Siemens SIRIUS Innovation 3-Pole Contactor, 37 kW, 80A – 3RT2 Series – 3RT2038-1NB30
Use this high-performance contactor from Siemens’ SIRIUS Innovation range to control heavy-duty industrial loads. The electromechanical device is powered at a lower level than the circuit it controls for optimal energy efficiency. It’s designed for heavy-duty applications and delivers up to 37kW of power. With a mechanical service life of 10 million switching cycles, you can depend on this unit for long-term performance, even with regular use. It comes with integrated fuses that protect against short circuits for improved electrical safety. This makes it a reliable option for controlling lighting and heating circuits.
• Rated surge voltage of 6kV to handle sudden spikes to ensure electrical safety
• Standard DIN rail mounting saves time and effort
• Compact dimensions of 55 (length) x 113.4 (width) x 130mm (depth) for space efficiency in small enclosures
• IP20 (ingress protection) rating indicates resistance to dust and objects larger than 12mm in size
What’s the rated power loss of this contactor?
This contactor has a low power-loss rating of 5.7W. This makes it an energy-efficient choice for your setup.
