Need help selecting a soft starter?
Use our selector tool
to configure and order.
Basic solid-state soft starters use thyristors for controlled reduced voltage motor starting/stopping and are designed to fit in place of existing wye-delta starters. Soft starters lower energy use and reduce wear on motors and mechanical equipment.
Basic AC motor soft starters provide for gradual motor starts (and stops, if equipped), reducing the
mechanical shock associated with full on/full off motor control. They also offer additional motor
protections and are capable of handling a variety of applications from standard duty, including
agitators and lathes, to heavy duty, including crushers, shredders, and wood chippers.
