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 60044-1 0.5s class 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.
SPLIT-CORE CURRENT TRANSFORMERS
AcuCT 5A Series
Revenue grade, IEC 60044-1 0.5s class split-core AC current transformer. Four sizes available with choice of 1A or 5A output for industrial applications. Use on services from 5A-5000A (depending on model). Split-core design simplifies installation without conductor disconnection.
SPLIT-CORE CURRENT TRANSFORMERS
AcuCT mV Series
Revenue grade, IEC 60044-1 0.5s class split-core AC current transformer. Four sizes available, each with a safe 333mV output. For use on services from 20A-5000A (depending on model). Split-core design accelerates installation without conductor disconnection.
SPLIT-CORE CURRENT TRANSFORMERS
AcuCT Hinged Series
Hinged split-core AC current transformer with 0.5% high accuracy measurements. Four sizes available, each with a safe 333mV output. Use on services from 5A-630A (depending on model). Compact form factor is superior in crowded panels & hinged split-core design promotes fast installation.
