Mode of operation: The energy required to switch on the CVB is stored by a spring. It takes only a small pulse energy to unlock the main spring release latch and set free the stored energy. As soon as the supply voltage is applied, the spring gets recharged in less than 10 s. When no control voltage is being applied, the vacuum circuit breaker is in switched off position and the spring remains charged and ready for the next switching operation. Features: ƒÜ Electrically driven vacuum circuit breaker ƒÜ No secondary supply energy like pressurized air required ƒÜ Versions for 15 kV and 25 kV to UIC 550 available ƒÜ Maintenance free: 200,000 operating cycles ƒÜ Following the fail safe principle Application: ƒÜ AC main switch in electric locomotives and EMUs Standards: ƒÜ IEC 60077-4, EN 50124-1, IEC 60694, EN 50155, EN 50121-3-2 CVB15, CVB25 Switchgear for Traction AC Vacuum Circuit Breaker Nominal voltage UN 15 kV AC, 16 Hz OV4 / PD4 25 kV AC, 50/60 Hz OV4 / PD4 Rated operating voltage Ue 17.5 kV AC 30 kV AC Rated operating current Ie 750 A 450 A Short circuit breaking capacity 25 kA 20 kA Utilization category C3 Control voltage Ucontrol 24 / 110 V DC* Operating temperature range - 40°C ... + 70°C Ordering code: Example: CVB15-X-110E-00 Series CVB AC vacuum circuit breaker Nominal voltage 15 / 25 15 kV AC, 16 Hz / 25 kV AC, 50/60 Hz BTE terminal X / R / L none / right / left Control voltage 24 / 110* 24 / 110 V DC Tolerance E -30 % … +25 % Aux. contacts, type and number of 00 10x S826 a L, SPDT * others on request
