Product Description

The RQ6000-15KW is an online AC motor soft starter for 380V three-phase induction motors, rated 30A. Built on power electronics and microprocessor control with SCR-based smooth acceleration, it replaces star-delta and auto-transformer starters — delivering integrated protection and reliable motor control, with no external bypass contactor required.

Applications

Pumps & Fans — smooth start reduces water hammer and belt/duct stress
Conveyors — gentle load engagement, less mechanical shock on belts and gearboxes
Compressors — controlled acceleration protects valves and reduces pressure spikes
Crushers & Mixers — handles high starting torque loads with kick-start ramp mode

Selection Tip

Recommended soft starter power = Motor Power × Load Factor (Pump/Fan: 1.2, Conveyor: 1.3, Compressor: 1.5, Crusher/Mixer: 1.6). Not sure which factor applies? Use our Soft Starter Selection Calculator: https://www.softstarterpro.com/blogs/selection-tools/soft-starter-selection-guide
