Powtran PR5300 045G3N 45 kW / 380–440 V 3-Phase Intelligent Soft Starter with Integrated Bypass

Detailed Description

The Powtran PR5300 045G3N is a robust three-phase intelligent soft starter rated at 45 kW, designed for motors operating within the 380–440 V AC voltage range. It features an integrated bypass contactor, full motor protection, versatile starting modes, and network connectivity—well suited for industrial motor control applications.

Key Features & Benefits

• Soft start & soft stop to reduce inrush currents, minimize mechanical stress, and smooth acceleration & deceleration

• Integrated bypass contactor transitions the motor to full-voltage operation after the soft-start phase, enhancing efficiency

• Multiple starting modes (voltage ramp, current limit, kickstart, dual-loop control, etc.) to adapt to diverse load conditions 

• Comprehensive protection suite: overvoltage, undervoltage, phase loss, phase imbalance, overcurrent, short circuit, stall, overheating, etc

• RS-485 / Modbus RTU communication for remote control, monitoring, and integration into automation systems 

• User-friendly LCD + keypad interface with multiple languages and parameter setting capability 

• Compact, rugged build with forced-air cooling for industrial environments 

Technical Highlights & Specifications

• Rated power: 45 kW (per nameplate, G3N version) 

• Rated current (approx): ~ 90 A (for 45 kW in 3-phase 380-440 V range) 

• Input / output voltage: 380 V to 440 V AC, three-phase

• Support for standard soft starter parameters, protections, and communication per PR5300 series design Ambient conditions: typically –10 °C to +40 °C (depending on installation and manufacturer recommendations) 

• Matching with motors: intended for cage-type three-phase asynchronous motors, motor’s rated current should match or be below soft starter capacity 

Applications

This soft starter is ideal for:

• Large pumps, compressors, fans, and blowers

• Heavy machinery and equipment with high starting loads

• Conveyors, crushers, or industrial systems requiring soft starts & stops

• Systems needing remote monitoring or integration into SCADA/PLC via Modbus

• Environments requiring high protection and reliable con
