SIRIUS compact starters are engineered for applications where panel space is at a premium. These motor starters integrate a contactor, overload relay, and control functions into a single, ultra-compact device with a width of just 22.5 mm. Depending on the configuration, they can reduce the required installation volume by up to 75% compared to conventional setups using separate contactors and thermal overload relays. The SIRIUS series supports rated operational currents up to 32 A (AC-3) and voltages up to 690 V, with integrated communication capabilities for PROFIBUS, PROFINET, or AS-Interface. The compact design eliminates the need for extensive point-to-point wiring, as all power and control connections are pre-configured within the housing.
These starters are ideal for installation in distribution cabinets, control panels, and automation enclosures where space constraints are critical. They are widely used in conveyor systems, pump stations, fan controls, and packaging machinery. The SIRIUS compact starter is particularly suited for industries such as automotive manufacturing, food and beverage processing, and material handling, where reliable motor starting and protection are required in high-density layouts. The devices are rated for ambient temperatures from -25°C to +60°C and offer IP20 protection for safe use in enclosed environments.
The main subcategories within the SIRIUS compact starter range include the 3RA6 series for standard applications and the 3RA7 series for safety-related functions. Key article codes follow the pattern 3RA6xxx-xxxxx or 3RA7xxx-xxxxx, where the first digits indicate the series and the following digits specify the rated current, control voltage, and communication interface. For example, the 3RA6110-1CB24-1BB4 is a compact starter for 0.1 A with 24 V DC control and PROFIBUS connectivity. Other common codes include the 3RA6120-1CB24-1BB4 for 0.2 A and the 3RA6130-1CB24-1BB4 for 0.3 A.
