AKH0.66/K16(40100) A/10mA Split Core Current Transformer — 660V AC Rated Voltage Key benefits Simple, nonintrusive installation: splitcore design allows clamping around conductors without disconnecting wiring or interrupting service. Accurate, safe secondary signal: converts primary AC current (40–100 A) to a standardized 10 mA secondary output for monitoring and protection equipment. Suitable for live systems up to 660V AC: rated for use in mediumvoltage distribution and control panels where 660V insulation and isolation are required. Versatile compatibility: designed to interface with meters, control systems, data loggers, and protective relays that accept a 10 mA CT secondary. Main attributes Model: AKH0.66/K16 Type: Split core current transformer (clampon) Primary current range: 40–100 A Secondary output: 10 mA Rated voltage: 660V AC Form factor: K16 splitcore housing for easy mounting in confined spaces Function: Provides isolated, proportional current signal for measurement, metering, and protection Why customers need it Eliminates downtime: install or retrofit current sensing without shutting down circuits. Enables safe measurement: secondary output provides a lowenergy signal isolated from the voltage primary for safe connection to instrumentation. Simplifies upgrades: ideal when replacing or adding monitoring equipment in existing switchboards, control panels, or machinery without rewiring. Compatibility and performance notes Use with devices that accept a 10 mA CT secondary input. Rated for systems with linetoline or linetoneutral voltages up to 660V AC. Splitcore design minimizes installation labor and reduces risk during retrofits or maintenance. Typical applications Industrial energy monitoring: clamp around feeders to provide a continuous current input to energy meters or data loggers for load profiling and cost allocation. Motor and equipment load monitoring: track motor currents on existing cabling to detect overloads, imbalance, or efficiency losses without interrupting service. Retrofit metering in commercial and utility panels: add current sensing to existing distribution boards for submetering, power quality studies, or protective relay inputs. Installation tips Ensure the conductor passes through the CT window fully and is centered for measurement stability. Verify that the connected instrumentation is configured for a 10 mA CT secondary and the CT primary current range (40–100 A) matches expected load. Follow standard safety practices when working in live cabinets, and secure the CT housing and secondary wiring to prevent movement or accidental shorting. The AKH0.66/K16(40100) A/10mA Split Core Current Transformer delivers a practical, safe, and easytoinstall solution for current measurement and monitoring in systems rated up to 660V AC.
