Description:
The Accuenergy AcuCT mV Series is a compact, revenue-grade 333mV split-core current transformer engineered for high-precision electrical panel and device monitoring. Its low-voltage millivolt output is inherently safe and connects directly to any meter with 333mV CT inputs. Four window sizes cover 50A to 5000A AC: AcuCT-075 (19 x 19mm, 50-200A), AcuCT-125 (31.8 x 31.8mm, 100-600A), AcuCT-200 (50.1 x 50.1mm, 200-1500A) and AcuCT-3050 (76.2 x 127mm, 400-5000A). All models are 1% accuracy, epoxy encapsulated, supplied with 2.5m (8ft) leads and are UL Recognised, CE and RoHS.
