SKU: ESP240M1

ESP240M1 - Single Phase Full-Mode Protector

Single Phase, Full Mode 240V 
Furse ESP M1 Series are an 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 over voltages 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.

 

Key Features

  • Combined Type 1, 2 & 3 surge protection
  • Tested to BS EN 61643
  • For 240V mains power distribution systems
  • Designed to protect sensitive electronic equipment
  • Ideal for LPZ 0 to LPZ 3 boundaries
  • Prevents damage from lightning or transient events
  • Suitable for installations with multiple metallic service entries
  • Compact and easy to install

Questions & Answers

To assess the need for surge protection, conduct a risk assessment in accordance with BS EN 62305:2006 Part 2.  Furse provides a bespoke risk assessment software package called StrikeRisk to simplify and speed the process.

Furse® SPDs are designed to protect electrical and electronic systems from transient overvoltages caused by lightning strikes, switching operations or parasitic interference. They limit these overvoltages and divert damaging surge currents away from sensitive equipment.

Furse® recommends installing SPDs at the service entrance of a building (Type 1) and at sub-distribution panels (Type 2) to protect against surges from indirect lightning strikes, electrical switching and other sources. Proper installation is essential to safeguard sensitive electronics throughout the facility.
