SurgeFree™
MODEL
PT250•PT160•PT120
Service Panel Protection
Taking compact protectors to the next level, MCG's new PT Series is the most advanced nonmodular protector money can buy. Within its small 10" x 10" enclosure, there are up to 20 high energy, thermally protected varistors packed inside. These high performance varistors are typically only found in much higher priced protectors. Critical electronics are saved by multiple fused surge paths per phase. The redundant paths are comprised of high energy surge fuses that conduct large surge currents repeatedly without degrading. Front panel protection status LEDs and 1 Form C relay contacts let you know the protector's status at a glance. A surge even counter (standard on PT250) displays the number of times that the protector diverts a surge. An abnormal voltage monitor LED monitors voltage between Neutral and Ground, illuminating when abnormal voltages are detected. The PT Series guards small to moderately sized service entrance panels as well as branch panels, transfer switches and network closets. SEE SPECIFICATIONS
