Product DescriptionProduct Overview40A 63A 100A 125A 250A 400A 630A 3 Pole 4 Pole Moulded Case circuit breaker MCCB
GSL1 series residual current operated circuit -breaker(hereafter simply reffered to as breakers) are one of the new type of breakers which have been developed by the company using advanced design and manufacturing technology.The rated insulation voltage of the breakers is 800V,suitable for turn-on of turn-off not frequently in the circuit of AC50Hz，rated working voltage 400V and rated working current up to 630A. The breakers equipment against damage may caused by long -term existed earth fault, which can't be examined by the over-current protection device.
Product feature △ The breakers have the following characteristics: compact size,high breaking capacity, short arc -over distance and shakeproof,etc. △ The breakerscould be installed vertically(upring) or horizontally(transverse). △ The breakers can't be fed inversely,only allowing 1,3,5 connect with power supply wires,2,4,6 connect wth load wires. △ The breakers are applicable to isdation, its corr- esponding symbol is shown as“ ”. ■ The breakers comply with the demands of the following standards; △ IEC60947-1 and GB14048.1General △ IEC60947-2 and GB14048.2Low voltage breakers and appendix B MCCB with residual current protection △ IEC60947-4-1 and GB14048.4Electro-mechanical contactors and motor starters △ The breakers acquired the "CCC" certificates approved by CQC (China Quality Centification Center) Applied environment △ Elevation of installtion site:≤2000m；Ambienttemperature:-5℃～＋40℃，and average temperature in 24 hours below +35℃(except special ordering). △ Relative humidity:not exceeding 50% at the maxinum ambient temperature of +40℃.With lower temperature higher humidity would be permitted, for example,reaches 90% at the dews on products surface due to temperature change. △ Pollution protection :Grade 3. △ Installing categoties:Ⅲ for breakers' main circuits; Ⅱ for auxiliary circuit and control circuit without connecting with main circuit. There must be not any explosive medium,and there must be not any gas which would destroy the insulation. △ The place would not be invaded by rain and snow. △ The breaker should bu installed according to stipulations in operations in operation manual.
