It operates on a 340–460 V AC motor circuit with a separate 20.4–26.4 V DC control supply, drawing power from the AS-Interface bus for communication and digital inputs. The IP54 enclosure means it's protected against dust ingress and splashing water — suitable for installation inside control cabinets on factory floors where occasional washdown mist or dust is present, but not for direct high-pressure spray. ## Mounting and integration into a panel Dimensions of 290 mm wide × 215 mm high × 205 mm deep — plan for this footprint when laying out a multi-starter panel section. The reversing configuration means two contactor-style power paths in one housing, so adjacent cable ducting needs to accommodate both sets of power wiring. Operating ambient temperature range of -25 to +50 °C covers most unconditioned industrial enclosures; no derating needed at the lower end, but verify airflow if the panel runs near the 50 °C ceiling with multiple starters ganged.","metaTitle":"Siemens 3RK4320-5JQ61-1BA2 SIRIUS Motor Starter, CLASS 10","metaDescription":"Siemens SIRIUS 3RK4320-5JQ61-1BA2 reversing motor starter with solid-state protection, CLASS 10 trip, 4 A at AC-3 400 V, AS-Interface.
