WEG SSW07 – Soft Starters

Soft-Starters are static starters that accelerate, decelerate and protect three-phase induction motors in power ratings from 4,5 to 315 kW.

Using high technology, WEG soft-starters were designed to ensure the best performance for each application, offering resources that enable to start, stop and protect electric motors in a simple and efficient way.

The SSW07 and SSW08 soft-starters are ideal for the soft start of centrifugal pumps, fans and other applications that require good overload capacity and excellent cost-benefit, as they have advanced control for the three phases of the motor and built-in bypass.

Features

• Reduction of mechanical stresses over the coupling and transmission devices (gearboxes, pulleys, gears, conveyors) during the start

• Increases motor and machine mechanical equipment lifetime due to the reduction of mechanical stress

• Easy operation, setup and maintenance

• Simple electrical installation

• Operates in environments up to 55 °C (without current reduction for all models)

• Integral, electronic motor protection

• Kick-Start function for starting high breakaway torque loads

• Reduces Water Hammer in pump applications

• Limitation of voltage drop during start

• Universal voltage (220 to 575 Vac)

• Switched mode power supply with EMC filter for the control electronics (110 to 240 Vac)

• Built-in by-pass providing size reduction and energy saving

• Voltage monitoring of the electronics allows to back-up I x t values (thermal image)
