When mounting overload relays LR9F5*57 to LR9F5*71 directly beneath the contactor, supporting the relays with a
mounting plate is recommended. With overload relays LR9F7*75 to LR9F7*81, use of a support mounting plate is
mandatory.

Interconnection kit LA7F407 is required to mount an LR9F5*71 to an LC1F185.
NOTE: This table lists the maximum SCCR of the component when protected by any circuit breaker or fuse. If the
maximum component SCCR is 65 kA and a 25 kA rated circuit breaker is used, then the system will be 25 kA as the
circuit breaker becomes the weakest link.
