Overview

The Surge Pure M2-1120-3 is a primary-level surge protective device (SPD) engineered for critical industrial and commercial applications. It is specifically intended for installation at service entrances or main distribution panels, creating the first line of defense in a protection grid. The device is designed for 1∅ AC service, operating effectively with nominal AC line voltages of 120/240 VRMS across standard 50/60 Hz frequencies, providing Single Element (SE\*) protection in L-N, L-L, and N-G modes.

In plain terms, the device's function is to isolate sensitive downline equipment from high-energy external utility hazards, including lightning events, as well as significant internal surges. It provides robust defense with a Max SE* Surge Current Per Mode/ Per ∅/kA of 50/100 and a Total Surge Capacity of 165 kA (at 8x20 µsec pulse). Its integral use of non-degrading SPD technology works to ensure long-term, continuous 24/7 AC power system integrity.

For installation planning, the Surge Pure M2-1120-3 is housed in a robust indoor/outdoor (NEMA 4X) enclosure, signifying its resistance to corrosion, dust, drip, and hosedown conditions. The overcurrent protection is rated as Type 1 & Type 2, no breaker required / for fast easy panel installations, use 20 amp breaker - CODE RULE 26-420 (2). Connection is facilitated by 36" #12 AWG Stranded Copper: 3+G leads. Always follow local electrical code and use a qualified electrician where required.

When choosing this model, verify that your system is a 1∅ AC service with a nominal line voltage of 120/240 VRMS and 50/60 Hz frequency. Key performance metrics include a Max Continuous Operating Voltage (MCOV) of 150/320 and a UL 1449, 5th Ed VPR Rating of L-N/L-L @ 20kA, In: 700/1000. Operational status is confirmed via the Lifetime Green LED Self Test 'Protection Status Monitors' For Each Phase, and the device is backed by a Manufactures Guarantee - Lifetime Warranty.
