FZ(R)N25-12D/T type is three-phase ac, rated voltage 12kV, frequency 50Hz indoor high pressure vacuum load switch equipment (short for "load switch"). It is mainly used in medium voltage power distribution system. Under normal circuit conditions, it can break, close and load current. The short-circuit current can be closed under abnormal circuit conditions; It also has the ability to carry short circuit current within the specified time. FZRN25-12d vacuum load switch - fuse combiner (" combiner ") can be used as an overload and short-circuit protection switch for power transformers and electromechanical devices.
Can be widely used in power plants, petrochemical, metallurgy, mining, airports, railways, highways, ports, factories, schools, buildings, hotels, shopping malls, hospitals, property management area, the urban rural infrastructure construction projects. Suitable for installation in ring network switch cabinet, box type substation and other types of switchgear. Because of its strong ability to open and break, it is the ideal product for the construction, transformation and renewal of distribution network, distribution substation and open and closed.
This product is fully compliant with the national standard GB3804, GB16926, GB1985, GB11022 and IEC 60265-1:1998 and IEC 62271-105:2002 standard specification, so it can operate reliably around the world.
