7.2kv Vacuum Contactor Switch Vacuum Contactor-Fuse Combination (HCR-7.2J(D)Y/D315-50T)

HCR-7.2J(D)Y/D315-50T and HCR-12J(D)Y/D200-50T are applicable on AC 50-60Hz power systems, rated voltage 7.2kV and 12kV, rated current 315A, 200A. It can be installed in the switch cabinet to form an F-C circuit and used in conjunction with a comprehensive protector. The Vacuum Contactor Unit combines a high-voltage fuse capable of breaking a wide range of short-circuit fault currents with a vacuum contactor that can be frequently operated. It can be used for frequent starting of motors and frequent switching of transformers and capacitors. Vacuum Contactor-Fuse Combination is widely used in power systems such as power plants, chemicals, coal mines, metallurgy, ports and wharfs. It can be used by power plants and industrial and mining enterprises to switch on and off AC high-voltage motors, transformers, induction furnaces and other loads, and has the function of short-circuit protection. The trolley at the bottom of the Vacuum Contactor-Fuse Combination can be easily moved out of the control cabinet. The altitude of the environment where the product is used does not exceed 1000 meters above sea level. Technical Data:NameUnitValueMain circuitRated working voltage (Ue)kV7.212Rated working current (Ie)(Depends on the fuse)A≤315≤200Rated frequency (fr)Hz50~60Rated expected short-circuit breaking current (effective value)kA≤50Rated expected short-circuit making current (peak value)kA125Power frequency withstand voltageWiring terminal to earthkV3242Vacuum breakskV3242Lightening impulse withstand voltagekV6075Control circuitRated voltage (Us)VAC 110/220/380DC 110/220Rated power (Ps)electric holdingVA≤1000/100 (absorbing/holding)Rated power (Ps) mechanical holdingVA≤900/600 (Closing/opening)Auxiliary circuitForm (6a+6b)Rated value AC 380V/5AControl circuit, auxiliary circuit to earth power frequency withstand voltagekV2Rated operating frequencyLong-termtime/h300Short-termtime/h600Mechanical endurance10000 times30Electrical endurance10000 times10(AC-3)Mechanical characteristicsClosing timems≤1503-phase asynchronous timems≤3Original opening timems≤150(electric holding), ≤60(mechanical holding)Closing trippingms≤4Remark: 1. rated control voltage can be made according to customer's requirements.2.
