Gerapid

 

Gerapid high speed DC circuit breakers are single-pole circuit breakers designed for use in high energy, high reliability DC power distribution systems. They are suitable for protection of mains and semiconductors (converters/rectifiers) in railway and industrial applications.
 
Feeder circuit breakers and rectifier circuit breakers are available with operating currents up to 8,000ADC and operating voltages up to 3600VDC. They have a very high interruption capacity combined with a current limiting characteristic.
