Is the voltage code BD3 valid for a CA3DN40 relay?
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.
