The Edco SHA-1260 is a 120VAC single-phase 2W+G, 60A surge suppressor/filter designed to shunt electrical type transients affecting the electrical distribution inside a traffic cabinet. The Edco SHA-1260 offers 75kA per mode and 150kA per phase of surge current protection. The Edco SHA-1260 utilizes Thermally-protected Metal Oxide Varistors (TMOVs) with an integrated thermally-activated elemented designed to open in the event of overheating due to the abnormal over-voltage, limited current conditions.
