MCB Moulded Circuit breaker 11kv 630a vacuum circuit breaker

Specifications The breaker is premitted to use the CCC marking of CQC and CE marking issued by TUV Rhineland of Germany.

  Product Description Application ----------------------------------------------------- YEM1L series MCCB with residual current protection(hereafter simply referred to as breakers) are one fof the new type breakers which have been developed by the company using advanced CAD/CAM/CAE design and manufacturing technology.The rated insulation voltage of the breaker is 800V,suitable for turn-on or turn-off not frequency and starting a motor not frequency in the circuit of AC 50Hz,rated working voltage 400V and rated current up to 630A.The breakers have overload,short-circuit and undervoltage protection devices,so as to protect the circuit and the power equipment against damage,Synchronously,the breakers provide indirect contact protection for man,and protect the fire damage may caused by long-term existed earth fault,which can't be examined by the over-current protection device.Additionally,when other protective devices fall to function,YEM1L breakers with the rated residual operating current of 30mA can protect man from the direct contact.The breaker of VA type residual current release can provide in direct contact protection in case of  an earth fault comprising a d,c,component.   According to the rated ultimate short-circuit breaking capacity(lcu),the breakers are classified into two kinds of types:M(second high breaking type),H(High breaking type).The breakers are of the following characterstics:compact size,high breaking capacity,short arc-over distance and shake proof,etc.   The breakers could be installed vertically(upright) or horizontally(transverse).   The breakers can't be fed inversely,only allowing 1,3,5 connect with power supply wires,2,4,6 connect with load wires.   The breakers comply with the demands of the following standards:     IEC60947-1and GB14048.1-2006 General rules     IEC60947-2and GB14048.2-2008 circuit breakers and annex B circuit-breakers incorporating residual current protection     IEC60947-4-1 and GB14048.4 Electrome-chanical contactors and motor starters     The breakers acquired the "CCC" certificates approved by CQC (China Quality Certification centre),and named as"China top brand"products   Application environment condition ----------------------------------------------- Ambient temperature:-5℃~+40℃ Elevation≤2000m. Relative humidity:not exceeding 50% at the maximum ambient temperature of +40℃.With lower temperature,higher humidity would be permitted,but the lowest average temperature in a month not exceeding 90% in that month,and giving consideration to the dews on the goods surface,which would appear due to temperature change. Pollution protection:3 grade Be suitable in electromagnetic environment A. Be able to bear the influcence of moisture in the air  or salt fog and oil fog or mould or nuclear industry environment The gradient≤±22.5℃ Be working reliably when earthquake(4g) occurring   Type and meaning ------------------------------------ YE M 1 (X) - (Y) YE----Zhejiang Yuye Eletrical Co.,ltd M----Moulded circuit breaker 1----Design Code X:     E:Series Moulded Case Electron Circuit Breaker     L:Series Moulded Case Earth Leakage Circuit Breaker Y----Rated frame graded current       Why choose us: 1.
