Schneider Electric LADN11 Auxiliary Contact Block

Schneider Electric TeSys D LADN11 Front-Mount Auxiliary Contact Block adds one normally open and one normally closed auxiliary contact to expand the control, signaling, and electrical interlocking capabilities of TeSys IEC contactors and control relays in industrial motor-control systems. It is designed for front-mount clip-on installation with screw clamp terminals and is compatible with TeSys D LC1D contactors, TeSys F LC1F and CR1F contactors, and CAD control relays. Key specifications include a rated operational voltage (Ue) of 690 VAC with 25–400 Hz, insulation voltage (Ui) of 690 VAC (IEC) / 600 VAC (UL/CSA), a conventional thermal current (Ith) of 10 A at 60°C, AC-15 current ratings of 6 A at 120 VAC and 1.04 A at 690 VAC, and DC-13 ratings of 0.55 A at 125 VDC and 0.1 A at 600 VDC. The block offers up to 30 million mechanical operating cycles and complies with IEC/EN 60947-5-1, UL 60947-5-1, CSA C22.2 No. 60947-5-1, with certifications including CB, UL, CSA, CCC, EAC, and UKCA. Commonly installed in MCCs, conveyors, pumps, compressors, packaging machines, HVAC systems, and other industrial control panels where dependable control, signaling, and interlocking are essential.
