3UF7101-1AA00-0

3UF7101-1AA00-0 current detection module is a motor protection circuit breaker in the Siemens SIRIUS 3UF7 series. It is designed for industrial motor control and integrates overload protection, short-circuit protection, and isolation functions. It is suitable for AC three-phase motor systems. The dual protection mechanism of bimetallic strip + electromagnetic tripping has strong anti-interference, high temperature resistance, and impact resistance, and is suitable for various harsh industrial environments.

• The rated current (0.1-25A) is accurately set by the knob. The current flows through the bimetallic strip. Continuous overload causes the metal strip to bend and trigger the mechanical tripping. It is suitable for motors of different powers to avoid false tripping and ensure motor safety.
• Instantaneous response (<10ms) prevents short-circuit current from damaging the motor and line.
• Automatically detect three-phase imbalance, trigger protection when abnormal, and avoid motor burning.

As Siemens SIRIUS The core product of the 3UF7 series, 3UF7101-1AA00-0 current detection module, has the most outstanding advantage of adopting the innovative "basic unit + functional module" and flexible expansion capability. It not only simplifies the installation and maintenance process, but also provides users with highly customized solutions.

• Overload protection: According to the thermal memory function, simulate the heating characteristics of the motor to avoid cumulative overheating caused by frequent start and stop.
• Short circuit protection: electromagnetic instantaneous tripping, breaking capacity up to 100kA, to ensure rapid disconnection of fault current.
• Manual opening/closing: It has the function of isolating switch to ensure electrical isolation safety during maintenance.
• Status indication ：Mechanical fault indication (red trip button) clearly identifies the cause of protection action.

• Avoid dust and corrosive gases in the installation environment, ensure good heat dissipation, and install a protective cover when humidity is >95%.
• The overload current (Ir) needs to refer to the motor nameplate to match the motor rated current.
• Manually trigger the trip once a month, tighten the module, and ensure the flexibility of the mechanism.
• When using PROFIBUS or IO-Link, the address and parameters must be set correctly.
• The communication module and the leakage protection module cannot be installed at the same time. A maximum of 2 expansion modules can be installed at the same time.
• Functional test is required after installation (it is recommended to use Siemens SIRIUS Test Kit)
• Select the corresponding range according to the rated current of the motor (e.g. 11kW motor is about 22A, select 3UF7110-1AA00-0).
• When remote monitoring is required, use 3UF7930 (PROFIBUS) or 3UF7935 (IO-Link). Realize remote monitoring and intelligent diagnosis.
• In high short-circuit risk situations (such as the incoming line end of the distribution cabinet), it is necessary to confirm that Icu≥the expected short-circuit current on site.

The modular design of 3UF7101-1AA00-0 enables the Siemens current verification module to successfully realize the transformation from "single protection device" to "intelligent motor management system", which perfectly meets the requirements of equipment flexibility and digitalization in the era of Industry 4.0. Precise protection, modular expansion, and high reliability make it the best product for industrial motor protection.
