FAQs
The SPM300220Y1T is designed for 127/220 V Wye (4W+G) systems, making it a straightforward upgrade for facilities with common three‑phase distributions. Its internal wiring and NEMA 4 enclosure support easy installation in both indoor and outdoor panels, reducing the need for extensive reconfiguration and delivering reliable surge protection for critical loads.
This model carries UL 1449 and UL 1283 certifications and CSA eligibility, along with RoHS compliance. These markings confirm safety, electrical performance, and environmental responsibility, helping you meet regulatory requirements for industrial and commercial installations.
Yes. The unit is housed in a NEMA 4 enclosure with an internal terminal breaker, designed to withstand damp and outdoor environments. This enables installation on exterior walls, in electrical rooms with moisture exposure, or in harsh industrial settings without compromising protection.
A built‑in surge counter provides real‑time visibility into protection performance, aiding preventive maintenance planning. Combined with the device’s robust construction and long warranty, this allows facilities teams to track surge events, validate protection effectiveness, and optimize downtime planning.
The 15‑year warranty (20 years with registration) reduces lifecycle risk and replacement costs, while high surge capacity and reliable protection minimize unplanned outages. In combination with RoHS compliance and recognized standards, this translates to lower maintenance expenditure, improved uptime, and better budgeting for long‑term electrical protection.
