Built-in electronic overload protection eliminates the separate overload relay, saving a DIN-rail slot and one wiring step. The ramp time is adjustable from 1 to 120 seconds, which covers soft-start profiles from quick pump starts to long conveyor acceleration. Main terminals are IP00 per IEC 60529 and IEC 60947-1 — panel builders need to house it inside a rated enclosure. ## Fieldbus flexibility Communication options cover Modbus-RTU, Modbus-TCP, EtherNet/IP, EtherCAT, DeviceNet, CANopen, PROFIBUS, PROFINET, BACnet-IP, and BACnet-MSTP — the same hardware handles any plant-floor network without swapping a module. Analog outputs are field-configurable for 0-10 V, 0-20 mA, or 4-20 mA, so the starter feeds a drive-signal to a PLC or SCADA without a signal conditioner. Warning and protection functions include current imbalance, locked rotor, earth fault, phase loss, over/under voltage, motor thermal inputs, and user-defined protection. ## Wiring and integration Main circuit terminals accept cable via a clamp with an 8.5 mm hole diameter; tightening torque is 8 N·m. The control circuit connects with rigid 1 x 2.5 mm² wire. A switch for inside-delta connection is built in, which reduces the starter current rating needed for delta-wound motors — a common panel-builder trick to use a smaller frame. Status LEDs on the front panel show running (green), fault (red), and protection (yellow) — enough for a quick walk-by check without opening the cabinet door. Signal relays are provided for run, fault, bypass, and overload, so the starter can annunciate each state to a PLC or a local beacon.","metaTitle":"ABB 1SFA898108R7000 PSTX85 Soft Starter, 208-600 V AC","metaDescription":"ABB PSTX85 soft starter 1SFA898108R7000. 208-600 V AC, built-in electronic overload, auto phase sequence detection, Modbus/EtherNet/IP/PROFINET.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Soft Starters"],"specifications":{"Function":"Auto phase sequence detection","Ramp Time":"1 ... 120 second [unit of time]","Communication":"Modbus-RTU; Modbus-TCP; Ethernet-IP; EtherCAT; DeviceNet; CANopen; Profibus; Profinet; BACnet-IP; BACnet-MSTP","Terminal Type":"Cable Clamp","Analog Outputs":"0...10 V, 0...20 mA, 4...20 mA","Warning Details":"Current imbalance warning; Current underload warning; Electronic overload Time-to-trip; EOL warning; Faulty fan warning; Locked rotor warning; Motor runtime limit warning; Over voltage warning; Phase loss warning (for standby); Power factor underload warning; Short circuit warning (for Limp mode); THD(U) - Total Harmonic Distortion warning; Thyristor overload warning (SCR); Under voltage warning; Voltage imbalance warning","lifecycle_stage":"current","Run Signal Relay":"Yes","Product Main Type":"PSTX85","Tightening Torque":"Main Circuit 8 N·m","Fault Signal Relay":"Yes","Overload Protection":"Built-in electronic overload protection","Protection Function":"Bypass open protection; Current imbalance protection; Current underload protection; Dual overload (separate overload for start and run); Earth fault protection / ground fault protection; Electronic overload protection, EOL; Extension IO failure protection; Fieldbus failure protection; HMI failure protection; Locked rotor protection; Max number of starts/hour; Over voltage protection; Phase reversal protection; Power factor underload protection; PT-100 connection; PTC connection; Too long current limit protection; Too long start time protection; Under voltage protection; User defined protection; Voltage imbalance protection","Rated Frequency (f)":"50/60 Hz","By-pass Signal Relay":"Yes","Degree of Protection":"acc. to IEC 60529, IEC 60947-1, EN 60529 Main Terminals IP00","Overload Signal Relay":"Yes","Current Limit Function":"1.5 ... 7.5 xle","Ambient Air Temperature":"Operation -25 ... +60 °C","Material Compliance/SCIP":"f3a0566c-5aad-4ac9-94d0-4c2d5492623c China","Rated Operational Voltage":"208 ... 600 V AC","Service Factor Percentage":"100 %","Object Classification Code":"Q","Initial Voltage During Start":"10 ... 99 %","Popular Downloads/EPLAN Data":"9AAC181164_EPLAN","Signal Indication Fault (LED)":"Red","Integrated Electronic Overload":"Yes","Step Down Voltage Special Ramp":"100 ... 10 %","Connecting Capacity Main Circuit":"Hole Diameter 8.5 mm","Material Compliance/WEEE Category":"5.
