    Feature

    The MR series current transformers offer exceptional flexibility in installation and structural design, providing both base-mounted and baseless mounting options to suit diverse installation environments and fixing requirements. The base-mounted version allows for stable floor or panel mounting, ensuring convenient and precise installation; the baseless version is better suited for space-constrained scenarios or integrated cabinet layouts, meeting varied assembly needs. Furthermore, the product supports configurations with and without terminal covers. The terminal cover design effectively protects internal terminals from dust, moisture, and external forces, enhancing safety; the baseless version facilitates quick wiring and routine maintenance, adapting to operational needs under different conditions.

    As a product series emphasizing high cost-effectiveness, this instrument transformer achieves a low-cost advantage while ensuring basic performance meets standards through optimized manufacturing processes and material selection. It provides an economical and practical solution for budget-sensitive projects or bulk procurement needs. In terms of current adaptation range, the product covers an extremely wide range of rated primary currents, from 5A to 30000A. It can meet the measurement needs of low-current scenarios such as small and medium-sized equipment and civil power distribution, as well as the monitoring and protection of high-current conditions such as large industrial production lines and high-voltage power distribution systems. Its wide applicability and strong practicality make it suitable for a broad range of applications.

    Standard

    IEC60044-1 GB1208-2006

    Scope of application

    The MR series current transformers utilize insulating tape winding as their core technology, making them a low-cost product that combines practicality and economy. The product series is comprehensively planned, including six sub-specifications to meet the basic needs of various current measurement scenarios, providing users with diverse choices.
