Features:
- Integrated current measurement feeds the motor protection model.
- Four inputs and four relay outputs implement feeder control logic.
- PROFIBUS DP exchanges commands, status, and diagnostic records.
Siemens 3UF5011-3AN00-1 combines protection, control, and communication in one SIMOCODE DP basic unit.
Its current transformer and thermistor input supervise electrical load and motor temperature through separate sensing paths.
Configured inputs drive the control function, while monostable relays switch the assigned contactor or signal circuits.
The Siemens 3UF5011-3AN00-1 code identifies the 230 V AC, 6.3–25 A SIMOCODE DP basic unit with monostable outputs.

Motor Current Measurement
- Range: The integrated transformer measures feeders from 6.3 to 25 A.
- Protection model: Measured current feeds overload and phase monitoring.
- Asymmetry: Phase imbalance is evaluated with the current-dependent functions.
- Trip class: The configured trip class determines the thermal response curve.
Local Control Connections
- Inputs: Four points accept control, reset, and interlock signals.
- Outputs: Four monostable relays operate assigned contactor or alarm circuits.
- Supply: The basic unit uses the documented 230 V AC control supply.
- Testing: The front Test/Reset control supports local status checks and reset.
Bus and Service Interfaces
- Fieldbus: The 9-pin RS485 connector links the unit to PROFIBUS DP.
- Rate: Communication supports rates up to 1.5 Mbit/s.
- Cyclic data: Commands and feeder status pass through the configured DP telegram.
- Service port: The RS232 system interface is separate from the fieldbus connection.
Protection Response Chain
- Overload: The thermal model converts measured current into trip timing.
- Phase fault: Phase failure and asymmetry create distinct diagnostic conditions.
- Temperature: A thermistor input can supervise motor winding temperature.
- Output action: The configured function removes the contactor command when a trip condition is reached.
