Schneider Electric LA3DR2 Off Delay Auxiliary Contact Block

The Schneider Electric Telemecanique LA3DR2 Off Delay Auxiliary Contact Block delivers adjustable off-delay timing for contactors in industrial motor control, enabling precise sequencing in equipment such as conveyors, pumps, compressors, HVAC, and packaging lines. As part of the TeSys D family, it provides 1 normally open and 1 normally closed contact with an adjustable time-delay from 0.1 to 30 seconds and a conventional free-air current (Ith) of 10 A. It supports up to 690 VAC (25–400 Hz) for Ue, with insulation rated at 690 VAC (IEC) or 600 VAC (UL/CSA); AC-15 current is 6 A at 120 VAC and 1.04 A at 690 VAC, and it mounts on the panel front with screw clamp terminals for easy wiring. Compatibility includes TeSys D (LC1D, CAD) and TeSys F (LC1F, CR1F) contactors and control relays, with protection rating IP2X and compliance to IEC 60947-5-1, EN 60947-5-1, UL 60947-5-1, CSA C22.2 No. 60947-5-1, and GB/T 14048.5, plus UL, CSA, CCC, IECEE CB Scheme certifications. This device is commonly used in motor control centers, automation systems, and electrical control panels where dependable delayed switching and process sequencing are essential.
