Eaton SPM160240S4T Surge Protection Device - UL 1449
Part Number: SPM160240S4T
Quick Summary
Surge protection device shields power distribution panels in industrial facilities from damaging transients. Without reliable protection, outages and equipment damage can drive costly downtime and escalating maintenance costs. UL 1449 listed and a NEMA 4 enclosure with an internal terminal block ensure rugged, code-compliant performance in harsh environments. Designed for 120/240V split-phase systems and the Eaton SPD Max Series, it delivers high surge capacity while simplifying installation and ongoing protection. That combination translates to reduced downtime, longer equipment life, and easier procurement for electrical teams.

High surge current rating: 160kA per phase provides robust transient clamping for 120/240V split-phase systems, reducing risk of damage to motors, drives, and control circuits. Business impact: lower repair costs, minimized downtime, and longer equipment life. Application: ideal for main distribution panels and subpanels in manufacturing lines and data centers. Voltage rating compatibility: 120/240V split-phase supports common facility power architectures, enabling fast integration into existing electrical rooms and new installations without rewiring. Business impact: smoother procurement and faster commissioning. Application: retrofit projects and new builds across industrial environments. Rugged enclosure and wiring: NEMA 4 enclosure with an internal terminal block protects against dust and moisture while simplifying field wiring. Business impact: safer installation, fewer field wiring errors, and reliable operation in harsh environments. Application: outdoor or washdown areas and challenging plant floors. Installation efficiency: Internal terminal block reduces external wiring steps and streamlines wiring diagrams. Business impact: faster MTBF commissioning and reduced labor costs. Application: panel builders and contractors targeting shorter project timelines. Compliance and footprint: UL 1449 certification ensures conformance to surge protection standards; dimensions (9.5 in depth, 17.05 in height, 15 in width) and 52 lb weight support solid mounting in standard enclosures. Business impact: predictable space planning and improved site readiness. Application: facilities needing robust, code-compliant protection in demanding settings.

FAQs
Installers should account for the device's internal terminal block and its 9.5 in depth, 17.05 in height, and 15 in width. Verify a 120/240V split-phase supply, confirm UL 1449 compliance, and ensure mounting within a suitable enclosure rated at least for NEMA 4 environments. Plan wiring routes to minimize interference with adjacent components and label the SPD accordingly.
The unit operates on 120/240V split-phase with a surge current rating of 160kA per phase, providing robust transient clamping for industrial loads. This combination supports protection for motors, drives, and control circuits, reducing the likelihood of nuisance outages and equipment damage during utility or switching transients. UL 1449 listing further confirms compliance with protective standards.
Yes. The SPD Max device features a NEMA 4 enclosure, designed for dust and water resistance, plus an internal terminal block that simplifies field wiring. This makes it appropriate for outdoor installations, washdown areas, and harsh plant environments while maintaining reliable surge protection for critical panels.
The SPM160240S4T is UL 1449 listed, a key certification for surge protection devices. This certification provides assurance of performance under surge conditions and helps meet electrical codes and safety requirements. The combination with a NEMA 4 enclosure also supports compliance with environmental and installation standards in demanding facilities.
ROI is driven by reduced downtime, lower replacement costs for sensitive equipment, and fewer nuisance outages due to transients. The 160kA per phase rating ensures strong protection for 120/240V systems, while UL 1449 and NEMA 4 enclosure minimize compliance risk and maintenance complexity. Overall, facilities can expect improved reliability and longer asset life with minimal ongoing maintenance.
