It operates from a 24 V DC supply (20.4... 28.8 V range) and is housed in an IP65-rated enclosure, so it can be mounted directly on the machine frame or in a washdown zone without a separate control cabinet. The screw-fixing fastening method and multiple mounting positions (vertical, horizontal, flat) give flexibility in panel layout. The unit is a direct starter (no reversing) with selectable trip classes 5, 10, 15, and 20, letting you match the overload protection to the motor's start profile. ON-delay is 85 ms; OFF-delay is 65 ms. It accepts 4 digital inputs via an M12 plug for addressing, and the main current circuit connects through a HAN Q4/2 plug per ISO 23570. ## Integration and environmental limits Dimensions: 294 mm wide, 215 mm high, 159 mm deep. Shock resistance is 12g for 11 ms; vibration resistance is 7 mm at 2g. The IP65 protection class allows hose-down cleaning in food, beverage, or chemical processing lines. Communication is via AS-Interface only. There is no PROFIBUS DP or PROFINET protocol onboard. The unit has 4 digital inputs. The M12 plug is used for device addressing.","metaTitle":"Siemens SIRIUS 3RK1325-6KS41-2AA0 Motor Starter, AS-i, IP65,","metaDescription":"Siemens SIRIUS 3RK1325-6KS41-2AA0 motor starter.
