New Original Fearlie M3056 AC Current Switch<\/h1>\n

Product Overview<\/h2>\n

The Fearlie M3056 is an AC current\u2011sensing switch adopting mutual induction principle. It can detect the alternating current of load cables passing through its built\u2011in aperture. This unit works without external auxiliary power supply and changes its contact state once the monitored current reaches the preset threshold. It is extensively applied in industrial cabinet control, motor running status detection, pump and fan monitoring, equipment interlock triggering and fault alarm systems. The compact housing allows convenient installation inside control cabinets and automation machinery for real\u2011time load current monitoring.<\/p>\n

Main Functions<\/h2>\n
    \n
  1. Detect AC load current through through\u2011hole wiring and trigger switch action when current exceeds the set threshold.<\/li>\n
  2. Provide contact switching output to send status signals to PLC, intermediate relays and alarm devices.<\/li>\n
  3. Self\u2011powered induction operation, no separate power supply needed for normal operation.<\/li>\n
  4. Visual LED indicators show working status for quick on\u2011site inspection and fault diagnosis.<\/li>\n
  5. Realize equipment running confirmation, overload early warning and interlock protection for AC\u2011driven devices.<\/li>\n
  6. Adjustable trigger current accommodates different field load monitoring requirements.<\/li>\n<\/ol>\n

    Technical Features<\/h2>\n
      \n
    • Mutual\u2011induction self\u2011powered design, electrical isolation between detected primary circuit and output secondary circuit.<\/li>\n
    • Adjustable current trigger point via built\u2011in potentiometer.<\/li>\n
    • Compact flame\u2011retardant ABS housing with mounting holes for fixed installation.<\/li>\n
    • Fast response and stable hysteresis performance to avoid frequent false triggering.<\/li>\n
    • Long service life with high switching cycle capacity.<\/li>\n
    • LED indicator for status visualization.<\/li>\n
    • Suitable for general industrial ambient conditions.<\/li>\n
    • Low heat generation during continuous long\u2011term operation.<\/li>\n<\/ul>\n
