    Description

    TeSys D instantaneous auxiliary contact block, for contactors LC1D, LC1F and control relays CAD. It provides 3NO+1NC contacts (NC mirror certified) rated up to 10A/690V AC, connection by screw clamp terminals. Clip-on front mounting, it procures high reliability and durability. Multi standards certified (IEC, UL, CSA, CCC, EAC), Green Premium compliant (RoHS/REACh).

    Features

    • The Schneider Electric TeSys LADN31 is a high-performance auxiliary contact block designed to snap directly onto the front of a TeSys D contactor or control relay. It provides an immediate expansion of your control circuit capacity, allowing you to trigger additional signaling, interlocking, or status-monitoring functions without the need for separate, bulky relays.
    • his unit features a 3NO + 1NC (3 Normally Open / 1 Normally Closed) configuration. This specific arrangement is ideal for complex Canadian industrial control schemes where multiple "Open" signals are needed for PLC inputs or indicator lights, while the single "Closed" contact provides a dedicated safety interlock or "ready" status loop.
    • Engineered for rapid deployment, the LADN31 utilizes a tool-free, snap-on mounting system. It mounts centrally on the front of LC1D contactors, maintaining a compact depth profile that is essential for high-density DIN-rail layouts in crowded automation cabinets and motor control centers (MCCs).
    • Featuring high-integrity serrated sliding contacts, this block ensures a reliable electrical connection even in dusty industrial environments. It is rated for a minimum switching capacity of 5mA at 17V, making it a "PLC-ready" solution that prevents signal loss or "ghosting" when interfacing with sensitive electronic controllers.
    • Built to the rigorous standards of the TeSys D range, this auxiliary block is designed for millions of mechanical operations. Its robust construction ensures that your control feedback remains accurate and responsive, even in high-speed Canadian manufacturing, packaging, or HVAC applications where equipment cycles frequently.
