The AcuCT mV Series represents a compact, high-precision split-core current transformer engineered for revenue-grade performance in electrical panel and device monitoring within demanding environments like industrial and commercial settings. Its inherently safe low-voltage output ensures user safety, and the split-core design streamlines installation, eliminating the need for cable or wire disconnection.
Key Features:
-
Revenue Grade Accuracy: Adheres to IEC 60044-1 class 0.5s standards within the 10%-120% range of the rated current.
-
Current Input Range: Covers a broad range from 20A to 5000A AC, varying by model.
-
Safe 333mV Output: The low-voltage output prioritizes safety during operation.
-
Split-Core Design: Facilitates quick and hassle-free installation, saving time and effort.
-
UL Recognized: Meets the safety and performance standards recognized by Underwriters Laboratories (UL).
