Eaton SPM200480Y1Y Surge Protection Device - 200 kA

Two-module MAX design delivers 200 kA per phase protection, providing robust transient suppression for high-energy surges commonly seen on heavy equipment feeds. This reduces the risk of downstream drive failures, sensor faults, and unplanned outages in motor control centers, switchgear, and processing lines. The modular architecture supports phased protection upgrades, quick field diagnostics, and convenient spare-part stocking for mission-critical applications, helping downtime-sensitive facilities maintain productivity even when power disturbances occur. 277/480 V Wye (4W+G) rating aligns with typical plant power layouts, simplifying panel integration, grounding, and wiring schemes. The configuration supports both line and ground protection without complicating protective coordination, enabling faster commissioning, fewer wiring mistakes, and improved reliability across conveyors, pumps, CNCs, and other heavy loads. NEMA 4X enclosure with internal terminal block provides rugged reliability in damp, dusty, or outdoor environments, and keeps wiring organized in a compact footprint. The integrated terminal block reduces field wiring time, improves termination reliability, minimizes risk of loose connections, and simplifies future maintenance or expansion of protection in evolving facilities. Certifications including UL 1449, UL 1283, CSA, and RoHS compliance demonstrate safety, performance, and regulatory alignment for industrial protection equipment. These standards support risk management, traceability, and smoother customer audits in regulated sectors such as food processing, chemical, and manufacturing facilities. A 15-year warranty (20 years when registered) provides long-term protection and predictable budgeting for maintenance, repair, and replacement cycles. The unit weighs 50 lb and measures 9.3 in deep by 14.91 in wide by 17.5 in high, enabling straightforward handling, mounting, and service in standard electrical rooms.
