Eaton 30502SH Solid Core Instrument Transformer

The Eaton 30502SH functions as a solid core instrument transformer engineered to provide accurate current reduction for electrical monitoring within power distribution networks operating up to 600 Volts. Featuring a primary winding rating of 500 Amperes stepped down to a secondary output of 5 Amperes, the unit utilizes a 3-inch circular window designed to accommodate thick conductors that must be passed directly through the magnetic core assembly during installation procedures. Because the single-piece construction does not feature a hinged or split opening, this component serves as a permanent fixture typically employed in new construction or complete rewiring projects where precise measurement of continuous load current is necessary for connected instrumentation. This functional isolation protects sensitive downstream electronic controls from high-voltage exposure while delivering a normalized 5-ampere signal ideal for integration with protective relays or management systems utilized for utility monitoring and facility energy audits.
