Introduction
I. Applicable Range
Introducing the SF series, a line of cutting-edge DIN-rail installation micro solutions, the change-over switch represents an advanced switch apparatus, designed to be perfectly applicable to circuits with hybrid resistance and impedance, suitable for circuits operating on AC frequencies of 50Hz or 60Hz, with a rated voltage ranging from 230V to 400V and a rated current spanning 16A to 125A,ensuring optimal performance. This allows for seamless transitions between 2 power sources or load conversions, effectively enabling the robust functions of circuit conversion and efficient switch disconnection. Ideal for switching the power supply of electrical equipment, facilitating the changeover of power supply for various electrical devices, and managing the positive and reverse direction running of motors, as well as the precise measurement of voltage in return circuits and the advanced phase change of current, etc. This product is meticulously crafted to conform to
the high standards of IEC60947-3 and EN60947-3.
II. Product Features
This DIN-rail installation micro change-over switch adeptly facilitates the changeover between positions O, I, and II directly via manual handle, offering enhanced control and precision. The internal handle's turning slot and the spindle's sliding position are meticulously coated with high-grade lubricant to significantly reduce mechanical wear. The contacts-both dynamic and static- employ a logical contact method, ensuring excellent conductivity and stability. The modular and standard guide installation structure makes it particularly suitable for integration with terminal combination apparatus, optimizing the matching circuit.
