The TeSys Deca range of contactors and GV2ME circuit breakers with spring terminals are compatible with TeSys Quickfit.
To specify a contactor with spring terminals, a 3 is added to the part number before the coil voltage. For example, an 18a AC-3 rated contactor with a 110v AC coil would be LC1D18F7. With spring terminals, this part number is LC1D183F7.
