Eaton SPM320240D3W SPD - NEMA 4X Surge Protector
Part Number: SPM320240D3W
Quick Summary
SPD is a surge protection device designed to guard critical electrical systems in industrial facilities against transient overvoltages. Unprotected circuits can suffer equipment damage and unplanned downtime due to lightning, utility switching, and power transients. UL 1449 and CSA listings, along with RoHS compliance, provide safety and regulatory confidence in harsh plant environments. The Eaton SPM320240D3W MAX series delivers robust protection in a NEMA 4X enclosure, with two modules and a 320 kA per phase rating for 240 V delta systems. For panel builders, OEMs, and maintenance teams, this translates to reduced downtime, easier compliance, and longer asset life through reliable surge mitigation.

Special features
Standard with surge counter
The MAX series SPM320240D3W offers a 320 kA per phase surge rating across two modules for 240 V delta systems, enabling high-energy handling during severe transients and delivering fewer nuisance trips for drives, pumps, and controllers on manufacturing lines. This translates to improved process reliability and lower maintenance costs when used in control panels and main switchgear assemblies. The unit comes in a NEMA 4X enclosure with an internal circuit breaker, enabling outdoor or damp environments to meet stringent installation codes while simplifying mounting and wiring in industrial panels. A standard surge counter provides real-time visibility into event history, supporting proactive maintenance and regulatory reporting. RoHS compliance, UL 1449 and CSA listings, and a robust warranty framework reinforce long-term regulatory compliance and asset protection, with a 15-year warranty (20 years when registered) across supported installations.
