Supported Applications
The ACI AcuCT Split Core Current Transformers are designed to convert an AC operating current into a low voltage AC millivolt signal for use with microprocessor-based circuits requiring maximum accuracy and precision. These compact, lightweight split-core transformers facilitate installation on branch circuits within electrical panels without disconnecting cables.
Models in this series are compatible with specific Single or 3 Phase ACI power meters where typical power measurements are required, including the KW350-P1-D-S-SC, KW320-P1-D-W-SC-XX, KW320-P1-D-W-SC-PC, KW1850-P1-D-W, and KW1850-P1-D-S Power Meters.
Operating Conditions & Performance
The series monitors AC Current with a rated output of 333mV at specified amperages ranging from 50 to 1000 Amps. Accuracy is defined as 0.5% from 10-120% of Rated Current per IEC 60044-1 standards.
Key operating parameters include:
- Maximum Working Voltage: 600 VAC, Category III
- Withstand Voltage: 3,000VAC
- Operating Frequency Range: 50/60Hz
- Operating Temperature Range: 5 to 140°F (-15 to 60°C)
- Storage Temperature Range: -40 to 185°F (-40 to 85°C)
- Humidity Rating: 5 to 95%, non-condensing
- Maximum Elevation: 9,842 ft (3 Kilometers)
The core style is Split-Core (non-hinged). For maximum performance, the source notes that core contacts should be wiped clean and free of debris.
Configuration Options
The series offers configurable window sizes to accommodate different conductor dimensions across three primary form factors: AcuCT-075 Series, AcuCT-125 Series, and AcuCT-200 Series. Additional larger variants are available in the product line.
Window Sizes & Dimensions
- AcuCT-075 Series: Window 0.748" (19 mm) x 2.008" (51 mm); Overall dimensions 2.00" (50.80 mm) x 2.09" (53.30 mm) x 0.669" (17.00 mm)
- AcuCT-125 Series: Window 1.26" (32 mm) x 3.366" (85.5 mm); Overall dimensions 3.25" (82.50 mm) x 3.35" (85.10 mm) x 1.02" (26.00 mm)
- AcuCT-200 Series: Window 2.008" (51 mm) x 5.02" (127.5 mm); Overall dimensions 4.76" (121.00 mm) x 5.00" (127.00 mm) x 1.18" (30.00 mm)

Key Product Differences
Variants are distinguished by rated current capacity and window size to match specific conductor requirements. The ordering grid lists models with ratings of 50A, 100A, 200A, 300A, 400A, 600A, 800A, and 1000A.
Model numbering follows the pattern AcuCT--:333. For example, AcuCT-075-50:333 denotes a 0.75" window size rated for 50 Amps with a 333mV output.
Lead length variations are indicated in the model or ordering grid; standard lead lengths are typically 8 ft (2.5m), while specific models such as AcuCT-125-400:333-10M offer extended leads of 32 ft (10m).
