Special features
Basic
Two-module design delivers up to 400 kA per phase protection, shielding critical loads from high-energy transients that can corrupt PLCs, drives, and control electronics. This translates to fewer unplanned outages, reduced maintenance costs, and longer equipment life. In practice, panel builders prefer this arrangement because it localizes protection at the source, simplifying diagnostics and replacements during outages. The device supports 120/208 V Wye configurations, providing universal compatibility for North American facilities and minimizing rewiring when upgrading existing panels. The NEMA 4X enclosure with internal terminal block offers rugged, weatherproof protection suitable for indoor and outdoor or harsh environments, reducing enclosure-related failure risks. RoHS compliance and multiple certifications (UL, CSA) ensure regulatory alignment and risk mitigation in manufacturing and data-center environments. The warranty framework—15 years standard, 20 years with registration—translates into lower lifecycle risk, predictable budgeting, and improved total cost of ownership. Installation benefits include straightforward wiring, compact footprint (9.3 in depth, 14.91 in width), and a robust design that supports rapid field servicing and modular maintenance.

FAQs
Designed for 120/208 V Wye systems, the SPM400208Y1Y installs in standard industrial panels using a NEMA 4X enclosure with an internal terminal block. With two surge modules, it adapts to multi-line protection while keeping wiring organized through the integrated terminal interfaces. The compact depth of 9.3 in and width of about 14.91 in simplify mounting in crowded panels or downstream distribution boards.
The device delivers up to 400 kA per phase protection via its two protection modules, shielding critical loads from energy transients. It is well suited for PLCs, drives, motor starters, and sensitive control electronics in manufacturing lines, data centers, and other industrial facilities. The 120/208 V Wye rating supports common North American power layouts, streamlining integration.
The SPM400208Y1Y is RoHS compliant and UL/CSA listed, including UL 1449 protection, plus additional certifications such as UL 1283 and CSA standards referenced in the product documentation. This certification suite provides regulatory assurance for use in conventional industrial environments and helps satisfy corporate and site-specific compliance requirements.
The unit carries a 15-year warranty from delivery, with an extended 20-year warranty available when registered. This extended coverage reduces replacement risk and supports predictable budgeting. Coupled with reliable surge protection, the SPM400208Y1Y lowers downtime and maintenance costs, contributing to a lower total cost of ownership over the equipment life cycle.
Yes. The internal terminal block and compact footprint simplify wiring and mounting in existing panels, while the NEMA 4X enclosure supports indoor and outdoor use in challenging environments. It is compatible with typical 120/208V distributions and aligns with standard protection schemes, reducing wiring changes and making field servicing straightforward when protection module replacements are needed.
