S77-Solid-Core

Current Transformers

Easy split-core installation: ACUCT Split Core Current Transformers install around existing branch circuit conductors without disconnecting cables, reducing panel downtime.
Designed for power metering: Converts AC operating current into a 333 mV signal for use with ACI single-phase and three-phase power meters.
Multiple current ranges: Available in 50A, 100A, 200A, 300A, 400A, 600A, 800A, and 1000A models to match a wide variety of electrical monitoring applications.
High measurement accuracy: Provides 0.5% accuracy from 10% to 120% of rated current, supporting dependable energy and demand metering.
Built for branch circuit monitoring: Compact, lightweight designs with 0.75", 1.25", and 2.00" window sizes make it easier to fit conductors inside electrical panels.
Ideal for efficiency projects: Well suited for energy metering, demand metering, load surveys, LEED/green projects, and ROI or project-justification studies.
Durable electrical construction: Epoxy-encapsulated UL94V-0 case, 600 VAC Category III rating, and 3,000 VAC withstand voltage support demanding panel environments.
Installer-friendly wiring: Stripped and tinned 22 AWG lead wires with polarity identification simplify connection to compatible ACI power meters.
Certified and supported: UL Recognized, CE, and RoHS2 compliant, with ACI’s five-year limited warranty for long-term confidence.
