Splitcore current transformer AKH0.66K is a class 0.5 device with a 16 mm diameter opening and rated currents of 40 A / 20 mA. It is designed for easy installation around an existing conductor without disconnecting wiring, making it suitable for retrofits and new installations alike. Key benefits - Non intrusive installation: split-core design allows opening around a live conductor for quick mounting without wires disconnection. - Accurate measurement: class 0.5 performance provides reliable current sensing for energy monitoring and load analysis. - Clear current transformation: primary rated current 40 A to secondary 20 mA offers a defined, proportional output for monitoring and instrumentation. - Compact and versatile: 16 mm diameter opening supports compact installations in panels, switchgear, and control cabinets. - Low maintenance and robust: designed for dependable operation in typical electrical environments. Important attributes - Function: splitcore current transformer for measuring AC current - Compatibility: secondary current up to 20 mA, suitable for interface with meters, data loggers, and instrumentation when paired with an appropriate burden resistor - Size: 16 mm diameter opening for conductor insertion - Material and construction: specified as a split-core assembly with class 0.5 accuracy (no additional material details provided) - Performance: rated primary current 40 A, secondary current 20 mA; class 0.5 accuracy Use scenarios - Retrofit energy monitoring in an electrical panel: slip the conductor through the opening, snap the core shut, and connect the secondary output to a measurement device to track real-time current and energy usage. - Motor or HVAC load monitoring: install around a single conductor feeding a motor or air handling unit to observe current draw, detect overloads, and improve maintenance scheduling. - Data logging and sustainable building management: use with appropriate burden and instrumentation to log current trends for demand forecasting, efficiency analysis, and fault detection. Notes - The transfer ratio is 40 A primary to 20 mA secondary, suitable for integration with compatible sensing equipment and burden conditions. - The description preserves the model AKH0.66K, class 0.5, 16 mm opening, and the rated currents, ensuring consistency with the original product specifications and intended use.
