AKH0.66K split-core current transformer - Accuracy class 0.5, split-core design for noninvasive current measurement - Conductor window diameter: 16 mm - Primary current rating: up to 100 A - Rated burden: 40 mA - Split-core construction enables easy installation without disconnecting the circuit - Ideal for measurements where circuit downtime must be avoided Key benefits and why you need it - Noninvasive monitoring: clamp around an existing conductor without power interruption, preserving safety and continuity. - Quick installation: the split-core design allows tool-free clamping and removes the need to open the circuit or rewire. - Reliable readings: class 0.5 accuracy provides dependable data for monitoring, energy management, and fault detection. - Compact and compatible: 16 mm conductor window fits common cables; suitable for integration with standard metering and monitoring equipment that expects a CT input. - High current capability with low burden: supports up to 100 A while keeping the burden at 40 mA for accurate measurement with minimal loading on the measurement system. Applications and use scenarios - Retrofit energy monitoring in existing electrical panels: clamp around a live conductor to measure load and feed data to a power meter, data logger, or energy management system without turning off equipment. - Motor and HVAC equipment monitoring: clamp around motor feeders or service lines to track current draw, detect overloads, and support condition monitoring or efficiency audits. - Renewable and EV charging installations: use on AC circuits from solar inverters, batteries, or charging stations to monitor current flow for performance, safety, and usage analytics. Installation notes - Open the split core, place around the target conductor, and close the core to complete the measurement. No circuit disconnection required, enabling fast and low-risk installation.
