The ESCT-B812 Series Split Core Current Transformer is a reliable and precise instrument designed for measuring high primary currents ranging from 600A to 1500A, with a standard 5A secondary output. Its split core design is one of its standout features, allowing for straightforward installation around existing cables and conductors without the need to disconnect or interrupt live circuits — saving time and reducing downtime in industrial and commercial electrical systems. Operating across a frequency range of 50-60Hz and rated for continuous use at 600Vac insulation voltage, this transformer is built for demanding environments. The phase angle error stays under 2 degrees at 50% of rated current, ensuring accurate and dependable metering performance. Available in multiple sizes to suit various busbar and cable configurations, the ESCT-B812 Series is a practical solution for energy monitoring, power metering, and protection applications.
