Industrial SCT-019 Split Core Current Transformer

The SCT-019 Split Core Current Transformer from YHDC is a non-invasive, clamp-on sensor that measures AC current up to 200 A with a 0.333 VAC output at rated current. Its split-core design lets you install it without disconnecting conductors, making it ideal for electrical distribution panels, energy management systems, building automation, solar installations, and industrial automation needing non-contact current sensing. Key specs include a 200 A rated primary, 300 A maximum detection current, 0.5%–1% accuracy depending on configuration, Permalloy core, 19 mm × 19 mm window, 20 Hz to 1 kHz frequency range, insulation rating up to 660–720 VAC, dielectric strength of 2.5 kV AC for 1 minute, and a voltage output with an integrated burden resistor. It supports suspended or clamp-on mounting, operates from -25°C to +70°C, and uses UL94-V0 flame-retardant materials, aligning with energy monitoring and industrial power measurement applications such as power meters, energy analyzers, BMS, and monitoring relays.
