The AC-3 rating of 2.5 A tells you it's sized for switching motors under full load, not resistive heaters; the bimetal overload release is field-adjustable from 1.8 to 2.5 A, so you set the trip point to match the motor nameplate FLA. The 3-pole main circuit connects via tab terminals, and the control supply is 24 V DC (20.4 to 28.8 V range). ## Integration into a PROFIBUS DP cell This starter communicates over PROFIBUS DP via the backplane bus — no AS-Interface or PROFINET onboard. The bus connection and supply voltage both route through the backplane, so the unit snaps onto a mounting rail and the bus coupler handles addressing. The IP65 enclosure means it can sit directly on the machine frame in a washdown zone, not just inside a sealed cabinet. Dimensions are 134 mm deep, 140 mm wide, 270 mm tall — factor that into your gland-plate layout if you're routing the ISO23570 socket for main energy infeed and load-side outgoing feeder. ## Short-circuit protection coordination The starter includes short-circuit protection via circuit-breakers (not fuses). This matters for selectivity studies: the upstream protective device must coordinate with the 2.5 A AC-3 rating to avoid nuisance tripping on motor start.","metaTitle":"Siemens 3RK1300-1CS01-0AA0 Direct Starter, 2.5 A AC-3, IP65","metaDescription":"Siemens 3RK1300-1CS01-0AA0 direct starter, 2.5 A AC-3 at 400 V, 0.9 kW motor rating, IP65, PROFIBUS DP, current lifecycle.
