with a compact footprint (9.5 in L, 15 in W, 17.05 in H) this unit fits standard racks and on-wall installations, enabling flexible deployment. Power Xpert SPD compatibility enables centralized monitoring and coordinated protection across multiple devices, improving visibility, maintenance planning, and response times across large facilities.
