      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
       

      What the DC current contact ratings for the CAD50, CAD32, CAD503, CAD323, CAD506, and CAD326 relay?

      Issue:
      Checking on the DC current contact ratings for the CAD50, CAD32, CAD503,  CAD323,  CAD506, and  CAD326 relay.

      Product Line:
      CAD Industrial Relays

      Environment:
      Relays and Timers

      Resolution:
      Inductive:
      125V DC - 0.55 Amps make and break, 2.5 Amps cont.
      250V DC - 0.27 Amps make and break, 2.5 amps cont.
      600V DC - 0.10 Amps make and break, 2.5 Amps cont.

      Will the LA4DC1U work with the new CAD32BD relay?

      Issue:
      Will the LA4DC1U work on the CAd32BD relay

      Product Line:
      IEC relays and accessories

      Environment:
      Products sold and used in the United States

      Cause:
      Identifying product compatibility

      Resolution:
      The CAD32BD with DC coil has built-in coil suppression protection as standard so the LA4DC1U is not needed.


      CTA-ID : 2031917

      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.

      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. 
       

      Will the LA4DC1U diode suppressor mount to current Tesys D DC coils?

      Issue:
      Will the LA4DC1U diode suppressor mount to current Tesys D DC coils?
      Product Line:
      IEC contactors and starters

      Environment:
      Products sold and used in the United States

      Resolution:
      No. The LA4DC1U diode unit will only fit the older TeSys D contactors. Tesys D DC coils include suppression automatically, it`s not needed.
