The 690 V operational voltage covers 25–400 Hz circuits, so it works across 50/60 Hz supplies and into higher-frequency control schemes. Minimum switching capability is 5 mA at 17 V — low enough to reliably switch solid-state inputs or PLC digital cards without contact wetting issues. Front-mounted onto the contactor body, the block adds 42 mm depth, 26 mm width, and 48 mm height to the assembly. Snap-in terminals accept 1–4 mm² flexible or rigid wire (with or without ferrules) — no tools beyond a screwdriver for the cage clamp. Certified to EN/IEC 60947-5-1, UL 60947-5-1, and CSA C22.2 No 60947-5-1 for control-circuit devices. Also complies with GB/T 14048.5 (China), EN 50012 (proximity switch interface), and IEC 60335-1 Clause 30.2 / IEC 60335-2-40 Annex JJ for glow-wire / hot-wire ignition resistance in appliance circuits. For a BOM freeze or second-source gate, the LADN20A is the standard 2NO front-mount auxiliary for TeSys Deca contactors — no direct pin-compatible substitute exists outside the Schneider TeSys family, so the RFQ should confirm the exact contactor frame and terminal style.","metaTitle":"Schneider LADN20A TeSys Deca Auxiliary Contact Block, 2NO, 1","metaDescription":"Schneider LADN20A TeSys Deca auxiliary contact block, 2NO, front mount, snap-in terminals.
