Siemens designed the 6RA7078-6FV62-0 within the SIMOREG series as a DC master commutation protector that includes a microprocessor. This component is essential for the management of precise control in DC applications. It operates efficiently within a supply frequency of 50 to 60 Hertz.

The device is capable of sustaining ambient temperatures ranging from 0°C to 55°C, provided the environment remains non-condensing. Additionally, it can manage storage conditions with a temperature fluctuation from -25°C to 70°C without condensation effects, ensuring robust performance and reliability during harsher storage conditions.

Powering up the unit, the rated supply voltage can vary between 380 to 460 Volts AC, and it is configured for a three-phase network type. In operation, it accepts a DC voltage rating of 480 volts, along with an output voltage rating of 500 volts DC.

The device can handle a rated input current of 233 Amperes and a maximum DC current of 280 Amperes, which aligns with its power capabilities. Rated at 118 kilowatts, the unit effectively delivers considerable electrical power. Weighing in at 37.49 pounds (17 kilograms), this commutation protector can be installed at altitudes below 2,000 meters (or about 6,561.68 feet) above sea level, satisfying varying installation needs.

Additionally, this product features a pollution degree rating of degree 2, indicating its suitability for industrial applications that may encounter some environmental contaminants but are still reasonably clean.
