The ABB Furse ESP 415 M4 is a combined type one, two and three surge protective device housed in steel with a very high surge current rating.


  • Extra high maximum surge current of 120kA (480kA unit total)
  • Very low let-through voltage between all sets of conductors (phase to neutral, phase to earth and neutral to earth).
  • Repeated protection in lightning-intense environments, with 20 year predicted lifetime.
  • Innovative Sovtrip multiple thermal disconnect technology anticipates standards authorities’ future demands 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.
  • A 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.
  • The protector base provides ultra-low inductance earth bonds to metal panels.
  • Convenient holes for flat mounting.
  • Compact size for installation in the power distribution board.
  • Maintenance free
