690V 2000A Low Voltage Current Transformer

AKH-0.66/100 × 80II low voltage current transformer rated for 690V primary insulation voltage and 2000A nominal primary current, delivering 5A secondary output. Dimensions: 100mm × 80mm core aperture (standard AKH-0.66 series footprint), lightweight and compact design suited for panel mounting in confined electrical enclosures. Constructed with flame-retardant, thermally stable insulating materials for long-term reliability under continuous load. Provides accurate AC current measurement and monitoring for energy management systems, submetering, and protection relays. Optimised for stable performance across industrial, commercial and residential low-voltage distribution networks (up to 690V AC). Features high short-time thermal withstand capability and consistent ratio accuracy per IEC 61869-2. Designed for fixed installation in switchgear, metering cabinets and automation panels — ideal for real-time load monitoring, demand-side management and integration with building energy management systems (BEMS) or SCADA platforms.
