Schneider Electric LADN13 Auxiliary Contact Block

Schneider Electric Telemecanique LADN13 Front-Mount Auxiliary Contact Block expands the control capabilities of TeSys D and TeSys Deca contactors with 1 normally open plus 3 normally closed auxiliary contacts for robust control, signaling, and electrical interlocking in industrial motor control systems. It is commonly used to extend contactor control in MCCs, conveyors, pumps, compressors, packaging machines, HVAC systems, and industrial control panels, ideal for repair, retrofit, or automation maintenance when paired with TeSys D LC1D contactors, CAD control relays, TeSys F LC1F contactors, or CR1F contactors. Key specifications include 1NO + 3NC with instantaneous auxiliary contact operation, front-mount (clip-on) mounting, and screw clamp terminals. Electrical ratings include Ue 690 VAC (25–400 Hz) and Ui 690 VAC (IEC) / 600 VAC (UL/CSA); Ith 10 A at 60°C; AC-15 rated current of 6 A at 120 VAC and 1.04 A at 690 VAC; DC-13 rated current of 0.55 A at 125 VDC and 0.1 A at 600 VDC. The device is rated for up to 30 million mechanical cycles and complies with IEC/EN 60947-5-1, UL 60947-5-1, CSA C22.2 No. 60947-5-1, and GB/T 14048.5, with certifications CB, UL, CSA, CCC, EAC, and UKCA.
