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 250 kW/400 V (400 Hp /460 V)
• Vacuum contactors for switching of motors from 110 to 250 kW/400 V
(150 to 400 Hp/460 V)
• Auxiliary contactors with the contact variants 4 NO, 3 NO +1 NC, and
2NO + 2NC
• 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 250 kW(400 Hp) in
7 sizes. Each frame size covers multiple standard motor ratings:
