Overview
The LADN223G is a Schneider TeSys Deca auxiliary contact block, order code LADN223G, with a 2 NO + 2 NC contact configuration rated for 6 A switching current. It mounts to the front of compatible TeSys Deca contactors and uses spring terminals for wiring.
This block provides four instantaneous contacts — two normally open and two normally closed — for signalling and interlocking circuits on TeSys Deca contactors. The 6 A switching current covers typical control loads such as PLC inputs, indicator lamps, and small relays. Rated making capacity is 140 A AC and 250 A DC per IEC 60947-5-1, with short-time ratings of 100 A for 1 s, 120 A for 500 ms, and 140 A for 100 ms at 60 °C.
Applications
Auxiliary contact blocks like the LADN223G are used in motor control centres, panel builder assemblies, and machine control cabinets to extend the signalling capacity of a contactor. Typical roles include status feedback to a PLC, enabling/disabling downstream devices, and forming interlock chains between contactors.
