3.2 Device description
The SIRIUS contactors are components of the SIRIUS modular system and
can therefore offer the typical benefits of SIRIUS when it comes to the
selection of components and the assembly and operation of controllers and
load feeders.
The SIRIUS range of contactors encompasses the following:
• Contactors for switching motors of up to 45 kW/400 V
• Auxiliary contactors with the contact variants 4 NO, 3 NO +1 NC, and 2
NO + 2 NC
• Contactor relays for system-specific cooperation with electronic
controllers
• Contactors for particular applications:
- Contactors with 4 main contacts
- Capacitor switching contactors
- Contactors for switching resistive loads
- Contactors with an extended operating range
- Contactor combinations
Frame sizes
The SIRIUS range of contactors covers everything up to 45 kW in 4 frame
sizes. Each frame size has 3 or 4 standard motor outputs:
