FAQs
SPD100220Y4M is designed for a NEMA 1 enclosure with internal disconnect, simplifying service access and isolation during maintenance. It measures 3.48 in depth by 7.47 in width and 12.05 in height, with an approximate weight of 6.8 lb, making it suitable for standard electrical cabinets. Plan for typical clearance to allow wiring and heat dissipation, and verify compatibility with 127/220 V Wye systems.
The device provides 100 kA per phase surge current rating and operates on a 127/220 V Wye (4W+G) configuration. It carries UL 1449 certification for surge protection devices, and is designed to be installed in industrial environments with Power Xpert SPD compatibility, ensuring reliable protection for critical loads such as panels and drives.
Yes. With 100 kA per phase protection and a 127/220 V Wye rating, the SPD is appropriate for data centers, manufacturing lines, and machine tool panels. The NEMA 1 enclosure and internal disconnect support safe, straightforward installation in commercial facilities, while UL 1449 certification provides assurance of safety and performance in mission-critical environments.
UL 1449 certification is the primary credential for this surge protection device, confirming safety and performance under surge conditions. While other standards such as CE or IP ratings are common in many markets, this model emphasizes UL compliance for robust industrial protection. Certification supports regulatory alignment, reduces risk during audits, and enhances supplier credibility in automation projects.
By limiting transient overvoltages to 100 kA per phase, the SPD helps prevent damage to downstream components, reducing repair costs and downtime. The internal disconnect simplifies maintenance cycles, while UL 1449 compliance minimizes compliance-related risk. Over time, these factors contribute to longer device lifespans for panels and drives and lower total cost of ownership in automation facilities.
