Eaton SPD100240S3Q Surge Protection Device - UL 1449
Part Number: SPD100240S3Q
Quick Summary
SPD100240S3Q surge protection device is designed to guard 120/240 V electrical systems against transient events in industrial and commercial environments. Unprotected spikes can cause outages, erratic equipment behavior, and costly repairs; this SPD helps prevent those interruptions by diverting surge energy away from sensitive loads. UL 1449-listed protection with a rugged NEMA 4X stainless-steel enclosure provides reliable performance in harsh environments, while external sidemount installation simplifies retrofits. Beyond protection, the unit’s 15-year warranty and built-in surge counter offer long-term value, supporting reliable, compliant deployments in electrical protection and control networks across facilities.

100 kAIC interrupt rating delivers robust line-side defense against high-energy transients, protecting downstream loads from damage and reducing unplanned downtime. The SPD100240S3Q clamps surges before they reach sensitive components, extending the life of motors, drives, and controllers, translating into fewer outages and lower replacement costs in manufacturing and critical facilities. The NEMA 4X stainless steel enclosure with internal disconnect provides reliable protection in wet, dusty, and outdoor environments, while external sidemount installation simplifies retrofits and minimizes panel work. A standard feature package includes a surge counter to track events and facilitate maintenance planning, with diagnostics that support quick health verification during rounds or remote monitoring. Operating across 120/240 V with 150 L-N, 150 L-G, 150 N-G and 300 L-L configurations, it fits broad distribution needs without custom engineering. The combination of UL 1449 certification and a 15-year warranty underpins long-term reliability, reducing total cost of ownership for control rooms and distribution boards.

FAQs
SPD100240S3Q features external side mounting and a compact footprint (9.5 in L x 5.4 in W x 3.45 in H) that fit common distribution panels. The stainless steel, NEMA 4X enclosure includes an internal disconnect for straightforward wiring and safe commissioning. Follow the Eaton installation manual for recommended clearances and torque specs to ensure optimal performance.
The device provides a 100 kAIC interrupt rating for high-energy surges and supports a 120/240 V system. It protects across L‑N, L‑G, N‑G, and L‑L configurations, enabling reliable protection for a wide range of industrial and commercial loads without changing upstream infrastructure.
Yes. The SPD is housed in a stainless steel NEMA 4X enclosure with external sidemount mounting, designed to withstand exposure to water, dust, and other challenging conditions. This makes it suitable for outdoor installations and rugged industrial environments where enclosure integrity is critical for continuous protection.
SPD100240S3Q is UL 1449 listed, confirming compliance with established surge protection standards. Its rugged enclosure and internal disconnect reinforce safe operation in harsh environments, while a 15-year warranty provides long-term support and service confidence for mission-critical protection in electrical protection and control networks.
The integrated surge counter enables proactive maintenance by documenting surge events, while the 100 kAIC protection reduces the likelihood of downstream component damage. Combined with UL certification and a long warranty, you can expect lower downtime, extended asset life, and predictable maintenance budgets across industrial panels and distribution equipment.
