It is a reversing starter, meaning it integrates two contactors with mechanical interlocking to reverse a three-phase motor without external wiring — a common requirement for conveyors, hoists, and actuator drives where direction change is needed. The 12 A AC-3 rating at 400 V is the motor-switching current; for resistive loads (AC-1) the unit can carry higher current, but the AC-3 figure is the one that governs motor duty. Operating frequency is rated at 80 operations per hour minimum — adequate for intermittent reversing cycles but not for high-speed jogging. Supply voltage range is 340…440 V AC, with a control voltage of 184…253 V at 50 Hz or 196…253 V at 60 Hz. This covers standard 400 V three-phase networks with a wide tolerance band. The unit has 2 digital inputs for control signals, and motor protection is via a bimetal overload relay. Short-circuit protection is designed for circuit-breakers, and the main current circuit has 3 poles. There is no integrated brake control (no 24 V DC, 180 V DC, 400 V AC, or 500 V DC brake output), so if the application requires a motor brake, an external brake control unit must be added. If a cross-reference is needed, the closest functional sibling in the SIRIUS family is the non-reversing base starter; the reversing function and the IP55 enclosure are the distinguishing features here. ## Panel and machine integration notes Dimensions are 145 mm deep, 182 mm wide, and 220 mm high. This is a self-contained unit — no DIN-rail mounting; it bolts directly to a mounting surface. The IP55 rating means it can be mounted outside a control cabinet, but the ambient temperature range of -25 to +35 °C must be respected; above 35 °C, derating applies. No fieldbus communication is built in — no PROFINET, PROFIBUS DP, or AS-Interface. Control is via hardwired digital inputs. For networked systems, an external gateway or a different SIRIUS variant with integrated bus would be required.","metaTitle":"Siemens 3RK4353-3PR58-1BA0 SIRIUS Reversing Starter","metaDescription":"Siemens SIRIUS 3RK4353-3PR58-1BA0 reversing motor starter, 12 A AC-3 at 400 V, Class 10, IP55.
