Bar primary metering CTs selected for low ratio error across the working burden.
Made to your specification
Class 0.2 units and extended burden ranges are available where the metering standard requires them.
The SA metering series is built where the reading matters more than the enclosure. Cores are selected for low ratio error and phase displacement across the working burden, and each unit is checked for ratio and polarity before dispatch.
A solid bar primary removes the variability that comes from how a cable is threaded, which keeps performance consistent from one installation to the next.
