Special features
Basic
High surge capacity delivers 120 kA per phase, enabling reliable protection for high-energy transients and minimizing the risk of equipment damage in 277/480 V Wye systems. This directly improves overall plant reliability and extends the life of drives, PLCs, and sensors, reducing unplanned downtime for manufacturing lines and automation systems. The single-module design paired with an internal terminal block simplifies wiring and reduces panel space, accelerating commissioning and enabling faster deployments in retrofits and new builds. The NEMA 4X enclosure provides weather- and washdown-resistance, ensuring protection in demanding environments such as outdoor equipment rooms and wet process areas, which translates to lower field maintenance costs. Compliance with RoHS and standard safety certifications assures procurement teams and compliance managers of long-term regulatory alignment. The 15-year warranty (20 years with registration) offers a tangible return on investment through extended asset protection, fewer replacements, and improved total cost of ownership. Compatibility with Eaton’s SPD ecosystem supports seamless integration with existing protection schemes and service agreements.

FAQs
The SPM120480Y1X is a single-module SPD designed for straightforward integration into 277/480 V Wye systems. Its internal terminal block simplifies wiring, while the NEMA 4X enclosure accommodates installation in harsh environments. Ensure compatible panel spaces and proper clearance around the unit, and follow the provided Eaton installation guidelines to maintain warranty and performance.
A 120 kA per phase rating indicates a high surge handling capacity, allowing the SPD to absorb large transient events without reaching its protective limits. This reduces the likelihood of downstream component damage in drives, PLCs, and sensors, which translates to lower repair costs, less downtime, and longer equipment life in automation lines and control cabinets.
Yes. The unit uses a NEMA 4X enclosure that provides weather resistance and washdown capability, making it suitable for outdoor installations and challenging environments like manufacturing floors or outdoor switchgear rooms. The internal terminal block further protects connections from corrosion and vibration, improving reliability in harsh conditions.
This SPD is UL 1449 and UL 1283 listed, and CSA C22.2 No. 8-M1986 certified, with RoHS compliance. These certifications confirm safety, performance under surge conditions, and environmental responsibility, helping ensure regulatory alignment for industrial electronics, facility upgrades, and compliance-driven procurement.
The combination of 120 kA per phase protection, rugged NEMA 4X enclosure, and a 15-year warranty (20 years with registration) supports a strong ROI by reducing fault-related downtime and asset replacements. Routine visual inspections and periodic functional checks per Eaton guidelines are typically sufficient; overall, this drives lower lifecycle costs and predictable maintenance planning.
