Overview

The Surge Pure M1-1480-4 is a secondary-level surge protective device (SPD) engineered for robust protection in critical industrial and commercial applications. This unit is intended for downline applications and IEEE Category B sub-panels in 3∅ WYE AC service systems with a Nominal AC Line Voltage (VRMS) of 277/480 and 50/60 Hz frequency compatibility. Its strategic deployment contributes to a robust, layered protection grid essential for maintaining long-term AC power system integrity.

In plain terms, the M1-1480-4 functions to isolate sensitive downline equipment from external transient power issues and, critically, from internal surges caused by nearby switching motor loads. It provides multi-element ME* protection in L-N, L-L, and N-G modes. With a high Total Surge Capacity of 240 kA (at 8x20 µsec pulse) and a Max ME* Surge Current Per Mode/ Per ∅ of 40/80 kA, the device utilizes non-degrading SPD technology to effectively divert harmful energy and minimize downtime.

For install fit, the M1-1480-4 is housed in a compact 4½" x 4½" x 2¾" enclosure, which is rated 'NEMA 12' Indoor, Dust, Drip, Light Splashing Proof. The unit is designed for easy mounting and 'close-coupled' surge protection via its 36" #14 AWG Stranded Copper: 4+G leads. Installation requires that Overcurrent Protection be Type 2 only, use 15 amp breaker - CODE RULE 26-420. Protection status is confirmed via the Lifetime Green LED Self Test 'Protection Status Monitors' For Each Phase. Always follow local electrical code and use a qualified electrician where required.

When choosing this model, verify your system is a 3∅ WYE AC service with a Nominal AC Line Voltage (VRMS) of 277/480 and operates at a 50/60 Hz frequency. Key performance metrics to confirm include the UL 1449, 5th Ed VPR Rating of L-N/L-L @ 20kA, In: 1800/2500 and the Max Continuous Operating Voltage (MCOV) of 320/550. The device is c-ETL-us Listed and Certified to the latest UL 1449, 5th Edition / CSA C22.2 - no. 269, ensuring compliance and safety standards, and includes a Manufactures Guarantee - 10 Year Warranty.
