Lugs can be ordered either individually or in sets of 6. In some cases the LR9F overload relay mounted directly on the load side of an LC1F contactor will require a different size lug for your choice of contactor and overload. If all 6 lugs (three for line side of contactor, three for load side of overload relay) are the same, Square D offers a prepackaged set of six lugs. If the two sizes are different, order 3 of each size lug. Mounting hardware (screws, washers, and nuts) are provided with the contactors and overload relays, not with the lugs.
