Overview
The Surge Pure M2-1208-4 is an industrial-grade, primary-level surge protective device (SPD) suitable for both Type 1 and Type 2 installation locations. This unit is specifically engineered for 3∅ WYE AC electrical systems with a nominal AC line voltage of 120/208 VRMS, supporting standard 50/60 Hz frequencies. Providing robust Single Element SE\* protection across L-N, L-L, and N-G modes, this device is intended for service entrances or main distribution panels to establish the foundational layer of a comprehensive protection grid.
In plain terms, the M2-1208-4 functions as a robust defense mechanism to isolate critical, sensitive equipment from high-energy external utility hazards, lightning hazards, and damaging internal surges. With a maximum SE* Surge Current Per Mode/Per ∅ of 50/145 kA and a substantial Total Surge Capacity of 355 kA (at 8x20 µsec pulse), the device delivers significant, non-degrading surge capacity. The Maximum Continuous Operating Voltage (MCOV) is rated at 150/320 V, with UL 1449, 5th Ed VPR ratings of 700/1000 V for L-N/L-L @ 20kA.
For installation planning, the component is housed within a durable, NEMA 4X rated enclosure, making it suitable for both indoor and outdoor environments with protection against dust, drip, hosedown, and corrosion. The Overcurrent Protection is certified as Type 1 & Type 2, no breaker required / for fast easy panel installations, use 20 amp breaker - CODE RULE 26-420 (2). This facilitates straightforward mounting and 'close-coupled' surge protection via its 36" #12 AWG Stranded Copper: 4+G leads. Always follow local electrical code and use a qualified electrician where required.
When choosing this model, verify that your system is a 3∅ WYE AC service with a nominal line voltage of 120/208 VRMS and a 50/60 Hz frequency. Key safety and performance metrics include the Certifications: c-ETL-us Listed and Certified to the latest UL 1449, 5th Edition / CSA C22.2 - no. 269, RoHs Compliant. Furthermore, the unit provides continuous operational feedback via Lifetime Green LED Self Test 'Protection Status Monitors' For Each Phase, and is backed by a Manufactures Guarantee - Lifetime Warranty.
