Schneider Electric LA4DT4U Contactor Timer Module

Product Description

The SCHNEIDER ELECTRIC LA4DT4U is a contactor timer module designed to add time-delay functionality to compatible TeSys D series contactors. The module mounts directly onto the contactor body, allowing a licensed electrician or controls technician to introduce on-delay or off-delay timing into motor control circuits without adding separate DIN-rail timing relays. Measuring 2 inches in length, 1.9 inches in width, and 1.6 inches in height, the LA4DT4U is a compact add-on that integrates cleanly into panel assemblies where space is a constraint. It is used in industrial and commercial motor control applications wherever precise contactor switching sequences are required.

This timer module is suited for installation in motor control centers, panel boards, and machine control enclosures in both commercial and light industrial settings. It is typically installed during panel build or during a scheduled maintenance replacement of contactor accessories. Technicians working with TeSys D series motor starters will find this module fits directly within the existing contactor assembly without additional brackets or adapters. Compatible systems include the 3 Pole LC1D09-D38 Contactor, the 4 Pole LC1DT20-DT40 Contactor, and TeSys D series contactors.
