The Siemens SENTRON PAC3220 7KM3220-0BA01-1DA0 is a power monitoring device and control-panel instrument designed for comprehensive monitoring of electrical variables in industrial and commercial power systems. It features a 96 × 96 mm graphical LCD display, Modbus TCP communication, True RMS voltage and current measurement, and supports x/1 A or x/5 A CT inputs. The specified rated measurement voltage is 690/400 V, with a measurable line frequency of 45–65 Hz. Siemens' current data sheet identifies the article as an active SENTRON PAC3220 measuring device.
The 7KM3220-0BA01-1DA0 belongs to the Siemens SENTRON PAC3220 family of power monitoring devices. It is designed to measure and display important electrical quantities while also providing Ethernet-based communication for integration with higher-level monitoring and automation systems.
The device is suitable for electrical distribution panels, PCC and MCC panels, feeder monitoring, industrial plants, building power systems and energy-management applications. Siemens specifies the unit for stationary panel installation in closed rooms.
The PAC3220 uses a graphical LCD display designed for clear local visualization of electrical measurements.
The display area is approximately 54 mm high × 72 mm wide, with a white display background. This gives operators direct access to measurement information at the panel without requiring a separate PC or SCADA screen.
The graphical interface is useful during:
Commissioning
Routine inspection
Electrical troubleshooting
Load monitoring
Maintenance
System verification
A major feature of the 7KM3220-0BA01-1DA0 is its Modbus TCP communication capability.
This allows the PAC3220 to communicate through an Ethernet network with compatible:
PLC systems
SCADA systems
HMI systems
Energy-management systems
Industrial monitoring platforms
Building-management systems
The Ethernet-based communication makes it suitable for centralized electrical monitoring and energy-data collection.
The PAC3220 uses True RMS measurement for both voltage and current. Siemens specifies measurement of complete voltage curves and supports both sinusoidal and distorted waveforms. Automatic frequency detection is available across the 45–65 Hz range.
True RMS measurement is particularly useful in industrial installations containing:
Variable-frequency drives
Rectifiers
UPS systems
Power converters
Switching power supplies
Nonlinear loads
The exact article is specified with a 690/400 V rated measurement voltage.
This makes the PAC3220 suitable for higher-rated low-voltage distribution systems where conventional 400 V-class measurement is required.
The actual voltage connections must be configured according to the electrical network and Siemens installation requirements.
The 7KM3220-0BA01-1DA0 supports x/1 A or x/5 A current-transformer secondary inputs.
This allows the meter to work with commonly used industrial CTs for:
Main incomers
Feeders
Generator outputs
Motor feeders
Distribution sections
Industrial equipment
Correct CT ratio configuration is essential for accurate current, power and energy readings.
The PAC3220 is designed for measurement of a wide range of electrical variables.
Depending on the configured network, the device can measure:
Voltage
Current
Active power
Reactive power
Frequency
Power factor
Energy
Other relevant electrical quantities
Siemens specifically confirms voltage, current, active power, reactive power and frequency measurement for this article.
This multifunction capability allows several electrical monitoring functions to be combined in a single panel instrument.
The PAC3220 measures active power, allowing users to monitor the actual electrical power consumed or supplied by the monitored system.
Active-power monitoring can support:
Feeder analysis
Load monitoring
Generator monitoring
Production-line energy analysis
Energy-management applications
The device also provides reactive power measurement, which is useful for understanding the behavior of inductive and other reactive loads.
Reactive-power information can be used alongside active power and power factor to evaluate the operating condition of an electrical network.
The PAC3220 supports frequency measurement over the documented 45–65 Hz range.
Automatic line-frequency detection makes it suitable for standard 50 Hz and 60 Hz electrical systems without requiring manual frequency selection.
The PAC3220 is designed for broader electrical monitoring beyond voltage and current.
It can be used to monitor parameters such as power factor and energy, making it suitable for:
Energy-consumption analysis
Electrical load assessment
Feeder monitoring
Power-system performance analysis
Energy-management applications
The SENTRON PAC3220 uses the standard 96 × 96 mm panel format.
The documented panel cut-out is approximately 92 × 92 mm, making it suitable for standard multifunction-meter installations.
This format is commonly used in:
PCC panels
MCC panels
Distribution boards
Generator panels
Industrial switchboards
Electrical control panels
Siemens specifies IP65 protection on the front of the PAC3220. This helps provide protection against dust and water exposure when the device is correctly installed in the panel.
The rear terminal area has a lower protection level and should remain within the protected panel enclosure.
The 7KM3220-0BA01-1DA0 uses a wide-range auxiliary power supply of approximately 100–250 V AC/DC with ±10% tolerance.
This allows flexible integration into industrial control-panel auxiliary supplies.
The use of Modbus TCP allows PAC3220 devices to be connected to an Ethernet network rather than relying only on local panel indication.
A typical application can follow:
Electrical Network → CTs/Voltage Inputs → PAC3220 → Ethernet / Modbus TCP → PLC / SCADA / EMS
This architecture is useful when measurement data from multiple electrical panels needs to be collected centrally.
The PAC3220 can form part of an industrial energy-management system by providing electrical measurement data to supervisory software.
Multiple units can be installed at:
Main incomers
Production feeders
Utility systems
Distribution sections
Individual machines
Generator outputs
This enables electrical consumption and operating parameters to be observed at different points in a facility.
The PAC3220 is especially suitable for monitoring electrical distribution equipment where operators need visibility of voltage, current, power and frequency.
Applications can include:
Main distribution boards
PCC panels
MCC panels
Feeder panels
Generator panels
Industrial switchboards
The device can be used for monitoring generator outputs and utility incomers where detailed electrical information is required.
Current, voltage, power and frequency values can help operators assess loading and operating conditions.
In industrial plants, the PAC3220 can be installed on feeders supplying production equipment.
Monitoring electrical parameters at the machine or production-line level can help identify:
Load changes
Abnormal electrical behavior
High consumption
Changes in production demand
Electrical system issues
The PAC3220 and PAC4220 are both SENTRON PAC power monitoring devices.
The PAC4220 is the more advanced model with features such as a color graphic TFT display, higher measurement accuracy and more extensive power-quality analysis capabilities.
The 7KM3220-0BA01-1DA0 is the PAC3220 model with a 96 × 96 mm graphical LCD display and Modbus TCP communication.
The PAC3220 belongs to the SENTRON PAC family, while products such as the SMART 7KT0307, 7KT0308 and 7KT0310 belong to the SMART 7KT family.
The PAC3220 is particularly suitable for applications requiring:
Ethernet-based Modbus TCP
Panel-mounted graphical display
Higher-rated 690/400 V measurement
Industrial power monitoring
The 7KM3220-0BA01-1DA0 can be used for new installations or as a replacement where the application requires a SENTRON PAC3220 with graphical LCD display and Modbus TCP.
