SOF T-STARTER Soft-starters are devices dedicated to the smooth acceleration and deceleration of three-phase induction motors by controlling the voltage applied to it. Combining convenience and innovation, the SSW900 is the right choice for a complete motor protection and start/stop control. Developed for industrial or professional use, the new line of soft-starters allows simple and quick access to application information and configuration settings. Using a well structured menu interface, the SSW900 line presents an unprecedented experience of interactivity with the user, allowing...

Main Features Forward / Reverse Fire mode (emergency start) Allows starting and stopping the motor in emergency situations, even when any fault occurs, disregarding the SSW or motor protections. Used to drive hydraulic pumps for firefighting systems. High performance graphic HMI Indication of all variables of the motor or SSW in an easy and intuitive way, using many units and formats, through bar graphs or time graphs. Diagnosis Several status of the SSW are saved at certain moments to facilitate the diagnosis of faults and problems in the application or in the motor. For instance: ■...

Specification The power ratings for the maximum applicable motor shown in the following tables are referential and valid for WEG 4-pole three-phase induction motors under light load conditions (e.g., centrifugal pump). Motor rated power may vary according to the motor data and application. Notes: 1) To select a SSW900 model with control voltage 110-130 V, replace “x" by 3 and to select a model with control voltage 220-240, replace “x" by 4. Models <412 A: AC-53b 3-25:335, ambient temperature of 55 °C; Models >480 A: AC-53b 3-25:695, ambient temperature of 40 °C; Models of 130 A to 200 A:...
