333mV Split-Core
Current Transformer

The AcuCT mV Series is a compact, revenue grade 333mV split-core current transformer engineered for high-precision electrical panel and device monitoring in industrial, commercial, or other demanding environments. The low voltage output is inherently safe, and the split-core design expedites easy installation without disconnecting cables or wires.

  • Revenue grade accuracy: IEC 61869-2 Class 0.5 (from 10%-120% of rated current)
  • Current input range: 20A - 5000A AC (depending on model)
  • Safe, 333mV output
  • Split core design for quick installation
  • UL Recognized

About AcuCT mV Series

Why choose a split-core current transformer with a millivolt output?

Split-core current transformers, which feature a removable "leg" for easy, non-intrusive installation, are specifically engineered for retrofit applications. A common secondary output for split core current transformers is 333mV, which is a low-voltage, millivolt output that is inherently safe. Available in a range of sizes, split core current transformers are ideally suited for general energy measurement, submetering, M&V, or other commercial or industrial applications.
