With a 160 kA per phase surge rating, this device clamps high-energy transients before they reach connected loads, reducing the risk of nuisance trips and equipment damage. The immediate business impact is fewer downtime events and lower replacement costs for sensitive drives and controllers. In practice, technicians install it at the main service or feeder panels to protect line-side equipment on manufacturing lines and critical process controls. Designed for 230 V single-phase systems, it integrates cleanly into common distribution architectures, enabling reliable performance without panel reconfiguration and supporting fast commissioning in new builds or retrofits for data centers, packaging lines, and plant-floor instrumentation. Its NEMA 4 enclosure combined with an internal circuit breaker simplifies mounting and maintenance while delivering weather resistance in indoor/outdoor installations; it reduces wiring complexity and ensures clear fault isolation in washdown environments and harsh factory floors. As part of Eaton's SPD MAX series, the SPM160230L4R benefits from proven surge protection technology and seamless compatibility with Power Xpert SPD networks, supporting centralized monitoring and easy replacement within protection schemes. Weighing 52 lb with 15 in width, 17.05 in height and 9.5 in depth, the unit is built for robust electrical spaces and long service life, with UL 1449 certification underlining performance and safety for industrial projects.

FAQs
The SPM160230L4R is designed for single-phase 230 V circuits and fits common Eaton Power Xpert panel styles. Installation follows the included wiring diagram, with field-installable connections and an internal circuit breaker simplifying protection routing. Ensure proper clearances, ground connections, and adherence to local electrical codes for a safe, compliant retrofit or new-install.
SPM160230L4R provides 160 kA per phase surge current at 230 V, UL 1449 listed for certified performance, and a robust NEMA 4 enclosure. In practice, it clamps transients effectively to protect downstream equipment, reducing nuisance trips and extending the life of drives, PLCs, and controllers in manufacturing floors, data centers, and process lines.
Yes. The unit uses a NEMA 4 enclosure designed to resist dust, water ingress, and corrosion in harsh environments. For outdoor or washdown areas, ensure proper mounting with sealing and local climate considerations. Its internal circuit breaker also helps isolate faults quickly, minimizing panel disruption in challenging facilities.
SPM160230L4R is UL 1449 listed, signaling conformance to established surge protection standards. This certification supports compliance programs for machinery and panel builders, providing a verifiable protection baseline. While CE or IP specifics aren’t listed in the datasheet, engineers should verify regional requirements and confirm compatibility with their jurisdictional electrical codes.
Using the SPM160230L4R reduces unplanned downtime and the frequency of component replacements by stabilizing voltage transients that damage drives and sensors. Although initial cost is higher than basic protectors, the long-term ROI comes from fewer outages, lower maintenance labor, and easier replacement within Eaton’s Power Xpert SPD ecosystem.
