2018 China New Design MCB switch - Micro changeover switch – DaDa

l. Applicable range SF series DIN-rail installation micro change-over switch is a kind of switch apparatus applicabl to the hybrid resistance and impedance circuit with AC 50Hz or 60Hz, rated voltage below 230-400V andrated current16A-125A, allowing for 2 power sources or load conversion,realizing the functions of circuit conversion andswitch disconnection. It can be used for the changeover of power supply of electrical equipments,changeover of positiveand reverse running of motor, measurement of voitage of return circuit and phase change of currentetc. The product conforms to the standard IEC60947-3and EN60947-3 II. Product features The DIN-rail installation micro change-over switch realizes the changeover of O, l and Il pasitions directly with manual handle. The turning slot of the internal handle and the sliding position of the spindle are all coated with high grade lubricant to reduce mechanical wear. The dynamic and static contact adopt the reasonable contact method with good conductivity and stability. The modular and standard guide installation structure is particularly suitable for the matching circuit of terminalcombination apparatus
