FAQs
When installing the SPM250208Y1T in 120/208 V Wye panels, ensure the panel space accommodates the 14.91 inch width, 17.5 inch height, and 9.3 inch depth, and verify mounting within a NEMA 4 rated enclosure. Route conductors through the internal terminal breaker to maintain clean wiring and minimize heat buildup. Always consult the installation sheet for torque specifications and sequence guidance to sustain UL and CSA compliance.
A 250 kA per phase rating provides a high-energy absorption capacity, reducing the likelihood that transient surges will exceed the device’s limits. This translates to lower risk of insulation breakdown, fewer protective device trips, and reduced downtime for hallway feeders, motor drives, and control panels. For critical loads, this margin improves power quality during lightning events or switching transients, especially in harsh industrial environments.
Yes. The SPM250208Y1T features a NEMA 4 enclosure designed for outdoor and dirty environments, protecting internal components from moisture, dust, and corrosion. This makes it a practical choice for exterior panels, substations, and load centers near production floors. Proper installation requires following the enclosure mounting guidelines and ensuring compliant cabling to maintain protection ratings.
The device is UL 1449 and UL 1283 certified, CSA listed ( CSA Electrical Notice NO. 516 Edition 1 and CSA Std. C22.2 No. 8-M1986 ), and RoHS compliant. These certifications confirm safety and performance under industry norms, aiding regulatory approvals, panel approvals, and end-user confidence for electrical protection in industrial settings.
Expect extended equipment life and reduced downtime due to improved transient protection, which lowers maintenance costs over the system’s life. The 15-year warranty (20 years when registered) reduces replacement risk, while RoHS compliance and UL/CSA certifications simplify procurement and compliance overhead. For capital projects, the SPD can justify faster payback by safeguarding critical automation assets and reducing unscheduled outages.
