Air break
switch for railways
RABS series of air break switches were especially developed for railway, light rail and tram applications. The models range for railways includes 1 pole, 1+1 pole and 2 poles versions for DC 750 – 3500 V, 16.7 and 50 Hz in a range from 15 to 25 kV. The tram DC version is made with 1 pole. The mechanical parts are made of the highest-grade stainless steel, qualified hot dip galvanizing and nickel-plated high-grade copper to prevent from corrosion. Together with our existing motor operators it provides a complete solution for automation and remote control of the railway and tram electrical networks.
- High quality mechanical parts
- Low life cycle cost
- High level of insulation
- Innovative design
- Silicone insulators
- Easy to remote control
