Current Transformer
The SACT251 series open-type current transformers are designed for current measurement and galvanic isolation on busbars. Their rectangular magnetic circuit and uniformly wound secondary windings provide a compact, practical structure. One section of the split core opens, allowing the main body to be positioned around the busbar before the removable section is secured. This design supports installation in confined spaces. The transformers use precision-machined, high-permeability silicon-steel cores and high-quality enameled-wire windings for reliable performance.
