The LA9F18517 is a 3-pole power connections set from the TeSys F range, designed as the star-delta connection accessory for TeSys F contactor assemblies. It provides the interconnecting power bus between the line, star, and delta contactors in a reduced-voltage motor start scheme.
Integration Note — TeSys F Star-Delta Assembly
This connection set mounts directly onto the TeSys F contactor base, linking the three poles in the star-delta configuration. It eliminates the need for separate wiring between contactors, reducing assembly time and potential wiring errors in the motor starter panel. Verify the specific TeSys F contactor frame size (F115, F150, F185) matches this accessory before specifying — the LA9F18517 is sized for the F185 frame.
