The four digital inputs are wired via M12 plugs, and the main power connects through a HAN Q4/2 plug per ISO 23570. Addressing is done through the M12 connector — no DIP switches on the housing. Supply voltage is 24 VDC nominal, with a permissible range of 20.4 to 28.8 V; the maximum allowable voltage is 31.6 V, minimum 26.5 V — stay within that window to avoid nuisance dropout or damage. ## Physical fit and mounting constraints Dimensions: 159 mm deep, 294 mm wide, 215 mm high. That width is the main panel-space consideration — it is wider than a typical contactor-and-overload combination, so check the gland-plate or sub-panel cutout before committing. The recommended mounting orientation is horizontal, but vertical and flat positions are also allowed. Fastening is by screw fixing. Vibration resistance is 7 mm / 2g; shock resistance is 12g for 11 ms. ## Switching delays and reversing capability ON-delay is 85 ms; OFF-delay is 65 ms. These are built-in — no external timer needed for the reversing interlock. The unit supports reverse starting but not direct-on-line starting, which is consistent with a reversing starter design. On-site operation (local pushbuttons) is not supported — all control is through the AS-Interface network and the four digital inputs. ## Power ratings across voltages Rated motor power: 0.75 kW at 400 V, 750 W at 500 V, 0.7 hp at 460/480 V, 1 hp at 575/600 V. The assignment type is 2 — coordinated Type 2 protection, meaning the starter withstands fault currents without damage to the contactor or overload, per IEC 60947-4-1.","metaTitle":"Siemens 3RK1315-6KS41-1AA3 SIRIUS Reversing Starter, IP65, T","metaDescription":"Siemens SIRIUS 3RK1315-6KS41-1AA3 reversing motor starter.
