LMK8 ( BH ) -0.66 type current transformer is mainly used for indoor, for rated voltage of 0.66 kV and below, rated frequency of 50 Hz AC circuit as current, electric energy measurement or measurement protection.

Meet the standard : GB / T 20840.2

    Model and its meaning

    Normal working conditions and installation conditions

    ■Installation location: Indoor installation only, outdoor installation is prohibited.

    ■Temperature conditions: The ambient operating temperature needs to be controlled between -5℃ and 40℃ to ensure stable operation of the equipment.

    ■Humidity standard: The monthly average relative humidity shall not exceed 90% to avoid the impact of high humidity on the equipment.

    ■Altitude limitation: The altitude of the installation site should be ≤1000 meters. Exceeding this range may affect the performance of the equipment.

    ■Atmospheric environment: The atmosphere must be kept clean, free from obvious pollutants such as dust, smoke, corrosive gases, vapors, and salt spray.

    Scope of application

    This product is a high-performance plastic shell current transformer, specifically designed for integration into complete sets of electrical cabinets. Thanks to its compact structure and reliable operational performance, it has been widely adopted in various low-voltage and medium-voltage cabinet systems, playing a crucial role in current measurement and protection within power distribution networks.

    In terms of installation flexibility, the transformer supports two practical fixing methods: busbar mounting and base plate fastening. This dual-installation design allows it to be seamlessly installed in either horizontal or vertical orientations, adapting to different spatial layouts and wiring requirements of complete cabinets without the need for complex adjustments.

    Compared with the traditional Type I and Type II current transformers, this plastic shell model boasts distinct competitive advantages. It features a larger current-carrying capacity, enabling it to meet the demands of high-power electrical systems while maintaining stable performance. Additionally, it delivers higher measurement precision, ensuring accurate data feedback for power monitoring and control. Moreover, the product adopts an integrated structural design, resulting in fewer auxiliary accessories, simplified assembly procedures, and significantly improved installation efficiency—greatly reducing the workload of on-site construction and maintenance.
