Schneider Electric LA4DFB Contactor Interface Module

Product Description

The SCHNEIDER ELECTRIC LA4DFB is a contactor interface module designed for use in industrial motor control and power switching applications. It serves as an accessory that integrates with compatible TeSys D series contactors, providing the electrical interface needed to connect control signals to the contactor coil circuit. Weighing just 0.12 pounds and measuring 2 inches in length, 1.9 inches in width, and 1.6 inches in height, this compact module fits within tight panel layouts without requiring additional hardware modifications. Licensed electricians and industrial controls technicians are the primary installers of this component.

This interface module is intended for use in industrial and commercial electrical panels, motor control centers, and automation enclosures where TeSys D series contactors are deployed. It is compatible with LC1D09-D150 and TeSys D contactors, making it a direct accessory for that product family. Typical installations involve integrating PLC output signals or control circuit wiring into the contactor assembly, where the module provides a standardized electrical handoff point.
