That saves a couple of inches of DIN rail in a crowded panel. The 3-pole main current circuit (Number Of Poles For Main Current Circuit listed as 3) handles the three-phase power legs; the two digital inputs (Number Of Digital Inputs listed as 2) let a PLC or safety relay command forward and reverse directly without an interposing contactor bank. ## Mounting and enclosure — will it survive the route? IP55 protection class (protection class IP listed as IP55) means this starter handles hose-down and dust — suitable for washdown areas on food-and-bev lines or outdoor conveyor galleries. It's not submersible, but it'll shrug off rain, condensation, and the occasional pressure-wash splash. The mounting position allows +/-180° rotation on a vertical surface, plus +/-22.5° tilt forward and backward (Mounting Position listed as +/-180° rotation possible on vertical mounting surface; can be tilted forward and backward by +/- 22.5° on vertical mounting surface). That's useful when you're fitting it into a tight corner of a machine base or a pedestal-mounted enclosure where the cable entry angle matters. Dimensions of 145 mm depth, 182 mm width, and 220 mm height (Depth listed as 145 mm, Width listed as 182 mm, Height listed as 220 mm) put it in the medium-footprint class for reversing starters. Plan for about 8 inches of panel width per unit if you're laying out multiple starters side by side with wiring gutters. ## Supply voltage and control wiring The operating voltage is 340 to 440 V AC (Operating Voltage Rated Value listed as 340... 440 V), which covers the common 400 V three-phase industrial supply. The control supply voltage range is 184 to 253 V at 50 Hz and 196 to 253 V at 60 Hz (at 50 Hz rated value listed as 184... 253 V; at 60 Hz rated value listed as 196... 253 V) — that's a standard 230 V control transformer secondary. No fieldbus onboard (Bus Communication listed as No; PROFINET protocol listed as No; PROFIBUS DP protocol listed as No; protocol is supported AS-Interface protocol listed as No), so this is a hardwired starter. The two digital inputs are the only signal interface; everything else is power wiring.","metaTitle":"Siemens SIRIUS 3RK4353-3JR58-1BA0 Reversing Motor Starter","metaDescription":"Siemens SIRIUS 3RK4353-3JR58-1BA0 reversing motor starter. 4 A at 400 V AC-3, CLASS 10, IP55.
