TeSys D, Contactor Bi-Directional Limiting Diode
Item Number: LAD4TB
TeSys Deca suppressor module, for LC1D09-D38, LC1DT20-DT40 contactors and CAD control relays. To be used with 12-24V AC control circuit voltage, it provides a bidirectional peak limiting diodes protection limiting the transient voltage to 2 Uc max. Clip-on side mounting, overall size of the contactor is unchanged.

Frequently Asked Questions
What is the difference between the LAD4TB and LAD4TBDL bi-directional peak limiting diode?
Hide ShowIdentifying 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.
