Eaton’s SPD Series (Sidemount Versions) Data Sheet
Feature: 100 kAIC interrupt rating provides high-energy surge handling with fast response. Business Impact: Maximizes uptime by preventing cascade failures in main distribution panels and critical loads during lightning events or switching transients. Application: Ideal for manufacturing lines, motor drives, and PLC-controlled systems that demand robust transient protection. Paragraph continues with a second feature highlighting 240V delta (3W+G) and 320 L-G / 320 L-L operating voltage for precise protections across line-to-ground and line-to-line faults, reducing nuisance outages in industrial automation networks. A third feature notes the NEMA 4X enclosure and external side mounting, enabling durable installation in wet, dusty, or wash-down environments. A fourth feature cites UL 1449 certification for safety compliance and streamlined procurement, while a final feature emphasizes a 15-year warranty and standard feature package to lower lifecycle costs and ensure long-term reliability in asset-heavy facilities.

FAQs
SPD100240D2O supports external side mounting, making it easy to install on existing panels without internal equipment modifications. The footprint (9.5 in length, 5.4 in width, 3.45 in height) fits many standard enclosures, while the NEMA 4X rating protects against dust and moisture. Follow Eaton’s installation manual for proper wiring and clearances to ensure code-compliant performance.
The device offers a 100 kAIC interrupt rating and a 240V delta (3W+G) input with 320 L-G and 320 L-L operating voltages. This combination provides robust protection for downstream controllers, drives, and sensors against high-energy transients, especially in facilities with frequent switching or lightning events.
Yes. The model is designed for external side mounting to electrical distribution equipment, enabling retrofits and space-constrained installations. When retrofitting, adhere to the IM01005031E installation manual, verify enclosure integrity, and ensure grounding and conductor sizing meet local electrical codes for a safe, compliant upgrade.
SPD100240D2O carries UL 1449 certification, confirming recognized safety compliance. The enclosure is NEMA 4X-rated, suitable for wet and dusty environments. While CE certification is not listed in the provided data, UL 1449 certification supports procurement in many regulated facilities. Always reference the datasheet for your specific compliance requirements.
The product includes a 15-year warranty, which helps reduce lifecycle costs and provides long-term reliability. By protecting critical loads such as drives and PLCs, it minimizes unplanned outages and maintenance charges. The combination of robust surge protection and straightforward installation supports faster project timelines and a lower total cost of ownership over the asset life.
