It switches a 1.5 kW motor at 400 V under AC-3 duty, covering a current adjustment range of 0.60 A to 4.00 A. The IP65 enclosure means this unit mounts directly on the machine frame or conveyor section — no separate control cabinet needed for washdown zones. The 100 kA short-circuit breaking capacity at 400 V (Icu) tells you this starter can ride through a fault upstream without blowing its internal fuse — critical for selectivity in a multi-drop AS-Interface segment. The solid-state switching contact means no mechanical wear on the main path, so the rated service life is defined by the electronics, not contact erosion. Full motor protection (electronic overload) eliminates the need for a separate thermal relay in the circuit. Integrated motor brake output (400 V AC / 0.75 A) handles the holding brake directly, saving an external contactor. Four digital inputs at 24 V DC are onboard for local sensors or pushbuttons. The AS-Interface protocol connection means this unit communicates over the same two-wire cable that carries power — no separate PROFIBUS or Ethernet drop required. Main circuit connection uses tab terminals — expect faston-style crimp lugs, not screw clamps. The housing measures 130 mm wide by 250 mm high by 107 mm deep, sized for the ECOFAST R2SS form factor. Ambient temperature range is -20 to +40 °C during operation, so keep it out of direct sun or near ovens. The touch-protected Han Q4/2 and Han 10E connectors on the description suggest pre-wired cable assemblies for the AS-Interface bus and motor power.","metaTitle":"Siemens 3RK1323-6ES84-3AA3 ECOFAST Reversing Starter, 1.5 kW","metaDescription":"Siemens ECOFAST R2SS reversing starter, 1.5 kW at 400 V AC-3, solid-state switching, AS-Interface, IP65, 0.6-4 A, 100 kA breaking capacity.
