Siemens 3RK1304-0HS00-6AA0 is a SIMATIC motor starter, designed as a maintenance switch for direct-on-line motor control. It handles 25 A at 400 V AC and carries a 50 000 A rated short-circuit current at 400 V — that SCCR means it can interrupt a fault up to that level without cascading upstream, so verify the available fault current at the panel. The supply is 24 V DC, with a permissible range of 20.4 to 28.8 V. IP65 enclosure means the housing and the M12 connectors (-) handle washdown — suitable for food-and-bev or wet-area deployment on a conveyor line. Screw fixing to a sub-panel or machine frame; mounting position is any. Operates from -25 to +55 °C; storage and transport range is -40 to +70 °C. Vibration resistance 2g, shock 15g / 11 ms. Pollution degree 3 — industrial environment with conductive dust.
Dual-protocol fieldbus onboard: PROFINET and PROFIBUS DP. The motor starter occupies 1 byte of input data; no digital I/O on the device itself (-) — all control goes over the fieldbus. Brake control options are absent: no 24 V DC, 180 V DC, or 230 V AC brake control. Four M12 sockets for digital input signals (-). Main energy infeed uses a socket according to ISO 23570. Dimensions: 170 mm deep, 110 mm wide, 230 mm high.
