VS1 series embedded pole vacuum circuit breakers are applicable to 24kV, three-phase AC 50Hz indoor switchgear components and can serve as protection and control units for industrial and mining establishments and power transformer substation equipments. With modular and independent-frame design for their spring operating
mechanisms, VMG circuit breakers can operate with KYN28-24 mid-set and fixed switchgear cabinets. These circuit breakers are subject to both fixed installation and assembly with chassis as a handcart unit.
