Siemens 3RA6813-8AC Infeed Left Connection Unit

Siemens 3RA6813-8AC Infeed Left Connection Unit is a Sirius 3RA6 motor-starter accessory that provides the left-side main-circuit infeed for direct-on-line starters, combining a screw-terminal input with three slots for outgoing feeders on the load side. Conductor terminals accept up to 50 mm2 / 70 mm2 conductors, with the outgoing feeders designed for spring-terminal connections across three slots for compact load feeders. This left-infeed module is intended for use with DOL motor starters within the Sirius 3RA6 family and is commonly installed in control cabinets to streamline wiring and provide a dedicated left-feed path for the starter assembly.
