FAQs
The SPM400220Y3S is designed for 127/220 V Wye (4W+G) configurations, enabling straightforward integration with common 4-wire distributions in industrial facilities. Its two-module construction provides robust protection per phase, minimizing compatibility concerns across motors, drives, and PLC-controlled equipment. For new installations or retrofits, confirm existing neutral and grounding arrangements align with the 4W+G topology to maximize protection coverage.
This surge protection device offers 400 kA per phase protection across two modules, delivering substantial energy absorption for transient events. Coupled with a RoHS-compliant design and UL 1449/UL 1283 certifications, it provides reliable performance under fluctuating grid and switching surges. The internal surge counter also helps verify ongoing protection effectiveness during maintenance cycles.
Key certifications include UL 1449 and UL 1283, CSA Electrical Notice No. 516 Edition 1, and CSA Std. C22.2 No. 8-M1986, with RoHS compliance. These indicate electrical safety, EMC conformity, and restricted hazardous substances alignment. Such certifications support compliance reporting, supplier qualification, and procurement decisions in regulated industries.
The built-in surge counter provides verifiable event data, enabling proactive maintenance planning and uptime analytics. Coupled with a 15-year warranty (20 years with registration), the solution lowers total cost of ownership by reducing unplanned outages, extending downstream equipment life, and simplifying asset management. This combination supports faster ROI through measurable reliability improvements.
The SPM400220Y3S features a 9.3 in length, 17.5 in height, 14.91 in width footprint and weighs 50 lb, with a NEMA 4 enclosure and internal circuit breaker. It mounts in standard electrical assemblies and is compatible with the SPM Max series. For best results, plan for outdoor or harsh-environment placement and ensure proper clearance for servicing the surge counter and internal components.
