The SCT-019 split core current transformer delivers non-invasive AC current measurement at a rated 50 A primary with a 0.333 VAC output. Its 19 mm × 19 mm window and clamp-on construction permit installation around live conductors without disconnecting circuits, suiting retrofit work in electrical distribution panels, building management systems, photovoltaic arrays, generator monitors, and branch-circuit metering. The permalloy core supports 20 Hz–1 kHz frequency response, ±0.5 % to ±1.0 % accuracy, 2.5 kV dielectric strength, and operation from −25 °C to +70 °C while maintaining UL94-V0 flame rating.
