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.
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.
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
Is the voltage code BD3 valid for a CA3DN40 relay?
Issue:
Is the voltage code BD3 valid for a CA3DN40 relay?
Product Line:
Tesys Relays
Environment:
All Products
Cause:
Product selection
Resolution:
No. The voltage code BD3 is for the CA4D Low Consumption relays only. A 24 volt DC coil with built in transient suppression is not available on the CA3D relay. Use the add on LA4DA1E varister style or the LA4DC1U diode style add on transient suppressors on the CA3D relays.
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.
