It is designed for decentralized motor control on AS-interface networks, with the supply voltage and communication carried through the same AS-i shaped cable via cutting/clamping method. The IP65 rating means the enclosure withstands washdown and dust ingress, making it suitable for food-and-bev lines, packaging machines, or any environment where the starter is mounted directly on the machine frame rather than in a central panel. The motor rating is 4 A at 400 V in AC-3 duty — that is the switching category for squirrel-cage induction motors during starting and plugging. A 4 A AC-3 rating typically covers a 1.5 kW to 2.2 kW motor at 400 V three-phase, depending on the motor's full-load current. The operating voltage range is 400 to 500 V, so it works on 400 V, 415 V, and 480 V line supplies common in European and North American industrial plants. Motor protection is via thermistor (PTC) input — the starter monitors the motor's internal temperature sensor directly, rather than relying on a bimetallic overload relay. This gives better protection against overtemperature in cyclic or high-inertia loads. The two digital inputs (M12 socket, parameterizable) can be used for external pushbuttons, limit switches, or sensor feedback, with the supply voltage for the inputs drawn from the AS-i bus. ## Integration and mounting — what connects where The main energy infeed and the load-side outgoing feeder both use sockets according to ISO 23570, which is the standardized interface for decentralized drive systems. A front addressing socket is provided for setting the AS-i address without opening the enclosure. The supply voltage line-side connection uses AS-i shaped cables with cutting/clamping method — no separate power cable required; the AS-i flat cable carries both 24 V DC power and communication. The same cable method is used for communication transmission and for supply voltage transmission to the digital inputs. The rated supply voltage is 24 V DC (20.4 to 28.8 V range, maximum permissible 31.6 V).","metaTitle":"Siemens 3RK1323-2AS54-1AA0 reversing starter, IP65, 4 A AC-3","metaDescription":"Siemens 3RK1323-2AS54-1AA0 reversing starter, 4 A at 400 V AC-3, IP65, 2 digital inputs via M12, AS-i communication.
