      What do the LA4D timing modules require for mounting on LC1D40A through LC1D65A contactors?

      Product Line:
       
      Tesys D line Contactors and Accessories

      Resolution:
       
      Mounting this module to TeSys LC1D40A through LC1D65A contactor requires the use of the LAD4BB3 wiring adaptor. This adaptor can be fitted only to contactors with no coil suppressor.
       

      Are the LAD703F coils rated for continuous duty?

      Issue:
      Continuous duty on a LAD703F.

      Product line:
      Tesys D IEC Contactors and Overload Accessories

      Environment:
      LAD703 remote stop or electrical reset
      LA7D03 remote tripping or electrical reset

      Cause:
      Customer was using competitor brand and it burns after 10 seconds

      Resolution:
      The time for which the coil of the remote tripping or electrical resetting device, LAD703 or LA7D03 can remain energized depends on the rest time in between energizing the coil. 
      Minimum pulse to energize is 200ms

      1 second pulse needs a 9 second rest time
      5 second pulse needs a 30 second rest time
      10 second pulse needs a 90 second rest time
      Maximum duration of energizing the coil is 20 seconds and would require a 300 second rest time. 
       

      What is the LA4DE1U alternative?

      LA4DE1U TeSys D - suppressor module - varistor - 110...250 V AC/DC

      to suit D40-D115 (3P) and D65-115 (4P):
      LA4DE2U TeSys D - suppressor module - varistor - 110...250 V AC
      OR
      LA4DE3U TeSys D - suppressor module - varistor - 110...250 V DC
       

      I have a LC1D12BD contactor and want to fit a LA4DFB to it

       You need to use a LAD4BB adaptor

      Part number LA4DFB not fitting on LC1D12 Contactor?

      Does LC1D80BD have internal bi-directional diode?

      Issue:
      LC1D80 and LC1D95 bi-directional diode

      Product Line:
      TeSys™ D Contactors

      Environment:
      Contactor Accessories

      Resolution:
      LC1D80 and LC1D95 does not have an internal bi-directional peak limiting diode on their DC coils. LA4DC3U (Screw connection of wire to the contactor coil terminals 24–250 Vdc, 3p-4p) must be ordered separately.

      The LC1D09 to LC1D38 have an internal diode by default on their DC coils.
