IR4000V Series - On Board Application


The IR4000V Series is the right choice where a very powerful solution is required on on-board application for Metro, Light train, EMU, High speed Train and locomotive rolling stock.

The IR4000V new design combines the highest breaking capability required from the Fixed Application (railways and industry) with the typical requirement from the on-board application as compactness, lightness and capability to withstand Shocks and Vibrations.

The IR4000V Series is a range of single pole, air, high speed circuit breakers for DC applications with air breaking, available in two voltage ratings of 1800 and 3600 Vdc and two thermal currents of 3 and 4,5 kA.

IR4000V Series includes:

  • IR4000VV, Vertical mounting, mostly used for locomotive
  • IR4000VH, Horizontal mounting, mostly used inside a box for roof or underframe mounting
