Applications & Use Cases

The ABB PSE105-600-70 soft starter is engineered for demanding industrial automation applications where controlled motor start-up and stopping are critical. Typical use cases include:

• Pump and water management systems requiring smooth pressure build-up
• Fan and HVAC drives where reduced starting torque extends belt and bearing life
• Compressors and refrigeration units requiring soft ramp-up to avoid pressure spikes
• Conveyor and material handling systems sensitive to mechanical shock on start
• Industrial control panels and motor control centres (MCC) in manufacturing plants
