Code and implication
Application
The ZHIMING LMK1(BH)-0.66 type current transformer is primarily intended for indoor use in AC circuits with a rated voltage of up to 0.66 kV and a rated frequency of 50 Hz. It is used for current and energy measurement, as well as relay protection.
This model is a plastic-encased current transformer, widely used in low-voltage switchgear assemblies. It supports both busbar and base plate mounting and is suitable for installation in any direction. The primary conductor can be either a busbar or a cable.
