SSW07​

​The three-phase voltage control on the WEG SSW07 soft-starter allows its use in applications considered heavy, such as alternate, centrifugal pumps, fans, exhausters, blowers, air compressors, refrigeration, mixers, aerators, centrifuges, rock crushers, grinders, woodchippers, paper refiners, rotary ovens, wood saws and planes, ball and hammer mills and load conveyors.

Characteristics:

• Currents: 17 to 412 A/ Voltage: 220 to 575 V
• High starting duty
• 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 reduced weights and dimensions
• Profibus DP, DeviceNet, RS232 and RS485 communication (optional)

Benefits:

• Elimination of mechanical shocks 
• 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 (gear boxes, pulleys, gears, belts, etc.) during the start
• Prevention of water hammer in pumps
• Built-in electronic thermal relay
• Easy to operate, adjust and service
