Split Core Current Transformer 4000A 5A Clamp On CT AKH0.66/K Accurate Current Conversion Easy Installation

Splitcore clampon current transformers for converting primary currents to a standard 5A secondary output. Two models available with large rectangular windows for easy installation and reliable measurement. Key benefits Simple installation: splitcore clampon design lets you fit the transformer around live conductors without interrupting service. Standardized output: converts primary currents to a 5A secondary suitable for energy meters, instruments, and protection relays. Fits large conductors: generous window sizes accommodate wide busbars and multicore cable bundles. Clear model options: available in CT160x80 with a 3000A to 5A ratio, and AKH0.66/K CT168x80 with a 4000A to 5A ratio for highercurrent applications. Stable performance: designed to provide consistent secondary current proportional to primary current for accurate system monitoring and protection. Key specifications Model CT160x80 3000A 5A: splitcore clampon current transformer, window size 160x80 mm, primary rating 3000 A, secondary output 5 A. Model AKH0.66/K CT168x80 4000/5: splitcore clampon current transformer, window size 168x80 mm, primary rating 4000 A, secondary output 5 A. Attributes customers need to know Function: steps down large AC currents to a measurable 5A secondary for meters and protective devices. Compatibility: designed for use with standard 5A metering equipment, protection relays, power monitoring systems, and switchgear that accept a 5A secondary input. Size: rectangular splitcore windows of 160x80 mm and 168x80 mm to fit larger conductors and bus structures. Construction: splitcore housing for quick clampon mounting and secure closure to maintain electrical continuity and measurement accuracy. Performance: available primary ratios 3000/5 and 4000/5 to suit different current ranges while preserving proportional secondary output. Typical applications Retrofit energy monitoring: install around main feeders or branch circuits to feed existing 5A meters without disconnecting conductors. Substation or panel measurement: monitor current busbars or large cable runs where conventional solidcore transformers are impractical. Temporary testing and diagnostics: clamp on for shortterm load measurements, commissioning, or troubleshooting in industrial and commercial electrical systems. Installation and use notes Mount by opening the split core, placing around the conductor, and securing the core until closed. Connect the secondary terminals to your 5A input device following standard wiring practices. Select the CT model with the appropriate primary rating and window size to ensure conductor clearance and correct scaling to the 5A secondary. These units are intended to transfer proportional current to a 5A measuring device; do not leave the secondary opencircuited under load. Choose the CT160x80 3000A 5A or AKH0.66/K CT168x80 4000/5 to add accurate, nonintrusive current measurement to your electrical monitoring and protection systems.
