Schneider Electric EMCT083 Split Core Current Transformer

Schneider Electric's EMCT083 Split Core Current Transformer is a clamp-on sensor used to measure high currents for PowerLogic energy meters and Schneider Electric monitoring systems. It supports up to 800 A on the primary side and provides a 5 A secondary output, delivering a 160:1 turns ratio that feeds standard 5 A inputs in meters and controllers. The device features a 3-inch (size 3) split-core window, enabling installation around an existing conductor without powering down equipment, which is ideal for retrofit projects in commercial and light-industrial panels. A burden rating of 12.5 VA at rated current defines the maximum impedance the CT can drive while maintaining accuracy, helping installers select compatible wiring and burden loads. The EMCT083 is part of Schneider Electric's PowerLogic family of current transformers and is designed to work with their energy meters and monitoring modules to capture precise current measurements for demand calculations, power quality analysis, and overall energy management. Typical applications include monitoring feeders and individual motors in distribution boards, service-entrance measurement in retrofit projects, and expansion of existing metering capabilities without replacing entire meters. Installation emphasizes proper orientation of the primary conductor through the window and correct secondary wiring per the device wiring diagram to ensure accurate, reliable readings in 50/60 Hz networks.
