Furse ESP M1R, M2R, M4R Series


Combined Type 1, 2 and 3 tested protector (to BS EN 61643-11) 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.

Remote display allows both display and protector unit to be mounted in their optimum positions. For use at boundaries up to LPZ 0A to protect against flashover (typically the main distribution board location, with multiple metallic services entering) through to LPZ 3 to protect sensitive electronic equipment.

Features and Benefits

  The remote display means the protector can be mounted close to the incoming feed or first way on the distribution board and the display in an easily visible position, e.g. on front of cabinet
  Very low let-through voltage (enhanced protection to BS EN 62305) between all sets of conductors (phase to neutral, phase to earth, neutral to earth - Full Mode protection)
  Full mode design capable of handling partial lightning currents as well as allowing continual operation of protected equipment
  Repeated protection in lightning intense environments
  Innovative multiple thermal disconnect technology for safe disconnection from abnormal or faulty supplies
  Remote display gives three way visual indication of protection status and is easily installed using standard drilling tools
  Plug-in cable connections between protector and display enable easy connection (1m cable supplied as standard)
  Advanced pre-failure warning so you need never be unprotected
  Remote indication facility allows pre-failure warning to be linked to a building management system, buzzer or light
  Changeover active volt free contact enables the protector to be used to warn of phase loss (i.e. power failure, blown fuses, etc)
  Unique flashing warning of potentially fatal neutral to earth supply faults (caused by incorrect earthing, wiring errors or unbalanced conditions)
  Robust steel housing (protector), and sturdy ABS housing (display)
  Base provides ultra-low inductance earth bond to metal panels
  Remote display comes with integral fixings and a panel drilling template



Application

Use ESP M1R versions on main distribution panel for buildings with multiple metallic services (e.g. gas, water, telephone lines) and on sub-distribution boards feeding sensitive equipment.

Use ESP M2R versions on main distribution panel for buildings with a Class III or IV structural LPS fitted or exposed 3 phase power lines where no LPS is fitted. Use ESP M4R versions on main distribution panel for buildings with a Class I or II LPS fitted.

Installation

Installation of the protector unit is identical to the ESP M1, M2 or M4 Series.

Position remote display, making sure that the cable is long enough, is unimpeded within the cabinet, and allows a minimum of 60mm behind the panel front (for the interconnection cable).

Accessories
