New Original Schneider LADN22 TeSys D Instantaneous Auxiliary Contact Block<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
The LADN22 is an original Schneider Electric plug-on instantaneous auxiliary contact block belonging to the TeSys D contactor series product family. It is a modular accessory specially designed to be mounted directly on the top or side of TeSys D type AC and DC contactors, as well as compatible thermal overload relays. This brand-new genuine component provides auxiliary signal switching independent from the main power contacts of contactors. It is widely applied in industrial control cabinets, motor control circuits, automation panels, HVAC control systems, pumping equipment, conveyor control and general electrical interlock logic circuits, used to feedback contactor working status, realize electrical interlocking, indicator lamp driving and PLC signal input transmission. With standardized mechanical interface, it features quick assembly without extra wiring modification, stable contact performance and long service life for continuous industrial control operation.<\/div>\n<\/div>\n
\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Contactor Status Signal Feedback<\/strong>\n
    <\/div>\n

    Transmits real-time on\/off state of the main contactor: closes auxiliary contacts when the contactor coil is energized and main poles close; opens auxiliary contacts when the contactor de-energizes, to drive panel indicator lamps showing running or standby status.<\/li>\n

  2. Electrical Interlock Control<\/strong>\n
    <\/div>\n

    Utilizes normally open and normally closed contacts to build interlock logic for two mutually exclusive contactors, preventing simultaneous closing of forward and reverse contactors in motor reversing circuits to avoid short-circuit risks.<\/li>\n

  3. Remote Signal Transmission for Automation System<\/strong>\n
    <\/div>\n

    Sends switching signals to PLC input modules, relays or intermediate control loops, realizing automatic sequential control, fault judgment and remote monitoring in automated production lines.<\/li>\n

  4. Auxiliary Circuit Switching Control<\/strong>\n
    <\/div>\n

    Switches small-current auxiliary loads such as small solenoid valves, signal buzzers and miniature relay coils within its rated contact capacity range.<\/li>\n

  5. Plug-and-play Modular Expansion<\/strong>\n
    <\/div>\n

    Supports stacked assembly of multiple auxiliary contact blocks on one contactor to expand the quantity of auxiliary contacts according to customized control logic requirements.<\/li>\n<\/ol>\n<\/div>\n

    Structural & Performance Advantages<\/h3>\n<\/div>\n
    \n
      \n
    1. Snap-on Quick Mounting Structure<\/strong>\n
      <\/div>\n

      Precision buckle design enables direct clamping onto designated reserved slots of TeSys D contactors, no screws or tools required for installation and replacement, greatly improving on-site wiring efficiency.<\/li>\n

    2. Silver Alloy Contact Material<\/strong>\n
      <\/div>\n

      High wear-resistant silver alloy contact tips effectively resist electric arc ablation, reduce contact oxidation and contact resistance drift, ensuring stable signal transmission for long-term frequent switching.<\/li>\n

    3. Flame-retardant Engineering Plastic Housing<\/strong>\n
      <\/div>\n

      V0 grade flame-retardant insulated shell with high temperature resistance, anti-aging and anti-tracking performance, improving safety under continuous long-hour operation.<\/li>\n

    4. Independent Isolated Contact Chambers<\/strong>\n
      <\/div>\n

      Each NO and NC contact is placed in separated enclosed chambers to avoid short-circuit between adjacent contacts caused by arc splash or carbon accumulation.<\/li>\n

    5. Clear Terminal Marking Identification<\/strong>\n
      <\/div>\n

      Clear printed terminal codes on wiring terminals for fast wiring identification, effectively preventing wrong wiring during assembly and maintenance.<\/li>\n

    6. Mechanical Synchronization Consistency<\/strong>\n
      <\/div>\n

      All four contacts act synchronously with contactor main poles without action delay, guaranteeing accurate logic execution for interlock and signal feedback circuits.<\/li>\n<\/ol>\n<\/div>\n
