It combines a reversing contactor, bimetal overload relay, and PROFIBUS DP communication in a single IP65 enclosure — meaning it mounts directly on the machine or conveyor section, not in a central panel. Rated 2.2 kW at AC-3 duty at 400 V, with a setting range of 4.5 to 6.3 A, this starter is sized for small three-phase motors — pumps, fans, roller drives — where reversing is needed and the motor protection must be local. The bimetal overload provides thermal protection matched to the motor's heating curve. Operating voltage is 400 to 500 V AC, and the unit carries a 50 A short-circuit breaking capacity (Icu) at 400 V — enough to clear a fault before upstream devices trip, provided the branch circuit is coordinated per the manufacturer's selectivity tables. ## Fieldbus and brake integration PROFIBUS DP is onboard — no external gateway needed. The starter communicates motor status, fault flags, and current draw directly to the PLC over the bus. This saves a remote I/O drop and simplifies wiring on distributed architectures like ET 200X. A motor brake output is integrated, controlled by the same logic that drives the contactor coils. For applications with holding brakes (vertical conveyors, gantries), this eliminates a separate brake rectifier and interposing relay. The brake supply is internal, AC 400 V, fed through the 9-pole motor feeder. ## Enclosure, mounting, and wiring The enclosure is self-contained; no additional cabinet is required. Dimensions are 140 mm wide, 270 mm high, and 134 mm deep. Main circuit connections use tab terminals (fast-on type), typical for distributed starters where quick disconnect is valued. The 9-pole motor feeder and 9-pole power connection are part of the assembly. Ambient operating temperature range is 0 to 55 °C — standard for industrial enclosures without forced cooling. Below 0 °C the bimetal trip characteristics shift; the starter should not be commissioned in freezing conditions.","metaTitle":"Siemens 3RK1300-1GS01-1AA3 Reversing Starter, 4.5-6.3A, IP65","metaDescription":"Siemens 3RK1300-1GS01-1AA3 EM 300 RS reversing starter. 4.5-6.3A setting range, 2.2kW at AC-3 400V, IP65, PROFIBUS DP, integrated brake contact.
