Special features
Standard with surge counter
Two-module configuration delivers up to 320 kA per phase, providing high-energy surge absorption for demanding industrial loads. This arrangement reduces the likelihood of OEM equipment tripping on small transients and enables downstream devices to operate with stable voltages. Ideal for 240 Delta (3W+G) distributions, it supports scalable protection as your panel counts grow. The NEMA 4 enclosure with an internal circuit breaker enhances rugged reliability in harsh environments, allowing outdoor or washdown areas to stay protected without compromising safety or access for maintenance. A standard surge counter enables proactive monitoring of events, simplifying maintenance planning and improving asset management across the plant. RoHS compliance and certified performance freshen procurement criteria, while the Max series architecture ensures compatibility with existing Eaton protection schemes and future upgrades. The warranty extends for up to 15 years from delivery, 20 years with registration, delivering predictable total cost of ownership and strong ROI for capital-intensive automation projects. Compatibility with the 240 Delta (3W+G) configuration supports scalable protection across multi-panel installations and reduces integration risk for new line builds or retrofits.

FAQs
To install the SPM320240D3S, ensure sufficient panel space for the two-module configuration and related wiring in a three-phase, 240 V Delta system. The unit measures 9.3 in (depth) by 17.5 in (height) by 14.91 in (width) and weighs 50 lb, with a NEMA 4 enclosure and internal circuit breaker for rugged environments. Confirm RoHS compliance and secure against moisture ingress while coordinating with existing Max series protection devices for seamless integration.
The 320 kA per phase rating provides a high-energy absorption capacity, allowing the SPD MAX to clamp severe transients without compromising downstream equipment. In practice, this reduces nuisance trips and voltage excursions on motor drives and contactors, improving reliability in demanding applications such as CNC machines, pumping stations, and automated lines where large transients are common.
Yes. The SPM320240D3S uses a NEMA 4 enclosure with an internal circuit breaker designed for harsh or wet environments, including outdoor installations or damp plant areas. Its RoHS compliance and robust construction support reliable protection across industrial sites, while providing straightforward integration into existing protection schemes for expanded or retrofit projects.
The device is UL 1449 listed and CSA certified (Electrical Notice No. 516; CSA Std. C22.2 No. 8-M1986) with additional UL 1283 endorsement and RoHS compliance. This combination supports procurement in regulated environments and simplifies approval processes for electrical protection equipment across diverse facilities.
The SPM320240D3S carries a 15-year warranty from delivery, extendable to 20 years with online registration, reducing long-term ownership risk. Features such as an integrated surge counter enable ongoing monitoring of protection performance, helping plan preventive maintenance and quantify uptime improvement and asset protection benefits for a favorable ROI in capital-intensive automation projects.
