Surge Arrester / Protection

Surge voltages are short, pulse-like voltage peaks also known as transients.  Lightening strikes are the most well known cause of extreme surge voltage pulses.  Electricial equipment is continually stressed by transients that occur in the power supply network, such as those caused by switcing operations.  

The Enerdoor surge protection series was 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) or internal (switching) events to ground safely.

Also known as Surge Protection Devices (SPD), or Transient Voltage Surge Suppressors (TVSS), Enerdoor surge arrestors protect against electrical transients that find their way onto electrical conductors.

All models in this series include remote contact and visual indicators, and comply with the UL 1449, IEC 61643-11, and VDE 0675 International Standards.

DIN rail and screw mounting options are available with select models additionally offering plug and play replaceable cards for quick and easy installation and replacement.
