WEG SSW060604T2257PSZ

The SSW060604T2257PSZ is a high-current soft starter from WEG SSW06 series, rated at 604A and compatible with 690V three-phase industrial motor circuits. This SSW060604T2257PSZ adopts thyristor voltage regulation technology to deliver smooth ramp-up and ramp-down for induction motors, reducing starting inrush current and mechanical impact on coupled equipment. The SSW060604T2257PSZ supports standard three-wire connection and inside-delta wiring schemes, giving system designers flexible layout options inside control cabinets.

This SSW060604T2257PSZ integrates a built-in bypass contactor, which cuts power loss and heat generation after the motor reaches full speed. The SSW060604T2257PSZ comes with a removable dual-display HMI, supporting parameter backup, cloning and multi-language operation for fast commissioning. It is equipped with comprehensive protection functions including motor overload, phase loss, voltage imbalance and SCR over-temperature protection, securing continuous operation for heavy industrial loads. The SSW060604T2257PSZ supports Modbus RTU and optional fieldbus modules to connect with PLC and SCADA systems.

The SSW060604T2257PSZ is widely deployed for pumps, fans, compressors and conveyors in mining, water treatment, oil and gas facilities. The pump control function of this SSW060604T2257PSZ effectively suppresses water hammer and protects pipeline systems. The SSW06 platform is a legacy soft starter range, and original factory production of the SSW060604T2257PSZ has been discontinued. Most available units are surplus or refurbished spare parts used for on-site replacement and retrofit of existing motor control panels.
