AKH0.66K10 40A/20mA CT Current Transformer Coil - Function and purpose The AKH0.66K10 CT Current Transformer Coil is a current transformer designed to transform current in an electrical circuit. It enables accurate measurement by converting a high primary current to a low-level secondary signal for monitoring and control. - Current ratio and performance Primary current: up to 40 A. Secondary current: 20 mA. This 40 A to 20 mA ratio provides a safe, low-level signal for instrumentation while preserving measurement accuracy for monitoring and control tasks. - Model and specifications Model: AKH0.66K10. The current transformer coil uses a defined 40A/20mA ratio to indicate its specifications and intended operating range. - Why you need it - Enables accurate current measurement without exposing meters or controllers to high currents. - Provides a low-level signal suitable for data acquisition, relays, and control systems. - Supports reliable current sensing for monitoring, protection, and load management. - Compatibility and integration Suitable for electrical systems and equipment that require CT input for monitoring and control. Works with instrumentation, meters, protection relays, and PLCs that accept CT-derived signals. - Use scenarios 1) In an electrical panel to monitor feeder currents and feed data to a metering or monitoring system. 2) In energy metering installations to convert high currents to a 20 mA secondary signal for data logging. 3) In protection or control circuits to provide a safe, low-current input for relays or controllers that detect overcurrent conditions. - Quick reference Model AKH0.66K10, current ratio 40A/20mA, CT Current Transformer Coil, designed for current monitoring and control in electrical systems.
