Siemens 3UF7101-1AA00-0 Specs: SIMOCODE pro Current Measuring Module Guide

The Siemens 3UF7101-1AA00-0 is a SIMOCODE pro current measuring module with a 2.4–25 A current setting range, a 45 mm overall width, and a straight-through transformer design. It measures three-phase motor current and connects to a compatible SIMOCODE basic unit. Its key limitation is that it does not measure voltage, active power, energy, or frequency, so engineers should confirm that the required monitoring functions are supported by the complete system.

Siemens 3UF7101-1AA00-0 Specifications

The module is designed for motor management applications in which current measurement is required as part of a SIMOCODE pro configuration. The following specifications are listed in Siemens product documentation.

Sources: Siemens Industry Mall product information and the official Siemens technical datasheet. Confirm the latest documentation before installation or replacement.

How Does the 3UF7101-1AA00-0 Work?

The module measures motor current through its straight-through transformer arrangement. The three phases of the main circuit pass through the designated openings, allowing the module to provide current measurement data to the connected SIMOCODE system.

This data supports motor monitoring and protection functions managed by the compatible SIMOCODE basic unit. The measuring module is not a standalone motor controller; its operation depends on the correct system connection and configuration.

During installation, phase assignment and conductor routing must follow Siemens instructions. Incorrect phase routing or an incompatible system configuration can affect measurement and system operation.

Is the 2.4–25 A Range Suitable for Your Motor?

The current range is the first parameter to check when selecting the 3UF7101-1AA00-0. The intended motor application’s current requirements must fit the module’s specified range and the requirements of the complete SIMOCODE configuration.

• Below 2.4 A: Evaluate a lower-range module if the application falls outside this model’s specified range.
• Within 2.4–25 A: Check the motor’s rated current, operating conditions, and required protection functions against the system configuration.
• Above 25 A: Consider a higher-range measuring module with suitable electrical and installation characteristics.

The current setting range should not be confused with the motor’s permissible operating current under every condition. Correct motor protection also depends on the basic unit, configured protection functions, motor data, and applicable installation requirements.

3UF7101-1AA00-0 vs Other SIMOCODE Current Measuring Modules

Siemens offers different measuring modules for different current ranges and connection arrangements. Choosing a model based only on its product family can lead to an unsuitable measurement range or physical connection.

These models have different current ranges, so they should not be treated as interchangeable. Before choosing an alternative, verify the current requirements, feed-through dimensions, basic-unit compatibility, and installation instructions in the Siemens SIMOCODE pro system manual.

What to Check Before Replacing the Module

For maintenance and replacement projects, matching the full order number is the safest starting point. The following checks help prevent selection errors.

1. Verify the current range: Confirm that 2.4–25 A matches the intended application.
2. Check the basic unit: Confirm compatibility with the existing SIMOCODE pro system generation and configuration.
3. Inspect conductor dimensions: Verify that the conductors fit the 7.5 mm feed-through openings and comply with installation requirements.
4. Confirm measurement requirements: This module measures current, not voltage, active power, energy, or frequency.
5. Review the installation: Check phase routing, mounting, wiring, and the manufacturer’s commissioning instructions.

Frequently Asked Questions

What is the current range of the Siemens 3UF7101-1AA00-0?

Its specified current setting range is 2.4–25 A. The correct selection depends on the motor application and the requirements of the complete SIMOCODE system.

Does the 3UF7101-1AA00-0 measure voltage or power?

No. Siemens specifies current measurement but not voltage, active power, energy, or frequency measurement for this module.

Can the 3UF7101-1AA00-0 operate independently?

No. It is a measuring component intended to connect to a compatible SIMOCODE basic unit rather than operate as an independent motor management controller.

What is the difference between the 3UF7100 and 3UF7101?

The 3UF7100-1AA00-0 covers 0.3–3 A, while the 3UF7101-1AA00-0 covers 2.4–25 A. The correct model depends on the required current range and system configuration.

Conclusion

The Siemens 3UF7101-1AA00-0 is a 45 mm SIMOCODE pro current measuring module designed for a 2.4–25 A current setting range. Its straight-through transformer design and 7.5 mm feed-through openings make physical compatibility important during replacement. Verify the current range, basic-unit compatibility, conductor dimensions, and required measurement functions against Siemens documentation before selecting the module.
