By certification 
 Acrel measuring current transformer has a primary current measurement range of 5-3000A, the accuracy level of 0.2 class or 0.5 class, transform high current value to 5A or 1 A, dedicated to industrial measurement, and can be used in conjunction with a billing electric energy meter, and the measurement is accurate and reliable. |

Our Current Measuring Transformer used a flip design, beautiful appearance and convenient wiring. Flip cover material selected transparent polycarbonate can see the wiring of the secondary lead clearly. The circular combination hole type can be used as an AC current signal to pass through the cable and bus bar setting components and is usually used in combination with electrical measuring instruments.
