Siemens 3 Phase Soft Starter 480V AC, 45 kW Power Rating 3RW5224-1TC04

Siemens 3RW5224-1TC04 is a 3 Phase Soft Starter designed for industrial automation and motor control applications, capable of operating at a maximum supply voltage of 480V AC and delivering a power rating of 45 kW. This device enables smooth starting and stopping of three-phase asynchronous motors, significantly reducing electrical and mechanical stress.

The soft starter technology minimizes current peaks during startup, preventing disturbances in the supply network and extending motor life. Its compact size and screw fixing mount type facilitate easy installation in control panels with reduced wiring requirements compared to traditional star-delta starters.

Equipped with an integrated bypass, the device ensures low heat dissipation and energy efficiency within the control cabinet. Intelligent thermal monitoring functions protect both the soft starter and the connected motor against overheating and overload conditions, enhancing operational reliability.

Particularly suitable for high power motors and inside-delta circuits, the three-phase controlled soft starter allows precise control over motor torque, aided by the innovative Soft Torque function to ensure gentle motor start-up.

The remote reset feature allows quick fault clearing from remote locations, enhancing maintenance convenience. It supports screw terminals for control voltage supply (24 V AC/DC) and is compatible with various communication modules enabling integration with industrial networks like PROFINET, PROFIBUS, and Modbus TCP.

With worldwide approvals including CSA, IEC, CCC, CE, EAC, UL, and compliance with IEC standards, this soft starter meets stringent industrial requirements. Originating from the Czech Republic, it belongs to the Siemens 3RW52 series known for saving energy and providing compact solutions.
