Eaton SPM320240H1W Surge Protection Device - UL 1449

Two-module design delivering 320 kA per phase provides robust protection for critical loads, minimizing equipment damage, reducing unscheduled downtime, and lowering maintenance costs in high-demand facilities such as stamping presses, CNCs, and packaging lines. This configuration is ideal for manufacturing floors and power-distribution panels facing frequent transients. The 240 delta (4W+G) high-leg configuration is tailored to common industrial power architectures, providing accurate protection on each phase while maintaining correct surge paths. It enables predictable clamping behavior, simplifies electrical design, reduces nuisance tripping, and improves coordination with upstream protection devices for delta-wired motors, drives, and control circuits across factories, warehouses, and process lines. The NEMA 4X enclosure with an internal circuit breaker delivers rugged protection in harsh environments and enables simple field isolation, lowering installation cost by reducing additional enclosures and external devices while supporting serviceable paths during maintenance windows. It installs in outdoor racks, wet rooms, or dirty facilities where ingress protection and quick de-energization are essential. The unit’s standard surge counter provides visible indication and traceability of events, supporting proactive asset management, quick fault diagnosis, and compliance reporting to meet maintenance SLAs for instrumentation panels and SCADA-ready controls requiring event logging in energy-management and safety-critical systems. RoHS compliance, UL 1449, UL 1283, CSA approvals, and a 15-year warranty (20 years with registration) give assurance, minimize regulatory risk, and protect long-term ROI through extended protection lifespans in regulated industries, data centers, and facilities seeking durable, standards-aligned surge protection with strong vendor support.
