Eaton SPM120600D4T Surge Protection Device - UL 1449

High surge current capability delivers 120 kA per phase, providing robust protection for motor drives and critical loads. This reduces the risk of equipment damage from voltage transients and minimizes unplanned downtime, translating into lower maintenance costs. It is well suited for 3W+G configurations in switchgear, MCCs, and panelboards where rapid transient suppression is essential. 600 Delta (3W+G) configuration aligns with common industrial grounding practices and simplifies protection coordination with upstream devices. Clear wiring and standardized layout enable reliable fault analysis and faster commissioning. In practice, engineers deploy this SPD Max Series across Power Xpert protection schemes in manufacturing lines and process plants with confidence. UL 1449 listing and a rugged NEMA 4 enclosure deliver compliance and durability for challenging environments. The combination reduces enclosure upgrades and supports both indoor and outdoor installations, including damp locations. This protection helps facilities meet regulatory expectations while sustaining uptime in demanding industries such as food and beverage, logistics, and automation. Internal terminal block simplifies installation and maintenance by reducing field connections and potential contact resistance. Mounting is straightforward inside standard panels, saving labor time during upgrades and spares management. Technicians appreciate the predictable wiring scheme and reduced commissioning delays when integrating this SPD into existing Power Xpert SPD networks. Robust physical dimensions and weight—9.5 in depth, 17.05 in height, 15 in width, approximately 52 lb—support stable mounting in compact electrical rooms. The sturdy construction resists vibration and customer requirements for long service life. Paired with UL safety standards, this device delivers dependable protection across industrial facilities with stringent uptime requirements.
