Special features
Basic
250 kA per phase surge rating delivers robust protection against lightning and utility transients, reducing the likelihood of catastrophic equipment damage. This translates to lower maintenance costs and less unplanned downtime in critical lines such as data centers, manufacturing cells, and large commercial panel banks. The single module format simplifies replacement and reduces cabinet space requirements while maintaining high protection margins for 120/240 V split-phase systems. 120/240 V compatibility aligns with standard industrial power architectures, enabling quick integration into existing panels and minimizing rewiring. The NEMA 4X enclosure with an internal terminal block provides reliable outdoor or harsh-environment performance and streamlined wiring, improving installation speed and field reliability. RoHS compliance supports regulatory requirements and sustainable design practices across facilities. A 15-year warranty (20 years with registration) further lowers lifecycle risk and strengthens total cost of ownership.

FAQs
The SPM250240S1X is designed for industrial control panels, commercial buildings, and data centers that require reliable transient protection on 120/240 V split-phase systems. Its NEMA 4X enclosure supports outdoor or harsh environments, while the internal terminal block simplifies wiring and reduces field connections. This combination accelerates installation and minimizes commissioning risk in new builds or retrofits.
The device provides surge protection with a rating of 250 kA per phase, guarding against high-energy transients from lightning or switching events. It is a single-module unit compatible with 120/240 V systems, engineered to interrupt surges before they reach sensitive equipment. This protection reduces component wear, prevents unexpected shutdowns, and supports more predictable maintenance cycles.
Eaton’s SPM250240S1X carries UL 1449 and UL 1283 listings, as well as CSA Std. C22.2 No. 8-M1986 and CSA Electrical Notice No. 516 Edition 1. It is RoHS compliant, supporting environmental and regulatory compliance in many regions. These certifications provide confidence in safety performance, reliability, and suitability for lifecycle-managed installations.
The internal terminal block streamlines wiring, enabling cleaner, shorter conductor runs and fewer field connections. This reduces installation time and the risk of miswiring, improving overall reliability. For panel shops and on-site installers, the integrated terminal block supports quick maintenance or replacement while maintaining a secure, code-compliant connection.
The SPM250240S1X carries a 15-year warranty from the date of delivery, with an extended term of 20 years when registered on Eaton’s site. This warranty, combined with the device’s rugged enclosure and high surge capacity, delivers strong total cost of ownership. End users benefit from reduced downtime, predictable performance, and long-term protection of critical assets.
