อุปกรณ์ป้องกันไฟกระชาก SPD ยี่ห้อ FURSE (ABB)

ESP 120M1 

TYPE 1 2 3 POWER SPD FOR 120V SINGLE PHASE SUPPLIES

Combined Type 1, 2 and 3 tested protector (to BS EN 61643) for use on mains power distribution systems primarily to protect connected electronic equipment from transient overvoltages on the mains supply, e.g. computer, communications or control equipment. For use at boundaries up to LPZ 0 to protect against flashover (typically the main distribution board location, with multiple metallic services entering) through to LPZ 3 to protect sensitive electronic equipment.
