Schneider Electric LA4DT0U Contactor Timer Module

Product Description

The SCHNEIDER ELECTRIC LA4DT0U is a contactor timer module designed to add timing control functionality to compatible TeSys D series contactors. It mounts directly onto the contactor body as an accessory, enabling delayed or timed operation without additional external timers or relay wiring. At 0.11 pounds and compact dimensions of 2 inches by 1.9 inches by 1.6 inches, the LA4DT0U is a space-efficient solution for panel builders and industrial electricians integrating time-delay logic into motor control circuits. It is a standard replacement and upgrade component for existing TeSys D installations.

The LA4DT0U is used in motor control centers, control panels, and industrial automation applications where timed contactor operation is required. It is suited for both new panel builds and field retrofits on existing TeSys D contactor installations. Electricians and control panel technicians working on HVAC equipment, pump systems, conveyor controls, and general motor starters will find this module appropriate for adding on-delay or timing sequences directly at the contactor without expanding panel footprint.
