Eaton SPC150240S3P Surge Protection Device - UL 1449

The SPC150240S3P delivers a robust 150 kAIC interrupt rating, providing surge containment for critical loads during transient events. This higher interrupt rating helps prevent cascading failures in downstream equipment, reducing the risk of costly outages and expensive repairs. It is well suited for service entrances, main distribution panels, and outdoor equipment in manufacturing floors or data centers where reliability matters most. With a 120/240 V split-phase configuration, the unit integrates directly with common industrial panels without extensive rewiring. The external side mounting option simplifies installation in crowded enclosures and allows easier replacement or retrofits. This compatibility shortens project timelines and lowers field labor costs while maintaining rigorous protection standards. The NEMA 4X enclosure provides weather resistance and rugged protection for harsh environments, enabling outdoor or damp indoor installations. The combination of enclosure rating and UL 1449 certification supports compliance across facilities that require durable protection in demanding conditions. An audible alarm adds immediate fault notification, so technicians can react promptly to surge events and verify protective performance. This feature reduces mean time to respond and supports proactive maintenance planning, helping minimize unplanned downtime and extend asset life. UL 1449 certification confirms conformance to recognized safety and performance standards, and Eaton backs the SPC150240S3P with a 10-year warranty. The warranty and certification combination supports long-term total cost of ownership reductions, while the device’s tested performance aligns with industry best practices for panel protection and reliability.
