The IR3000F Series is a range of single pole, air, high speed circuit breakers for DC applications with air breaking, available in two voltage ratings of 900 and 1800 Vdc and two thermal currents of 1,5 and 3 kA.

This is the right choice where a very compact and strong solution is required for Fixed Applications, in both railway and industry sector (IEC 61992 and IEC60947) .

• Same breaker with two different holding systems: Holding coil or Permanent magnet in order to get a monostable or bistable device.
• Current interruption direction: bi-directional DC
• Direct acting over-current trip device: uni-directional or indipendant bi-directional
• DC coil controlled with Electronic power saving system

• Offered in 6 sizes to let you choose the smallest dimensions, 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.
  • Motor-operated closing to require low closing power consumption.
  • Standard Current driving & holding system performed with an electronic board to get mechanical and tripping performances regardless of power supply voltage and temperature fluctuations.
• The reed-type auxiliary contacts technology achieves the most reliable feedback signal thanks to the vacuum protection against dust, pollution and oxidation.
