Description

SIRIUS soft starter S2 45 A

The SIRIUS soft starter S2 is designed for the soft starting and ramp-down of three-phase asynchronous motors, ensuring reliable operation and efficiency.

Technical details:

• Rated current: 45 A
• Power: 22 kW/400 V
• Temperature: 40 °C
• Voltage range: 200-480 V AC
• Control voltage: 24 V AC/DC
• Connection type: Screw terminals
• Motor protection: Thermistor
• Approvals: IEC and UL/CSA
• Applications: Hazardous areas (ATEX or IEC Ex)

Customer benefits:

• Soft starting and ramp-down reduce current peaks and prevent supply voltage fluctuations during startup.
• Reduces load on the power supply network and mechanical load in the drive.
• Offers considerable saving of space and wiring compared to star-delta (wye-delta) starters and frequency converters.
• Maintenance-free switching with extremely easy handling.
• Integrated bypass allows for compact construction and low heat dissipation in the control cabinet.
• Intelligent monitoring protects against overheating and overload.
• Current limitation during startup to a settable maximum value.
• Integrated remote reset for easily clearing faults from a remote location.
• Available for supply systems up to 690 V in a wide performance range.
• Optional link module attaches the soft starters to the circuit breakers.
• Optional fan permits even more compact design in the control cabinet.
• Part of the simple and efficient SIRIUS modular system.
