Description

TeSys Deca instantaneous auxiliary contact block, for contactors LC1D, LC1F and control relays CAD. It provides 2NC 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. LADN02 is a Schneider Electric add-on auxiliary contact block for TeSys Deca and TeSys F contactors. Multi standards certified (IEC, UL, CSA, CCC, EAC). It can be used in safety applications thanks to its NC certified mirror contacts. Easy to mount on front by clip-on, it procures high reliability and durability. Available worldwide, it is multi-standards certified (IEC, UL, CSA, CCC, EAC, Marine). Add-on block with 2NC mechanically linked auxiliary contacts, with instantaneous operation. Suitable to be included in the control of safety systems thanks to its NC certified mirror contacts. High electrical durability , several millions of operating cycles in AC-14/AC-15/DC-13 according conditions. Mounting by clip-on on front of all TeSys Deca and TeSys F contactors.

Features

Featuring two normally closed (NC) instantaneous contacts, this auxiliary block is the industry standard for creating electrical interlocks and status signaling in complex control circuits. It provides a reliable mechanical "fail-safe" that prevents conflicting contactors from energizing simultaneously, protecting your motors from phase-to-phase shorts and ensuring smooth, sequenced industrial operations.
Engineered for seamless integration with the Schneider Electric TeSys Deca (formerly TeSys D) range, this module features a front-mounting clip-on mechanism that requires zero tools for installation. This "plug-and-play" design reduces panel assembly time and allows for rapid field upgrades without disturbing existing power wiring or increasing the footprint of your motor starter.
Built to endure millions of mechanical operating cycles, the LADN02 is designed for the rigorous environments of automated manufacturing and heavy-duty infrastructure. The high-conductivity serrated contacts provide a "wiping" action that clears dust and oxidation during every movement, ensuring consistent electrical continuity even in vibrating or dusty industrial enclosures.
Equipped with protected screw-clamp terminals, this auxiliary contact block meets IP2x "finger-safe" standards to prevent accidental contact with live electrical points during maintenance. This design choice not only simplifies compliance with OSHA and NFPA 70E safety regulations but also provides peace of mind for technicians performing routine inspections on energized control cabinets.
