Siemens 3RW52 3 Phase Soft Starter 480V AC, 18.5 kW, IP20, Screw Fixing 3RW5215-1TC04

Siemens 3RW5215-1TC04 3 Phase Soft Starter is engineered for reliable soft starting and stopping of three-phase asynchronous motors in industrial and automation applications. Rated at 18.5 kW with a maximum supply voltage of 480V AC, this device reduces mechanical and electrical stress during motor startup.

The soft starter minimizes inrush current peaks, preventing supply voltage fluctuations and reducing load on power networks. Its integrated bypass circuit enables compact installation and energy saving with low heat dissipation within the control cabinet.

Designed for durability, it features screw fixing mount type, IP20 ingress protection, and thermistor motor protection input for intelligent monitoring to prevent motor overload and overheating.

Three-phase controlled operation makes it ideal for higher motor power ratings and delta configurations. The innovative Soft Torque function ensures gentle motor starts.

Additional advantages include a remote reset function allowing quick fault clearing from remote locations, and compatibility with industry communications interfaces such as PROFINET, PROFIBUS, and Modbus TCP via optional plug-in modules. This solves automation integration challenges effectively.

The product originates from the Czech Republic and complies with IEC and UL/CSA approvals, though no specific standards are listed.

Typical industrial use cases encompass manufacturing plants, HVAC systems, water treatment facilities, and general motor control applications demanding energy efficient and space-saving solutions.
