It integrates an electromechanical switching contact, bimetal overload protection, and a motor brake output into one IP65 enclosure, so it mounts directly on the machine frame rather than inside a central panel. The 0.3 A AC-3 rating at 400 V means it handles small induction motors up to 0.09 kW in that duty class — think conveyor drives, small pumps, or fan motors that start under load. The operating voltage range is 400 to 500 V, fed through an ISO23570 socket interface for main energy infeed and load-side outgoing feeder. For a 0.09 kW motor on 400 V three-phase, that lines up correctly. The IP65 enclosure means the unit withstands hose-directed water and dust ingress, so it is suited for washdown zones or dusty production floors without needing a separate cabinet. PROFIBUS DP communication runs over the backplane bus, which lets the starter integrate into a fieldbus network for remote start/stop and diagnostics. The bimetal overload relay provides thermal motor protection — a mature, field-proven method that tracks motor heating without needing a sensor on the windings. ## Integration notes for panel builders and MRO planners The control supply voltage is 24 V DC, with a permissible range of 20.4 to 28.8 V DC, so a standard 24 V DC panel supply works as long as it stays within that tolerance. The unit has no digital inputs or outputs on board, and neither is parameterizable — all control comes through the PROFIBUS DP fieldbus interface. Short-circuit protection is provided by circuit-breakers (not fuses), and the design includes a motor brake output, which is useful for applications requiring rapid stopping or holding torque at standstill. The backplane bus handles both communication and supply voltage transmission, so wiring is limited to the main power infeed and load-side connections via the ISO23570 sockets.","metaTitle":"Siemens 3RK1300-0DS01-0AA3 Direct Starter, IP65, 0.3A AC-3 a","metaDescription":"Siemens 3RK1300-0DS01-0AA3 direct starter, current lifecycle stage, IP65, 0.3A AC-3 at 400V, PROFIBUS DP, bimetal motor protection.
