IR4000V Series

The IR4000V Series is a range of single pole, air, high speed circuit breakers for DC applications, available in two voltage ratings of 1800 and 3600 Vdc and two thermal currents of 3 and 4.5 kA.

This is the right choice when you need a powerful circuit breaker solution for onboard applications in Metro, Light train, EMU, High speed train, and locomotive rolling stock (IEC 60077).

  • Operational Frequency class : C3
  • Designed for applications up to OV4, PD3A
  • Current interruption direction: bi-directional DC
  • Direct acting over-current trip device: indipendant bi-directional
  • DC coil controlled with Electronic power saving system
  • Offerd in 8 versions to let you choose the best solution, and fit any requirements with a catalogue product.
  • Ceramic fins combined with arcing contacts technology ensure highest breaking and endurance performances.
  • Electrical arc safely contained inside the arc chute, reduced insulation distances towards external metallic parts.
  • The extended working range of power supply exceeds the limits prescribed by the standards with no external DC/DC converter.
  • Motor-operated closing to require the lowest closing power consumption.
  • Standard Current driving & holding system performed with an electronic board in order to get mechanical and tripping performances regardless of power supply voltage and temperature fluctuations.
  • Reed-type auxiliary contact technology to achieve the most reliable feedback signal thanks to the vacuum protection against dust, pollution and oxidation.
  • TSI Recognized
