AC Current Sensor Transformer, Core Current Transformer Coil Sensor for 200A Amp Energy Meter

Key features

• All-Scenario No-Power-Cut Current Monitoring：scenarios like live retrofits in substations/workshops, online monitoring for motors/frequency converters, post-construction current metering in buildings, and temporary testing during power maintenance—avoiding downtime losses while realizing flexible current measurement and signal transmission (compatible with ammeters, PLCs).
• Split Core Structural Advantage - Detachable core design eliminates the need for cable threading or power-off during installation, solving the pain point of difficult disassembly and assembly of traditional closed transformers, especially suitable for fixed cables in cable trays or existing circuits.​
• Stable Accuracy and Broad Compatibility—Featuring accuracy classes ranging from 0.5 to 1, with a 24mm inner diameter, it meets daily current measurement needs. Supporting a rated current range of 50A to 1000A, it is compatible with low-voltage circuits (AC 0.4kV and below) and can be paired with common monitoring devices such as ammeters, energy meters, and PLCs.
• Effortless Installation & Disassembly - No complex tools required, the core can be closed and fixed quickly by hand or with simple tools, reducing installation time to within 5 minutes; it is also easy to disassemble, making it convenient for temporary use or later maintenance.​
• Stable operation—achieves electrical isolation between high-current main circuits and low-current auxiliary circuits, effectively preventing high-voltage hazards from affecting monitoring equipment and personnel, and proving highly effective in industrial and building electrical applications.
