Überspannungsableiter

The Enerdoor surge arrester series has been specifically designed to offer surge protection for electrical equipment. Surge arresters are installed at the front end of a system for the purpose of diverting harmful overvoltage transients caused by external (lightning) and/or internal (switching) events to ground safely. Also known as Surge Protection Device (SPD), or Transient Voltage Surge Suppressor (TVSS), Enerdoor surge arrestors protect against electrical transients resulting from lightning strikes that find their way onto electrical conductors. All models include remote contact, visual indicator, and comply with the UL 1449, IEC 61643-11, and VDE 0675 International Standards. DIN rail or screw mounting options are available with select models offering plug and play replaceable cards for quick and easy installation and replacement.
