CHINT NKB1 Control & Protective Switching Device,
NKB1 series control & protective switching device (CPS) is mainly applie to circuit with AC current frequency of 50 Hz or 60Hz,
furthermore rate operational voltage up to 690V, rate operational current from 1A to 125A, controller setting current from 0.4A to 125A,
in addition to control motor power from 0.12kW to 55kW. It is capable of making,
likewisecarrying and breaking currents under normal conditions, including specifie operating overload conditions and of making,
similarly carrying for a specifie time and breaking currents under specified abnormal conditions such as those of short-circuits.
meanwhile NBK1 series CPS is applie to power distribution and motor protection & control of various occasions or systems,
e.g. infrastructure, buildings, communications, etc.
finally Standard: IEC60947-6-2 Multiple function equipment-Control and protective switching devices (or equipment) (CPS).
