Furse ESP M2/M4 Series


Combined Type 1, 2 and 3 tested protector (to BS EN 61643-11) for use on the main distribution board directly feeding electronic equipment such as computers, communication and control equipment, particularly where a structural Lightning Protection System (LPS) is employed.

For use at boundaries up to LPZ 0A to protect against flashover (typically the main distribution board location) through to LPZ 3 to protect sensitive electronic equipment.

Features and Benefits

  Very low let-through voltage between all sets of conductors (phase to neutral, phase to earth and neutral to earth)
  Full mode design capable of handling high energy partial lightning currents as well as allowing continual operation of protected equipment
  Innovative multiple thermal disconnect technology, for safe disconnection from faulty or abnormal supplies (without compromising protective performance)
  Three way visual indication of protection status
  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 base provides ultra low inductance earth bond to metal panels
  Convenient holes for flat mounting

Models

  ESP 415 M2
  ESP 415 M4
  ESP 480 M2
  ESP 480 M4



Application

Use ESP M2 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 M4 versions on main distribution panel for buildings with a Class I or II LPS fitted.

Installation

Install in parallel, within the power distribution board, either on the load side of the incoming isolator, or on the closest outgoing way to the incoming supply.

Connect, with very short connecting leads, to phase(s), neutral and earth. Phase/live connecting leads should be fused with high rupture capacity (HRC) fuses, a switchfuse, MCCB or type 'C' MCB.

Accessories

  Weatherproof enclosures - WBX M2 for use with the ESP XXX M2 and WBX M4 for use with the ESP XXX M4
