Seitenmontage Typ Innen Hochspannung Vakuum-circ

Summary: VS1-12 series side mounting type indoor high-voltage vacuum circuit breaker is indoor high voltage switchgear, suitable to rated voltage is 12kV, frequency is 50Hz of three-phase power system, as protection and control electric appliances, due to the special vacuum circuit breaker superiority, especially suitable to the rated current needs frequent operation, or multiple open circuit of short-circuit current location. VS1-12 series lateral mounting type vacuum circuit breaker uses stationary installation, mainly used for stationary switchgear, this circuit breaker not only can be used alone, but also can be used for ring net power supply, box variable or various non-standard power supply system.
