Product Description

The RQ6000-30KW is an online soft starter for 380V three-phase induction motors, rated 60A. Built on power electronics and microprocessor control with SCR-based smooth acceleration and soft-stop functionality, it replaces star-delta and auto-transformer starters — delivering reliable motor control and comprehensive protection, with no external bypass contactor required.

Key Features

3 start modes: Current-limit / Voltage-ramp / Kick-start ramp
2 stop modes: Free stop / Soft stop (prevents water hammer)
Real-time 3-phase current display with independent calibration
Bilingual LCD (Chinese/English), stores last 12 fault records
Dual programmable relay outputs + 4-20mA analog output + RS485 Modbus RTU (standard)
No external bypass contactor needed — simplest wiring among all soft starter types

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
