The ABB Furse ESP 415 M4R includes a remote display. The protector can be connected via one of the distribution board’s outgoing fuseways or circuit breakers—ideally, to the outgoing way nearest the incoming supply (or isolator). Suitable for hard-to-access areas or inside enclosures where the remote display can be visible elsewhere or outside a cabinet.

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 years 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 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
