Eaton SPD100240D3Q Surge Protection - UL 1449
Part Number: SPD100240D3Q
Quick Summary
SPD100240D3Q surge protection device provides reliable surge protection for 240V delta three-phase systems in industrial facilities. Engineers often struggle with costly downtime and equipment damage caused by transient voltage spikes, and this SPD helps minimize outages by diverting spike energy away from critical loads. UL 1449 listed, a NEMA 4X stainless enclosure, and a 100 kAIC interrupt rating deliver certified protection in harsh environments and long service life. With external sidemount installation and a compact footprint, it supports straightforward retrofits in existing switchgear while enabling scalable protection for control panels, motors, and distribution equipment. This combination aligns with industrial power quality objectives, reducing maintenance costs and improving system reliability.

FAQs
Yes. The SPD100240D3Q is designed for external sidemount installation, which simplifies retrofits in existing electrical distribution equipment. Its compact footprint (9.5 in L × 5.4 in W × 3.45 in H) and stainless steel NEMA 4X enclosure support flexible mounting while maintaining accessibility for maintenance and surge counting without disrupting adjacent components.
The 100 kAIC (ampere interrupting capacity) rating indicates the maximum surge current the device can safely interrupt without internal damage. This level provides robust protection against high-energy transients common in industrial facilities, reducing the risk of insulation breakdown, equipment damage, and downstream failure of drives, transformers, and control electronics.
Industries with demanding power quality needs—manufacturing, automation, and process control—benefit most. The SPD protects motors, distribution panels, and control systems in 240V delta (three‑phase with ground) networks. Its rugged enclosure and sidemount capability make it ideal for harsh environments, outdoor installations, and retrofit projects in metal fabrication, packaging, and water treatment facilities.
The SPD100240D3Q is UL 1449 listed, assuring compliance with recognized surge protection standards. This certification supports safety and reliability expectations for electrical protection devices. The NEMA 4X stainless enclosure further reinforces suitability for challenging environments, including exposure to moisture and corrosion, while maintaining dependable performance.
Maintenance is simplified by the built-in surge counter, which provides ongoing event tracking to plan proactive service or replacements. The rugged enclosure, long warranty (15 years), and high surge rating translate to lower downtime and extended service life, delivering a favorable total cost of ownership for facilities seeking reliable power protection and reduced maintenance surprises.
