Overview
SIRIUS 3RA8 Intelligent Load Feeders
The SIRIUS 3RA8 Intelligent Load Feeders are versatile motor starters designed to enhance automation systems by combining protection, control, and communication in a compact package.
They are ideal for applications requiring real-time monitoring, energy efficiency, and predictive maintenance, making them an excellent choice for modern industrial environments.
Part of the automation
As part of the leading automation concept Totally Integrated Automation (TIA) from Siemens, the SIRIUS 3RC7 Intelligent Link Modules are seamlessly integrated into the existing automation environment.
Transparency down to the field level
Acquire measured values directly and evaluate current status information – for example, in order to determine maintenance requirements ahead of time. Thanks to integrated diagnostics, you can detect and correct errors more quickly.
Proactive protection
The integrated overload function and the detection of errors, deviations, and maintenance requirements make diagnosis easier and enable preventive maintenance.
Minimal effort
Thanks to a significant reduction in wiring effort, easy installation in the control cabinet, and parametrization in TIA Portal, you save time during commissioning and expansions.
