ABB's product [1TNA920633R2002](https://www.cwlyautomation.com/product/4686.html "1TNA920633R2002") is a motor protector. Recently many customers required about this product set and bought from CW Green Tech Company. ### Product composition - **M102-M**: It is a motor control unit and belongs to the M10X series. The main unit consists of the electronic components of the motor control unit and the integrated CT. The integrated CT ranges from 0.24A to 63A. For motor ratings greater than 63A, a plug-in CT can be selected. - **MD21 operation panel**: Used with M102-M, it is convenient for users to set parameters, view operating status, and other operations. - **TA201 CBL 1TNA911005R2101**: It may be a matching connection cable or related accessories for electrical connection or signal transmission between components. ### Functional features of [1TNA920633R2002](https://www.cwlyautomation.com/product/4686.html "1TNA920633R2002") - **Control and protection function** - **Control function**: It can control basic operating operations such as starting, stopping, forward and reverse rotation of the motor, and may also have some advanced control functions, such as soft start, speed regulation, and other functions. - **Protection function**: It can realize various protection functions such as overload, phase failure, three-phase imbalance, stall, underload, no-load, grounding, motor thermal protection, etc. - **Measurement and display function**: It can measure and display the actual current value of three phases, the percentage current of three phases (actual current/rated current), current imbalance and other parameters in real time, so that users can understand the operation status of the motor. - **Data recording function**: It provides 256 SOE (sequence of events) with timestamps, which can record key events and fault information during the operation of the motor, which is helpful for fault analysis and equipment maintenance. - **Communication function**: It generally has a communication interface, such as RS485, etc., and can support communication protocols such as Modbus, which is convenient for communication with the host computer or other devices to realize remote monitoring and management. ### Electrical parameters of 1TNA920633R2002 - **Rated voltage**: The marked voltage level is 220VAC, but in fact this series of products usually supports 24VDC, 110VAC and 240VAC. - **Current specification**: The built-in CT range is 0.24~63A, which can meet the protection needs of most small and medium-power motors. When the motor current is greater than 63A, the measurement range can be expanded by connecting an external current transformer. ### Application scenarios of 1TNA920633R2002 **Industrial field:** Widely used for motor protection in various industrial production equipment, such as in the chemical, metallurgical, electric power, machinery manufacturing and other industries, to protect the motors of driving pumps, fans, compressors, conveyor belts and other equipment, to ensure the stable operation of these key equipment and reduce production interruptions caused by motor failures. **Commercial buildings:** In the air-conditioning system, ventilation system, water supply and drainage system, etc. of commercial buildings, it is used to protect the corresponding motors to ensure the comfortable environment and normal operation of equipment in the building. Infrastructure: In infrastructure projects such as urban water supply, sewage treatment, rail transit, etc., it can provide protection for related motors, ensure the reliable operation of infrastructure, and provide support for the normal operation of the city. ### Mechanical characteristics of [1TNA920633R2002](https://www.cwlyautomation.com/product/4686.html "1TNA920633R2002") - **Installation method**: The host is designed with a mounting rail for easy DIN rail installation. Screw mounting accessories are also provided when installed vertically to ensure a firm and stable installation. - **Size**: The overall size is reasonably designed to minimize the footprint while meeting the functions, making it easy to install and layout in various electrical control cabinets.
