New from Softstart UK is a range of vacuum circuit breakers offering excellent performance, simple maintenance and extended life expectancy. The highly compact Hyundai HAF and HVF vacuum circuit breakers deliver reliable operation over greatly extended service lifespans, with the additional benefit that the low vibration design is extremely quiet.
>Rugged in construction with the minimum number of moving parts, the Hyundai HAF & HVF Vacuum Circuit Breaker operating mechanism features reduced maintenance requirements, providing a long life expectancy of 30,000 operations. Because of the small amount of contact erosion, contact life is increased to 20,000 operations for the rated nominal current.
>Any required maintenance can be easily carried out in-house, and servicing time is extremely short, which keeps downtime to an absolute minimum.
>The enclosed HVF circuit breakers are rated for voltages from 4.76kV up to 40.5kv, with withstand voltages up to 190kV and rated currents up to 4000A. The open frame HAF circuit breakers are rated for voltages from 4.76kV up to 24kV, with withstand voltages to 125kV and rated currents up to 3150A.
