Product Description
The motor protection device SIPROTEC 7SK85 is part of the SIPROTEC 5 series of modular field devices.
This device is designed for the protection of all motor sizes. With its flexibility and its high-performance DIGSI 5 engineering tool, the SIPROTEC 7SK85 fits perfectly for protection, control, monitoring, and measuring applications in electrical energy systems.
Main function:Motor protection for all motor sizes
Inputs and outputs:
- 3 predefined standard variants with 4 current
- transformers, 4 voltage transformers,
- 11 to 27 binary inputs, 9 to 17 binary outputs
Hardware flexibility:Flexibly adaptable and expandable I/O quantity structure within the scope of the modular SIPROTEC 5 building block, 1/6 expansion modules can be added. Available with large or small display or without display
Width of housing:1/3 x 19'' to 2/1 x 19''
All functions can be configured freely with DIGSI 5. For the application of some of the functions, you require the appropriate number of free function points within the device. The function point calculator in the online configurator provides support in determining the required number of function points for your device.
