Control cabinets feature broad applicability in 50Hz AC low-voltage power systems with rated operating voltages up to 380V, and are equally suitable for 50Hz AC electrical systems below 500V, serving various functions including fire pump control, submersible sewage pump control, fire fan control, and lighting distribution control. They support multiple starting methods such as direct-on-line starting, star-delta reduced voltage starting, autotransformer starting, variable frequency drive (VFD) starting, and soft starter control.
