It's designed to start, stop, and reverse three-phase motors in applications where space is tight and the environment demands washdown or dust protection. The bimetal overload relay provides motor protection against sustained overcurrent. It communicates over AS-Interface (AS-i), the flat-cable fieldbus common in distributed I/O and motor control centers. Power and data share the same yellow AS-i cable, which simplifies wiring in a multi-drop topology. No PROFIBUS or PROFINET onboard — this is strictly an AS-i node. AC-3 covers starting and plugging of squirrel-cage motors — the inrush is higher than the running current, and this contactor is sized for that duty cycle. If your motor nameplate exceeds 4 A FLA at 400 V, step up to the next frame. It's suitable for washdown environments, not submersion. Two digital inputs are built in, each via an M12 socket. They are not parameterizable — they're fixed-function inputs for start/stop or limit-switch signals. No digital outputs on this variant. ## Integration notes The enclosure measures 190 mm deep, 120 mm wide, and 270 mm high. It's not a DIN-rail mount — it's a standalone IP65 enclosure intended for wall or machine mounting. The main energy infeed and load-side outgoing feeder use sockets per ISO 23570, so the mating connectors must be ordered separately if not already in hand. Supply voltage is 24 V DC nominal (20.4 to 28.8 V range, max 31.6 V). The AS-i cable provides both power and communication via the cutting/clamping method — no separate control wiring needed for the bus. A front addressing socket allows configuration without opening the enclosure.","metaTitle":"Siemens 3RK1322-1ES02-1AA0 reversing starter, IP65, 4 A AC-3","metaDescription":"Siemens 3RK1322-1ES02-1AA0 reversing starter, current lifecycle stage, 4 A at AC-3 400 V, IP65, AS-Interface bus communication, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Remote I/O & Fieldbus Modules"],"specifications":{"Depth":"190 mm","Width":"120 mm","at DC":"24 ... 24 V","Height":"270 mm","Type of voltage":"DC","lifecycle_stage":"current","During Operation":"-25 ... +55 °C","Bus communication":"Yes","PROFINET protocol":"No","at DC rated value":"20.4 ... 28.8 V","Type of assignment":"1","Maximum Permissible":"31.6 V","Minimum Permissible":"26.5 V","Protection class IP":"IP65","PROFIBUS DP protocol":"No","at 400 V rated value":"50 000 A","Design of the product":"reversing starter","For Device Addressing":"front addressing socket","For Main Energy Infeed":"socket according to ISO23570","Supply voltage 1 at DC":"30 ... 30 V","Number of digital inputs":"2","Short circuit protection":"Yes","For Digital Input Signals":"1","For Digital Output Signals":"0","brake control with 24 V DC":"No","1 For Digital Input Signals":"M12 socket","2 For Digital Input Signals":"M12 socket","Operating frequency minimum":"1 1/h","brake control with 400 V AC":"No","brake control with 500 V DC":"No","For Main Energy Transmission":"socket according to ISO23570","For Supply Voltage Line-Side":"via AS-I shaped cables with cutting/clamping method","Type of the motor protection":"bimetal","at AC-3 at 400 V rated value":"4 A","For Load-Side Outgoing Feeder":"socket according to ISO23570","Operating voltage rated value":"400 ... 500 V","Digital Inputs Parameterizable":"No","For Communication Transmission":"via AS-I shaped cables with cutting/clamping method","Of The Communication Interface":"via AS-I shaped cables with cutting/clamping method","Design of the switching contact":"electromechanical","Digital Outputs Parameterizable":"No","For Supply Voltage Transmission":"via AS-I shaped cables with cutting/clamping method","Design of short-circuit protection":"circuit-breakers","Product component Motor brake output":"No","Reference code acc. to DIN EN 61346-2":"Q","Reference code acc. to DIN EN 81346-2":"Q","Control supply voltage at DC rated value":"20.4 ... 28.8 V","Number of poles for main current circuit":"3","Protocol is supported AS-Interface protocol":"Yes","Operating power at AC-3 at 400 V rated value":"1.5 kW","Type of voltage of the control supply voltage":"DC","Type of electrical connection for main current circuit":"tab terminals","Adjustable pick-up value current of the current-dependent overload release":"2.8 ... 4 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,153.73","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=535206&mlfb=3RK1322-1ES02-1AA0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RK1322-1ES02-1AA0/alternatives.json"},"ai":{"faq":[{"question":"What are the key ratings for this reversing starter?","answer":"It is rated 4 A at AC-3, 400 V for motor switching, with a 50 kA short-circuit breaking capacity at 400 V.
