Circuit BreakerNXB-63 1P type C LINKNXB-63 2P type C LINKNXB-63 3P type C LINKNXB-63 4P type C LINK1. Compliant standardsIEC60898-12. Major functionOverload protection, short circuit protection, positive isolation3. Technical parametersRated current: 1A, 2A, 3A, 4A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A; Rated voltage: 230V (1P, 1P+N), 230/400V (2 ~ 4P, 3P+N); Frequency: 50; Electromagnetic release type: C Number of poles: 1P, 1P+N, 2P, 3P, 3P+N, 4P; Mechanical life: 20000 cycles; Electrical life: 10000 cycles; Rated short-circuit breaking capacity(Icn): 6000A; Short-circuit breaking capacity (Ics): 6000A; Rated impulse withstand voltage (Uimp): 4kV; Power consumption on each pole of the circuit breaker: see Table 1.Table 1Rated current In (A) Maximum power consumption per pole (W)1~10 316 3.520~25 432 640 7.550 963 134. Dimensions and installation sizesStrong adaptability to environment and reliable operation in harsh environment-30~70 ambient temperature range, to meet the needs of various applicationsContact indicator window, clear positionAll models of contact head position visualization, avoid wrong operation, use more reliableCircuit breaker and leakage protection choose1.The main switches of the household distribution box is usually a 32A-63A mini circuit breaker or leakage protection circuit breaker which can disconnect the phase line and neutral line at the same time 2.10A-16A miniature circuit breaker is generally selected for lighting circuit 3.Socket circuit generally selects 16A-20A leakage protection circuit breakerswitches current is selected according to equipment power1.Calculation formula = power/voltage *3 (impact current) 2.For example: 3000W equipment 380V voltage select circuit breaker, 3000W*3 (impulse current) /380V 23.68A 25A, we choose 25A circuit breake
