| High-voltage fuses | AC vacuum circuit breaker | ||||||||||||||||||||||||||||||||||||||||||
| For the protection ofhigh-voltage switchgear Schaltbau offers a comprehensive range of high-voltage fuses and fuse holders. F-HS Series fuses are main fuses disigned for nominal currents of 7.5 A up to 125 A, whereas F-VS Series fuses are distribution fuses designed for nominalcurrents of3Aupto16A. | CVB Series vacuum circuit breakers are used as main switches on electric locomotivesand multiple units.Thereareversionsfor 15 kVand 25 kVin accordance with UIC 550. Mode of operation: As soon as the control voltage is applied, the energy stored in a spring is set free to trigger the switching operation. After that the spring is recharged. Thevacuum circuit breaker is in switched off position when no control voltage is being applied, and the spring remains charged and ready for the next switching operation. | ||||||||||||||||||||||||||||||||||||||||||
