Description

TeSys Deca instantaneous auxiliary contact block, for contactors LC1D, LC1F and control relays CAD. It provides 2NO+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. TeSys Deca contactors have been designed for perfect integration into control systems. Multi standards certified (IEC, UL, CSA, CCC, EAC). TeSys Deca contactors offer quick simple setup, while maintaining a compact size. Contactors have both horsepower and Kw motor rating for international acceptance. An extennsive line of accessories makes it easy to meet the requirements of most applications. These contactors have UL, CSA, GOST, RINA, BV, CCC, DNV, GL, LROS certifications.

Features

The LADN22 is a TeSys Deca auxiliary contact block designed to expand the signaling capabilities of your motor starter. It snaps directly onto the front of a contactor, providing additional electrical paths to control indicator lights, signal a PLC, or manage complex interlocking logic without taking up any extra space on the DIN rail.
This unit features a 2 NO (Normally Open) + 2 NC (Normally Closed) configuration. This versatile "2-and-2" split allows industrial electricians to simultaneously handle multiple tasks such as "sealing in" a start circuit and providing a "running" status signal (using the NO contacts) while managing safety lockouts or fault indicators (using the NC contacts).
The LADN22 utilizes a tool-free, front-mounting system. It simply clips onto the face of any compatible TeSys Deca (LC1D) contactor. This "click-fit" design allows for rapid field upgrades or maintenance, as the block can be added or replaced in seconds without disturbing the main power wiring of the contactor.
Engineered with high-integrity contacts, the LADN22 is rated for a minimum switching capacity of 5mA at 17V. This makes it exceptionally reliable for modern automation systems, ensuring that even low-voltage signals sent to a PLC or digital controller are transmitted clearly and without the "contact bounce" issues found in lower-quality alternatives.
Featuring screw clamp terminals with captive cable clamps, this block ensures a gas-tight, vibration-proof connection. The terminals are IP20 finger-safe, protecting maintenance personnel from accidental contact while providing a robust electrical bond for wires ranging from #18 to #14 AWG.
