SIRIUS Modular System

The Siemens SIRIUS Modular System is a modular system for circuit protection and switching. The contactors from the system are ideal for switching motors and other electrical consumers. Optimally matched and dimensioned products, available in all sizes, support users in their specific applications. The SIRIUS Modular System provides users with all the devices necessary for switching, protecting, controlling, and monitoring motors, covering frame sizes S00 to S12 (fractional HP to 400 HP at 460 V). The portfolio has over 50,000 combination tests and approvals for worldwide use. Pre-assembled motor starters are offered up to 20 HP at 460 V.

With Siemens SIRIUS 3RC7, the SIRIUS switchgear is transformed into intelligent sensors that provide real-time information and open up new possibilities. Numerous parameters of the load feeder, such as voltage, current, phase asymmetry, and the number of overload tripping events, can be directly recorded and evaluated. The integrated diagnostic functions help detect and correct errors faster. The data can be utilized for predictive maintenance and more.

With SIRIUS 3RC7, the SIRIUS Modular System goes digital. By integrating it into the SIMATIC system via the SIMATIC ET 200SP, the intelligent link module creates a connection between field devices and automation. It enables comprehensive transparency, thereby optimizing performance at all levels.

Features

• The SIRIUS 3RV29 infeed system is a small power bus up to 63 A and can be installed almost without tools thanks to the plug-in connection, perfect for eliminating power feeder wiring and saving space for small motor and circuit breaker applications
• Switching technology is integrated into automation with the Siemens Totally Integrated Automation (TIA) concept
• Easy access to all product documentation through CAx download manager available on the Siemens Industrial Online Support (SIOS) site
• Proactive protection: The integrated overload function and the detection of faults, deviations, and maintenance needs facilitate diagnostics and enable preventive maintenance
• Load feeders in sizes S00 and S0 up to 32 A can be easily connected to the automation system thanks to the intelligent SIRIUS 3RC7 link module, which provides process transparency and control for maximum system availability
