As the winding coil is protected by metal shielding inside the plastic case, the measurement accuracy will not be affected in magnetic field as strong as 300mT. Therefore, this kind of small current transformer is very suitable for anti-tamper energy meters. The busbar, with Φ6.2mm two holes and 21mm hole distance, is removable, which is very convenient in assembly.
