Surge Protection

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

Surge protection is important because surge voltages cause device destruction, system downtime or total failures, data loss and production downtime.  

The comprehensive Enerdoor surge protection series was designed specifically 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 offering plug and play replaceable cards for quick and easy installation and replacement.
