Product Description

TOPRO hinged split-core current transformers KF series offer an excellent balance between function and accuracy. The quick release button makes the CT to fit with conductors(Cable/Wire)for precision current measurement easily, without cutting off the circuit. KF current transformer has advantages of bigger capacity and bigger mounting hole size, so they could be used in many power applications. The installer-friendly design ensures rapid installation in any environment.
