Operating voltage for the power circuit is 340...440 V, so it's at home on 400 V nominal three-phase systems. Short-circuit protection is designed for circuit-breakers upstream — the starter itself has no integral SCCR rating listed, so coordinate the upstream breaker per Siemens' selectivity tables to keep the fault energy within the starter's withstand. The 3-pole main current circuit handles the three-phase motor load.","metaTitle":"Siemens 3RK4353-3ER58-1BA0 SIRIUS Reversing Starter","metaDescription":"Siemens SIRIUS reversing motor starter, 1.6 A at 400 V AC-3, Trip Class 10, IP55.
