Introduction
I. Applicable Range
The SF series DIN-rail installation micro changeover switch
is a state-of-the-art switch apparatus,
perfectly tailored for hybrid resistance and impedance
circuits operating at AC frequencies of 50Hz or 60Hz, supporting a rated voltage below
230-400V, and a robust current range of 16A to 125A.
,
enabling
smooth, uninterrupted conversion between dual power sources or loads, facilitating
highly efficient circuit transition and switch
disconnection. This switch is the ultimate solution for the seamless transition
of power supplies for electrical
equipment and the changeover of
positive and reverse motor functions, precise measurement
of return circuit voltage, and alterations in phase of
current. This product adheres fully to the rigorous standards
IEC60947-3 and EN60947-3, ensuring top safety and performance.
II. Product FeaturesThe DIN-rail installation micro changeover switch
facilitates direct changeover between O, I, and II positions
using a manual handle. The handle's internal turning slot and the spindle's
sliding position are meticulously coated with superior lubricant to
reduce mechanical wear to a minimum. Both dynamic and static
contacts utilize an optimized contact method, ensuring
maximum conductivity and unwavering stability. Its modular and
standardized guide installation structure makes it ideally
suited for terminal combination apparatus in matching circuits, offering ultimate compatibility.
