26/07/2018

Issue:
Identifying the difference between LAD4TB and LAD4TBDL

Product Line:
IEC contactors and starters

Environment:
Products sold and used in the United States

Cause:
Identifying the difference between two similar part numbers

Resolution:
The LAD4TB is for 24V AC coils for the Tesys Series LC1D09 through LC1D38 contactors when supplied with G7 voltage code. The LAD4TBDL is 24 vdc bi-directional diode offered as a replacement if for some reason the diode supplied with the Tesys LC1D09 through LC1D38 contactors when ordered with BD or BL voltage code breaks or is no longer working.
