Product details

Overview

The LADT0 is a pneumatic time-delay auxiliary contact block in the TeSys Deca range, delivering one normally-open and one normally-closed contact with on-delay timing for sequential motor control or interlocking circuits. Rated for 690 V insulation and 6 A switching current, it mounts directly on the front of TeSys Deca CAD and LC1D contactors, as well as TeSys F LC1F and CR1F frames.

Selection and comparison

Compared to the LAD8N11 instantaneous block (10 A rated, 2-pole), the LADT0 provides on-delay timing at 6 A with 1NO+1NC contacts — choose the LADT0 when a sequenced start or delayed dropout is required, and the LAD8N11 when only instantaneous mirroring of the contactor state is needed.
