KCT-816 4000A Split Core Current Transformer
The KCT-816 4000A split core current transformer is designed for current measurement on large cables and busbars. It provides a standard 1A or 5A secondary output, Class 0.5 accuracy and a 20VA rated burden.
Its openable core allows installation around an existing conductor without removing the cable or busbar, helping reduce installation time and cost. The 80 × 160mm rectangular window is suitable for switchboards, distribution panels and industrial power monitoring systems.
