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, rate operational voltage up to 690V, rate operational current from 1A to 125A, controller setting current from 0.4A to 125A, control motor power from 0.12kW to 55kW. It is capable of making, carrying and breaking currents under normal conditions, including specifie operating overload conditions and of making, carrying for a specifie time and breaking currents under specifie abnormal conditions such as those of short-circuits.
NBK1 series CPS is applie to power distribution and motor protection & control of various occasions or systems, e.g. infrastructure, buildings, communications, etc.
Standard: IEC60947-6-2 Multiple function equipment-Control and protective switching devices (or equipment) (CPS).
