Siemens 3RW52 480V AC 250 kW 3 Phase Soft Starter Model 3RW5244-6AC04

Siemens 3RW5244-6AC04 is a General Performance SIRIUS 3RW52 Soft Starter designed for soft starting and stopping of three-phase asynchronous motors up to 250 kW at 480V AC. It is ideal for industrial, manufacturing, HVAC, and automation control applications where smooth motor startup and reduced mechanical and electrical stress are required.

This model supports 3-phase control to ensure optimal motor starting torque and current limitation, minimizing voltage dips and mechanical wear on motor components. Its integrated bypass relay reduces heat dissipation and improves energy efficiency within the control cabinet.

Constructed with a screw fixing mount and rated IP00, the Soft Starter offers reliable operation in protected environments. Intelligent monitoring prevents motor overload and overheating, while an integrated remote reset allows quick fault clearance. It also features analog output for status feedback and flexible communication options through optional plug-in modules, including PROFINET, PROFIBUS, and Modbus TCP.

Certified under IEC 60721, IEC 60529, CE, UL, CSA, and CCC standards, the device meets international safety and performance requirements. Dimensions are compact at 210 mm length, 202.5 mm width, and 388 mm depth, ensuring ease of installation in control panels and automation systems.

Key benefits include energy savings through an intelligent Soft Torque function and maintenance-free switching, making it suitable for industrial, manufacturing, commercial, and HVAC motor control applications.
