Schneider Electric LADT0 Time Delay Auxiliary Contact Block

Schneider Electric LADT0 Time Delay Auxiliary Contact Block is a TeSys Deca accessory that adds a timed NO/NC auxiliary contact to TeSys D contactors. It provides 1 normally open (NO) and 1 normally closed (NC) contact, with an on-delay function that can be set from 0.3 to 3 seconds to sequence secondary circuits after the main contactor energizes. The block mounts on the front of TeSys Deca devices and uses screw clamp terminals for wiring, accommodating standard control-wiring conductors. Electrically, the LADT0 is rated up to 10 A at 690 V AC, making it suitable for control-circuit applications in industrial panels. It is designed for use with TeSys D contactors such as LC1D and LC1F, extending timing functions without requiring additional panel space. This auxiliary block is a compact solution for introducing a controlled delay in interlocking schemes, motor-start sequencing, or timed control logic within TeSys-based control panels.
