High interrupt rating delivers superior transient protection, directly reducing equipment damage and maintenance costs while enabling consistent production throughput in harsh industrial environments. This translates to reduced downtime and longer service life for motors, drives, and controls in data centers, manufacturing lines, and panel boards. The 127/220 V Wye (4W+G) configuration ensures compatibility with common 3‑phase systems, simplifying retrofits and new installations without rewiring. A NEMA 1 enclosure with internal disconnect enhances safety during servicing, limiting exposure to live circuits and supporting compliance with workplace electrical standards. The external side mounting option speeds installation and minimizes panel disruption, offering a clean, retrofit-friendly path for upgrades in existing buildings. The 15‑year warranty and standard feature package lower total cost of ownership by reducing replacement cycles and support requirements, while maintaining reliable protection against voltage spikes.

FAQs
Installation is designed for external side mounting on distribution gear. Ensure clearance for cooling, secure mounting with standard hardware, and route wiring per the included wiring diagram. The unit features an internal disconnect for safe servicing and a compact footprint that minimizes panel disruption during retrofit or new install.
100 kAIC indicates the maximum short-circuit current the surge protection device can safely interrupt without sustaining damage. This rating provides robust protection for downstream equipment during high-energy transients, reducing the risk of equipment failure and improving system uptime in demanding industrial environments.
Yes. The SPD100220Y2M is designed for 127/220 V Wye (4W+G) configurations, making it suitable for common three‑phase feeders with a four‑wire grounding scheme. This compatibility simplifies integration with standard industrial electrical distributions and minimizes rewiring work during upgrades.
The device carries UL 1449 certification, confirming compliance with established surge protection standards. It is housed in a NEMA 1 enclosure and is designed for safe operation with an internal disconnect, supporting compliant installation in typical industrial and commercial environments.
ROI comes from reduced unplanned downtime, protection of critical motors and drives, and extended asset life. With a 100 kAIC rating and durable NEMA 1 construction, you can expect fewer surge-related failures, lower maintenance costs, and longer replacement cycles, contributing to lower total cost of ownership over the system’s life.
