FAQ
When is a 3RT1 needed instead of a 3RT2?
Choose 3RT1 for currents above the 3RT2 range, which tops out at 160 A. The 3RT1 range in this collection starts at 115 A.
Do the coils need a separate supply?
Check the coil suffix. It sets the control voltage and AC or DC operation.
Do you ship contactors outside Turkey?
Yes. Stoklink ships worldwide from Turkey on EXW terms. Lead time depends on distributor stock, so send the part numbers for a quote. Project quantities are quoted on request.
