Miniature Circuit Breaker 6ka 63A CE Knb2-63 S2 4p

Product Description        KNB2-63 series Miniature Circuit Breaker is nice in appearance, reasonable in structure, sound in feature and high in breaking capacity. Installed with standard din rail, it is convenient and easy in usage. It is mainly used in the line of AC 50/60Hz, rated working voltage to 240V/415V, and rated current to 63A as protection against overload and short-circuit. It can be used as infrequent on-and-off operation and changeover.         It complies with standard of GB10963 and IEC/EN60898.    Standard  IEC/EN 60898-1 IEC/EN 60947-2 Electrical featuresRated current In A        1, 2, 3, 4, 6, 10, 13, 16, 20, 25, 32, 40, 50,63 Poles  1P, 1P+N, 2P, 3P, 3P+N, 4P 1P, 2P, 3P, 4P Rated voltage Ue V                                230/400~240/415Insulation voltage Ui V500Rated frequency  50/60HzRated breaking capacity A1000010000Energy limiting class  3 Rated impulse withstand voltage(1.2/50) Uimp V4000Dielectric test voltage at ind. Freq. for 1 min KV21.890Pollution degree  2Power loss per pole Rated current (A)  Max power loss per pole (W)  1, 2, 3, 4, 6, 10 2 16, 20, 25, 32 3.5 40, 50, 63 5Thermo-magnetic release characteristic  B, C, D (8-12)In Mechanical featuresElectrical life  4000Mechanical lif  20000Contact position indicator  YESProtection degree  IP20Reference temperature for setting of thermal element ºC 30Ambient temperature (withdaily average≤35ºC) ºC -5...+40Storage temperation ºC -25...+70InstallationTerminal connection type  Cable/U-type busbar/Pin-type busbarTerminal size top/bottom for  cablemm2 25AWG 18-4Terminal size top/bottom for  busbarmm2 10AWG18-8Tightening torqueN·m2.5In-Ibs.22Mounting On DIN rail EN 60715 (35mm) by means of fast clip deviceConnection From top and bottomCombination with accessoriesAuxiliary contact YESShunt release YESUnder voltage release YESAlarm contant YES  Selectivity  Load side: K    NB1-63, KNB1-63HCurve B, CIn (A)Power supply side: RT36-00 (fuse)202536506380100125160Is (kA)≤21.24>12>12>12>12>12>12>1230.71.23.85.36666640.60.92.53.86666660.50.81.92.54.5566610 0.71.42.23.23.666616  1.21.82.635.66620   1.52.22.54.66625   1.322.24.15.5632    1.71.93.84.5640     1.734550     1.52.63.54.563      2.43.34.5  Load side: KNB1-63, KNB1-63HCurve B, CIn (A)Power supply side: NM8-100S/H/R1620253240506380100Is (kA)≤100.190.190.30.40.50.50.50.630.816  0.30.40.50.50.50.630.820    0.50.50.50.630.825     0.50.50.630.832      0.50.630.840       0.630.850        0.863         Backup protection  Load side:K NB1-63, KNB1-63HCurve B, CIn (A)Power supply side: RT16 series40506380100125160Is (kA)1~6404040404040408~104040404040404013404040403535351640404040303030204040404030303025404040403030303240404040303030404040404030303050303030303030306320202020151515  Load side: KNB1-63, KNB1-63HCurve B, CIn (A)Power supply side: NM8NM8-125SNM8-125HNM8-125RNM8-250SNM8-250HNM8-250RIs (kA)1~615181815151510~2012151512121232~4012151512121250~60121515121212  Temperature deratingThe maximum permissible current in a circuit breaker depends on the ambient temperature where the circuit breaker is placed. Ambient temperature is the temperature inside the enclosure or switchboard in which the circuit breakers are installed.

You must then assign the rating (already derated if necessary according to ambient temperatuer) a downrating factor of 0.8. Shipping:1. Normally by SEA From NINGBO/SHANGHAI TO .Worldwide.. 2.
