That's the bimetal overload relay doing its job. It's a direct-on-line (DOL) design with electromechanical switching contacts and integrated short-circuit protection via circuit-breakers. The supply voltage range is 340…440 V AC, and the control coil takes 184…253 V at 50 Hz or 196…253 V at 60 Hz. One digital input is onboard — enough for a simple start/stop from a local pushbutton or PLC dry contact. ## IP55 and mounting — panel placement reality Dimensions are 182 mm wide, 220 mm high, 145 mm deep.","metaTitle":"Siemens 3RK4353-3HR58-0BA0 SIRIUS Motor Starter, 3.2 A AC-3","metaDescription":"Siemens 3RK4353-3HR58-0BA0 SIRIUS motor starter, 3.2 A at AC-3/400 V, Class 10 trip, IP55.
