    Description

    TeSys D instantaneous auxiliary contact block, for contactors LC1D, LC1F and control relays CAD. It provides 1NO+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

    • he LADN11 is a clip-on auxiliary contact module from the Schneider Electric TeSys Deca (formerly TeSys D) range. It is used to add extra signaling circuits to a contactor without taking up extra space on the DIN rail.
    • his module provides 1 NO (Normally Open) + 1 NC (Normally Closed) instantaneous contacts. The NO contact is typically used for status signaling (like turning on a "Run" light). The NC contact is often used for electrical interlocking (preventing two contactors from closing at the same time).
    • The LADN11 features a front-mounting design. It snaps directly onto the face of a TeSys Deca contactor (models LC1D09 through LC1D150). This "one-click" installation requires no tools and automatically aligns the auxiliary actuator with the contactor's internal plunger.
    • These contacts are designed with high-reliability "serrated" wiping action. This makes them excellent for switching low-level signals used by PLCs (Programmable Logic Controllers) while still being robust enough to handle standard industrial relay logic.
    • The LADN11 is built for high-cycle industrial environments, with a mechanical durability of up to 30 million cycles. It is UL Listed, CSA Certified, and features IP2x "finger-safe" screw terminals to protect technicians during maintenance.
