The SSW08 soft-starter is a static starter, designed for the acceleration, deceleration and protection of three-phase induction motors by controlling the voltage applied to the motor. Compact, it contributes to optimizing spaces in electric panels and it has all the protections for the electric motor, adapting to the application requirements through optional accessories, which can be easily installed on the soft-starter.

Features

  • Currents: 17 to 412 A
  • Voltage: 220 to 575 V
  • Built-in bypass
  • High starting duty
  • Total control on the three phases
  • Protection of the motor and built-in starter
  • “Kick-Start” function for starting loads with high static friction
  • Remote or local HMI (optional)
  • Input for the motor PTC (optional)
  • Operation in environments up to 55°C
  • Extremely reduces weights and dimensions
  • Profibus DP, DeviceNet, RS232 and RS485 communications (optional)

Benefits

  • Elimination of mechanical shocks
  • Full electronic motor protection
  • Longer lifespan of the motor and equipment
  • Limitation of voltage drops at the start
  • Built-in bypass, providing size reduction and energy savings
  • Great reduction of the stresses on the couplings and driving devices during the start
  • Operation in environments up to 55°C (without current derating for all models)
  • Prevention of water hammer in pumps
  • Built-in electronic thermal relay
  • Kick Start function to start loads with high static friction
  • Easy to operate, adjust and service
  • Monitoring of the voltage of the electronics, allowing backups of the values i x t
  • Simple electrical installation
  • Switched electronics power supply with EMC filter (110 to 240 VAC)

Applications
Reciprocating, centrifugal pumps (sanitation, irrigation and oil), fans, exhausters, blowers, air compressors, refrigeration, misers, aerators, centrifuges, rock crushers, grinders, woodchippers, paper refiners, rotary ovens, wood saws and planes, ball and hammer mills and load conveyors.
