Split-Core Current Transformers

Split-core current transformers provide accurate measurements of AC electrical systems and feature a removeable or hinged leg for easy installation without disconnecting wires or interrupting power. Both retrofit and semi-permanent metering applications can benefit from the split-core’s non-invasive design.

SPLIT-CORE CURRENT TRANSFORMERS

AcuCT R Series

Revenue grade, IEC 61869-2 Class 0.5 split-core AC current transformer with multiple window sizes & many output rating choices including 80mA, 333mV, & 5A. Use on services from 5A-5000A (depending on model). Split-core form factor simplifies installation. UL Listed for XOBA UL2808 Standard.
