Eaton SPM250400Y1T Surge Protection Device - RoHS Compliant
Part Number: SPM250400Y1T
Quick Summary
The Eaton SPM250400Y1T surge protection device guards electrical systems against transient overvoltages in industrial panels. Unprotected equipment can suffer costly downtime, nuisance tripping, and premature component wear due to voltage spikes from switching events or grid disturbances. This model carries critical certifications including UL 1449, UL 1283, and CSA listings, with RoHS compliance ensuring hazardous substances are managed. The device is designed for 230/400 V Wye configurations (4W+G) and comes in a NEMA 4 enclosure with an internal terminal breaker, delivering reliable protection in harsh environments while enabling straightforward installation. For engineers and procurement teams, this translates to minimized risk, longer equipment life, and lower total cost of ownership when deployed in control panels and switchgear assemblies.

Special features
Basic
The SPM250400Y1T is engineered to deliver 250 kA per phase protection, reducing the risk of dramatic transient events causing downstream gear failure and unplanned outages. This high surge rating translates to measurable business value by extending motor life, protecting sensitive drives, and cutting maintenance costs for automated lines in manufacturing facilities. Installed in 230/400 V Wye systems, it supports common industrial distributions while staying compatible with standard panel layouts, simplifying retrofits and new builds alike. The NEMA 4 enclosure with internal terminal breaker provides robust dust and moisture resistance, enabling reliable operation in factory floors and outdoor or semi-exposed installations. RoHS compliant construction aligns with modern compliance programs, while UL and CSA certifications offer regulatory confidence for safety-critical applications. With a basic configuration in the Max series, the SPD offers predictable performance and straightforward field servicing, reducing downtime during maintenance windows. This solution is especially advantageous for data centers, packaging lines, and machine builders seeking proven surge protection without complex integration or costly custom solutions.
