High surge capacity and 100 kAIC interrupt rating deliver robust protection for sensitive loads in industrial systems. This translates to fewer protective device trips, reduced downstream damage, and measurable downtime reductions for machine tools, drives, and control electronics. The SPD is well suited for panel boards, motor starters, and distributed control architectures in manufacturing plants. The 120/240 V split-phase rating and multi-port operating voltages support standard industrial power topologies. Compatible with common control enclosures, it enables seamless integration with existing wireways and busbar arrangements, helping engineers meet NEC/IEC requirements while simplifying upgrade paths for aging installations. NEMA 4X stainless steel enclosure with external sidemount provides rugged protection against dust, moisture, and washdown environments. This reduces enclosure maintenance and allows siting in exposed locations such as outdoor panels or damp factory floors; installation remains straightforward thanks to the external mounting design and standardized accessory package. UL 1449 certification and a 15-year warranty offer regulatory reassurance and long-term reliability. The combination of certification and coverage minimizes compliance risk during audits and lowers total cost of ownership by reducing replacement and service costs over the device life. External sidemount configuration and standard feature package speed commissioning, simplify retrofits, and support flexible layouts in evolving facilities. The compact footprint and clear labelling help field technicians connect the right conductors quickly, boosting first-time right installations and improving overall project timelines. Operating voltage options and robust surge protection align with automation trends such as PLC-controlled machines, robotics, and packaging lines, delivering improved uptime and predictable protection for critical loads.

FAQs
SPD100240S2Q is designed for external sidemount installation on 120/240 V control panels and switchgear. Use the included standard feature package and mount on the panel exterior per the mounting method specification. The stainless steel NEMA 4X enclosure provides weather and washdown resistance, while the external mounting keeps wiring tidy and simplifies service access.
A 100 kAIC interrupt rating means the surge protection device can safely absorb high-energy surges without tripping or degrading protection downstream. This translates to longer life for protected devices, fewer nuisance trips, and improved reliability for drives, PLCs, and motor controllers operating in demanding industrial environments.
Yes. The unit employs a NEMA 4X stainless steel enclosure designed for rugged, outdoor, and washdown environments. External sidemount installations extend protection to exposed panels while maintaining accessibility for maintenance. Always verify site conditions and follow Eaton installation instructions to ensure optimal protection in harsh environments.
SPD100240S2Q is UL 1449 listed, confirming adherence to essential surge protection safety standards. This certification supports compliance during audits and supplier quality assessments. The 15-year warranty further enhances reliability and reduces long-term risk for mission-critical automation installations, provided local codes and NEC/IEC guidelines are followed during installation.
The device features a 15-year warranty and low-maintenance design, contributing to a favorable total cost of ownership. By delivering reliable surge protection against transient events, it reduces downtime, minimizes spare-part consumption, and extends the life of protected equipment such as drives and controllers, yielding a measurable return on investment in modern automation environments.
