Motor protection is handled by a bimetal overload relay built into the unit — a thermal-mechanical trip that tracks motor heating and resets after a cool-down, common on this class of direct starter. It communicates over PROFIBUS DP, so it integrates into a Siemens S7 or third-party master as a remote I/O node for start/stop commands and status feedback — no separate fieldbus coupler needed. ## Where you'd use it The IP65 enclosure means the starter is built for washdown environments — food processing, packaging lines, or anywhere hose-down cleaning is routine. The housing and connectors tolerate direct spray without letting moisture into the electronics. It mounts via the backplane bus system (ISO 23570 socket) for both power and communication, so it's designed for a modular motor starter system on a DIN-rail or panel-mount backplane — not a standalone contactor you hard-wire point-to-point. The 24 V DC control supply (20.4 to 28.8 V range) powers the coil and the PROFIBUS interface — standard for industrial control panels with a 24 V DC bus.","metaTitle":"Siemens 3RK1300-1FS01-0AA0 Direct Starter, 5 A AC-3, IP65","metaDescription":"Siemens 3RK1300-1FS01-0AA0 direct starter, 5 A AC-3 at 400 V, 1.9 kW motor rating, IP65, PROFIBUS DP, bimetal overload, current lifecycle stage.
