Soft starters lower energy use and reduce wear and tear on motors and connected mechanical equipment. Stellar SR22 and WEG SSW05 series compact solid-state soft starters use thyristors for controlled reduced voltage motor starting and stopping. These units then switch to internal contacts for efficient running at the rated speed.
The WEG SSW05 Soft Starter is a compact, fully digital soft starter with a state-of-the-art DSP (Digital Signal Processor) controller. Its digital construction provides optimum operation, diagnostics capability and full motor protection.

SR22 semi-conductor solid state soft starters provide many advantages when used instead of electro-mechanical contactors to control 3-phase AC induction motors:

General purpose soft start motor control applications where traditional across-the-line starting or wye-delta starting would typically be appropriate. Typical application types include:
