Low voltage current transformers (CTs) are key components used to measure alternating current (AC) in electrical systems for metering, monitoring, and protective relaying. By scaling high currents down to manageable levels for instruments and controllers, CTs enable accurate current sensing without interrupting the circuit. Designed for safety and precision, they are commonly used in switchboards, panelboards, and energy management systems across commercial and industrial settings. Various sizes, mounting options, and accuracy classes are available to match diverse application needs.
