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:...
