Schneider Electric LADN22 Auxiliary Contact Block

The Schneider Electric LADN22 Front-Mount Auxiliary Contact Block adds four auxiliary contacts (2 normally open and 2 normally closed) to TeSys D/Deca contactors for control, signaling, and electrical interlocking in industrial motor control systems. It clips on to the front of compatible devices and uses screw clamp terminals for reliable connections, with compatibility including TeSys D LC1D contactors, CAD control relays, TeSys F LC1F contactors, and CR1F contactors. Electrical ratings include Ue 690 VAC with a frequency range of 25–400 Hz, Ith 10 A at 60°C, AC-15 6 A at 120 VAC and 1.04 A at 690 VAC, DC-13 0.55 A at 125 VDC and 0.1 A at 600 VDC, and Ui 690 VAC (IEC) / 600 VAC (UL/CSA). It delivers up to 30 million mechanical operating cycles and is designed for robust signaling and interlocking in industrial control panels and automation systems. Common applications include MCCs, conveyors, pumps, compressors, packaging machines, HVAC systems, and other applications requiring dependable machine control and status indication.
