It combines two contactors with a bimetal overload relay in a single IP65 enclosure, so it handles forward/reverse motor control and overload protection in one package — no separate contactor-and-relay assembly needed. Rated operating voltage is 400 to 500 V AC, with a motor output of 4 kW in AC-3 duty (squirrel-cage motors) at 400 V. The setting range on the bimetal overload is 7.0 to 10 A, so it covers motors drawing that full-load current — the 7 A minimum and 10 A maximum are the adjustment limits, not the trip thresholds. This unit includes a motor brake output rated DC 500 V / 1 A, intended for internally supplied brakes — common on vertical-load conveyors or holding applications where the brake must engage when power is removed. Communication is via PROFIBUS DP, so it integrates into a Siemens S7-300/400 or ET 200X bus network without a separate gateway. ## Integration notes — panel and wiring The enclosure measures 134 mm deep by 140 mm wide by 270 mm high — a compact footprint for a reversing starter with integrated brake output and bus communication. Main current circuit connections use tab terminals (fast-on type), common in distributed I/O boxes where quick wiring and field replacement matter.","metaTitle":"Siemens 3RK1300-1JS01-1AA4 EM 300 RS reversing starter, 7-10","metaDescription":"Siemens SIRIUS 3RK1300-1JS01-1AA4 reversing starter, 7-10A setting range, AC-3 4kW/400V, IP65, PROFIBUS DP, with brake contact.
