Frequently Asked Questions
Q: What is the difference between the SFD11-25A and SFD11-32A rotary load switches?
A: The primary difference is the rated current capacity. The SFD11-25A is rated for up to 25 amps, making it suitable for lighter industrial or commercial loads, while the SFD11-32A supports up to 32 amps for heavier machinery or equipment. Both operate at 380V AC / 50Hz and share the same universal rotary knob design.
Q: Is this rotary switch compatible with three-phase 380V systems?
A: Yes. The SFD11 universal rotary load switch is rated at 380V AC, 50Hz, making it fully compatible with standard three-phase industrial power systems commonly used in workshops, factories, and commercial buildings.
Q: Can this switch be used as a main power disconnect on a machine control panel?
A: Absolutely. The SFD11 series is specifically designed as a load disconnect (circuit isolation) switch for machinery and control panels. Its rotary knob mechanism provides a clear, reliable on/off action suitable for use as a main isolator or emergency cutoff switch on industrial equipment.
Q: What amperage options are available for the SFD11 series?
A: The SFD11 series is available in 25A, 32A, 40A, 63A, 80A, and 100A ratings, allowing you to select the correct switch for your specific load requirements.
