The LADN11R is a front-mount auxiliary contact block for Schneider TeSys Deca contactors. It adds one normally-open and one normally-closed contact to the contactor assembly, wired via screw-clamp terminals. Rated operational current is 6 A at 120 V AC-15 (control circuit duty) and 0.55 A at 125 V DC-13 (solenoid/brake duty). Conventional free-air thermal current is 10 A at 60 °C.
The block measures 42 mm deep, 44 mm wide, and 48 mm high. It mounts on the front of a TeSys Deca contactor — no DIN rail or separate panel space needed. Screw-clamp terminals accept 1 to 4 mm² solid or flexible wire (one or two conductors). Tightening torque is 1.7 N·m with a flat, Philips No 2, or Pozidriv No 2 screwdriver.
Switching capability and ratings
Minimum switching is 1 mA at 17 V, so it handles low-level PLC signals reliably. Rated making capacity is 140 A AC and 250 A DC per IEC 60947-5-1. Short-time withstand: 100 A for 1 s, 120 A for 500 ms, 140 A for 100 ms at 60 °C. Insulation voltage is 690 V (IEC) / 600 V (UL/CSA).
The LADN11R is certified to EN/IEC 60947-5-1, GB/T 14048.5, EN 50012, UL 60947-5-1, and CSA C22.2 No 60947-5-1. It also meets IEC 60335-1 Clause 30.2 and IEC 60335-2-40 Annex JJ for appliance applications. Protective treatment is TH per IEC 60068. IP2X finger-safe protection per IEC 60529.
