- Model and design: AKH0.66 Dia.16 mm current meter transformer with a split-core design for easy clamp-on installation around a conductor without disconnecting power. - Ratings and adjustability: Primary rating 120 A with a secondary rating of 40 mA, and it can be configured to 40 A / 20 mA. - Size and compatibility: Compact 16 mm diameter form factor suitable for tight spaces and retrofits. Secondary current is compatible with meters and measurement devices that accept 40 mA, with an option to set to 20 mA. - Installation and performance: Split design enables quick installation on existing circuits, enabling non-invasive current measurement in AC systems. The configuration capability allows adaptation to different metering inputs without replacing equipment. - Use scenarios: - Retrofit energy monitoring in existing electrical panels without circuit shutdown, enabling ongoing load tracking. - Sub-metering in commercial buildings to monitor individual loads such as lighting, HVAC, and office equipment for energy management. - Motor and equipment load monitoring in manufacturing or processing facilities to detect abnormal current, improve efficiency, and support maintenance planning.
