Powtran PR5300 022G3N 22 kW / 380–440 V 3-Phase Soft Starter — Intelligent On-Line Bypass Control

Detailed Description

The PR5300 022G3N is an intelligent on-line soft starter rated at 22 kW, designed for three-phase motors operating on 380-440 V AC. It features an integrated bypass contactor, advanced motor control, and full protection capabilities—ideal for smooth motor starts and stops in industrial applications.

Key Features & Benefits

• Soft start / soft stop control to reduce inrush current, mechanical stress, and voltage dips

• Integrated bypass contactor that transitions the motor to full voltage after startup, improving efficiency

• Multiple starting modes: current limit, voltage ramp, “kickstart”, dual-loop control, etc. 

• Protection functions: over/under voltage, phase loss, phase imbalance, overcurrent, short circuit, overheating, motor stall, etc. 

• RS-485 communication (Modbus RTU) for remote monitoring and control 

• Human-machine interface: LCD + keypad for local configuration and status monitoring 

• Forced air cooling, compact design, and reliability for industrial use 

Technical Specifications (Highlights)

• Rated power: 22 kW 

• Max current (approx): ~ 45 A 

• Input / output voltage: 380 V to 440 V (3-phase) 

• Mounting & environment: for indoor use, ambient temperature typically –10 °C to +40 °C, humidity < 90% (non-condensing) 

• Communication protocol: Modbus RTU over RS-485 

Applications

Suitable for use in:

• Pumps, fans, compressors

• Conveyor systems

• Industrial machinery needing controlled starts

• Systems where reducing electrical grid stress or mechanical wear is critical
