250 kA per phase surge capability provides a strong protection margin, translating to fewer downstream failures in critical equipment like motors and drives, and minimizing unplanned downtime. This rating directly lowers maintenance costs and improves overall plant reliability, especially in environments with high-energy transients such as lightning strikes or switchgear switching. The device operates on 120/240 V split-phase power, enabling straightforward integration into existing US distribution schemes, reducing wiring complexity and labor time while preserving performance across diverse loads. The NEMA 4X enclosure with an internal terminal block offers rugged, weather-resistant serviceability, simplifying installation and field wiring in damp or outdoor locations. Standard surge counter delivers traceable protection events for easier maintenance planning and regulatory compliance, helping facilities managers meet internal and external audit requirements. RoHS compliance and established UL/CSA certifications further reinforce safety, environmental responsibility, and long-term reliability, supporting procurement and lifecycle planning. With a 15-year warranty (20 years when registered), this SPD MAX device reduces total cost of ownership and extends the life of protected equipment, even in demanding industrial settings. Dimensions and weight—9.3 in length, 14.91 in width, 17.5 in height, 50 lb—provide a clear mounting footprint for installers and OEMs, enabling confident integration into panel layouts and assemblies.

FAQs
Install the SPM250240S3X in the main or branch panel as a single-module surge protector with the internal terminal block making wiring straightforward. Verify line and load connections per the catalog page, ensure adequate clearance for heat dissipation, and follow local electrical codes. The unit’s 9.3 in L x 14.91 in W x 17.5 in H footprint and 50 lb weight influence mounting location and support needs.
Yes. The device features a NEMA 4X enclosure with an internal terminal block, designed for damp or outdoor environments and for easy wiring inside the enclosure. This arrangement reduces external wiring exposure and simplifies commissioning, while maintaining robust protection against dust, water ingress, and corrosion typical of industrial settings.
The unit is UL 1449 and UL 1283 certified and also references CSA Electrical Notice No. 516 Edition 1, with RoHS compliance. These marks verify electrical safety, surge protection performance, and environmental responsibility, helping facilities meet regulatory requirements and pass audits for electrical protection in industrial and commercial applications.
A 250 kA per phase rating provides a generous margin against high-energy surges common in industrial settings, such as lightning or switching transients. This reduces the risk of downstream device damage, extends the life of drives and controllers, and minimizes unexpected downtime, enabling more stable production and lower maintenance costs over time.
The SPD MAX SPM250240S3X carries a 15-year warranty from delivery, with a 20-year option if registered on Eaton’s SPD site. This extended warranty reduces long-term replacement costs and provides greater predictability in budgeting for asset protection, making it a cost-effective choice for both new installations and retrofits.
