Schneider Electric LADN40 Auxiliary Contact Block

Schneider Electric's LADN40 (LA1 DN40) TeSys auxiliary contact block expands control circuits by adding four normally open (4 NO) contacts with instantaneous operation to compatible TeSys D and TeSys F contactors. Designed for front-mount installation in industrial motor control panels, it features screw clamp terminals for robust wiring and is compatible with TeSys D LC1D09–LC1D150 and TeSys F LC1F/CR1F series. Rated up to 690 VAC (25–400 Hz) and insulation voltage of 690 VAC (IEC) / 600 VAC (UL/CSA), it offers 10 A Ith at 60°C and 140 A rms making capacity at ≤690 VAC, enabling dependable status feedback, electrical interlocking, and control circuit expansion in MCCs, conveyors, pumps, compressors, HVAC systems, and automated machinery. It complies with IEC 60947-5-1, UL 60947-5-1, and CSA C22.2 No. 60947-5-1 for industrial motor control and automation applications.
