Description:
The Accuenergy AcuCT Hinged Series is a family of high-accuracy, ultra-compact hinged split-core current transformers with a safe 333mV output, designed for monitoring branch circuits in crowded electrical panels. The installer-friendly hinged design snaps around the conductor for rapid installation. Four round window sizes cover 1A to 600A: AcuCT-H040 (10.2mm), AcuCT-H063 (16mm), AcuCT-H100 (25.4mm) and AcuCT-H138 (35mm). Accuracy is 0.5% class, with the H100 and H138 compliant with IEC 61869-2 Class 0.5. All models ship with 2.5m (8ft) leads, operate from -25°C to 70°C and are UL Recognised, CE and RoHS.
