It carries a CLASS 10 bimetal overload and is rated for 3.2 A at AC-3 duty at 400 V — the motor-switching current that governs real-world sizing for reversing applications. The operating voltage range is 340...440 V AC, with control voltage supplied at 184...253 V AC at 50 Hz or 196...253 V AC at 60 Hz. The IP55 enclosure means it handles dust and water jets — suited for panel-mount or standalone installation in industrial environments where washdown is not required. ## No fieldbus — standalone reversing control This starter carries no PROFINET, PROFIBUS DP, or AS-Interface protocol support. It is a standalone unit with 2 digital inputs for forward/reverse control. The design is electromechanical switching with short-circuit protection via circuit breakers. For applications requiring network integration, a fieldbus-capable SIRIUS variant would be needed. Dimensions are 145 mm depth, 182 mm width, and 220 mm height. The IP55 rating permits installation in enclosures without additional sealing for dust and splash protection.","metaTitle":"Siemens 3RK4353-3HR58-1BA0 SIRIUS MCU Reversing Starter","metaDescription":"Siemens SIRIUS 3RK4353-3HR58-1BA0 MCU-controlled reversing motor starter, 3.2 A at AC-3 400 V, CLASS 10, IP55.
