The Schneider LADN40A is a TeSys Deca auxiliary contact block with four normally-open instantaneous contacts, designed for front mounting on TeSys Deca contactors and reversing starters. It uses snap-in terminals accepting 1 to 4 mm² flexible or rigid wire. Rated operational current is 6 A at 120 V AC-15 (inductive solenoid loads) and 1.04 A at 690 V AC-15. For DC control circuits, it carries 0.55 A at 125 V DC-13 and 0.1 A at 600 V DC-13 — the DC-13 rating governs the real-world breaking capacity for DC solenoids and contactor coils.
Compliant with EN/IEC 60947-5-1, UL 60947-5-1, CSA C22.2 No 60947-5-1, GB/T 14048.5, EN 50012, and relevant clauses of IEC 60335-1 and IEC 60335-2-40. This covers control circuit applications in North America, Europe, and China without additional certification work.
Front-mounts onto TeSys Deca contactors and reversing starters. Dimensions are 44 mm wide, 42 mm deep, and 48 mm tall — fits within the standard contactor footprint without adding panel width. IP2X finger protection per IEC 60529. The snap-in terminals accept 1 to 4 mm² flexible wire with or without ferrules, and 1 to 4 mm² solid wire.
