Introduction
I. Applicable Range
The SF series, designed for DIN-rail installation, offers a compact and efficient micro change-over switch. This innovative change-over switch serves as a highly reliable apparatus, ideally suited for both hybrid resistance and impedance circuits operating with AC frequencies of 50Hz or 60Hz, and a rated voltage of up to 230-400V, while supporting a current range from 16A to 125A., It seamlessly enables the transition between two power sources or load conversions, ensuring precise circuit conversion functions alongside reliable switch disconnection capabilities. It is adept for the changeover of power supplies in electrical equipment, as well as the switch over between forward and reverse motor operations, facilitating accurate voltage measurement of return circuits and phase alterations of current, among other applications. Conforming to standards
IEC60947-3 and EN60947-3, it ensures top-notch reliability and safety.
II. Product Features
This DIN-rail micro change-over switch effortlessly transitions between positions O, I, and II using its manual handle, providing smooth operation. The internal handle's turning slot and the spindle's sliding position are treated with high-grade lubricant to significantly reduce mechanical wear and tear. Its dynamic and static contacts are crafted with a method that ensures excellent conductivity and stability. The switch's modular, standardized guide installation structure is especially adapted to seamlessly integrate into terminal combination apparatus circuits, making it ideal for modern electrical systems. This design is particularly beneficial for the matching circuits of terminal combination apparatuses, ensuring optimum performance and reliability in a variety of applications.
