LR9F Solid State Overload Relays - Selection
Three-Phase Overload Relays
Lug Kits
Lugs can be ordered either individually or in sets of six. In some cases the LR9F overload relay mounted
directly on the bottom of LC1F contactor will require a different size lug than the contactor itself. Refer
to the table below to select the appropriate 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
pre-packaged set of six lugs. If the two sizes are different, order 3 of each size lug. Mounting hardware
(screws, washers, nuts) are provided with the contactors and overload relays, not with the lugs.

Insulated Terminal Blocks
For contactors LC1F115, LC1F150, and LC1F185, an available touch-safe terminal block may be used
in place of lugs for power connections

Customer to obtain from local supplier.
When mounting overload relays LR9F5 57 to LR9F5 71 directly beneath the contactor it is recommended that the relays be additionally supported
by a mounting plate. For sizes LR9F5 75 to LR9F7 81 use of the supporting mounting plate is mandatory. See page 221 for selection table.
IEC standard 60947-4 specifies the following trip times when the overload relay senses 7.2 times the setting current:
Class 10: between 4 and 10 seconds
Class 20: between 6 and 20 seconds
Interconnection kit LA7F407 is required to mount an LR9F 71 to an LCIF185.
