QACT series: Split-Core Current Transformers

The QACT split-core current transformer series from HQsensing brings revenue-grade accuracy, field safety and lightning-fast installation to any project that needs dependable current feedback from rooftop solar inverters and EV fast-chargers to data-centre branch circuits and smart-building energy dashboards. Rated from 5 A to 600 A, each model opens on durable, spring-loaded hinges so you can snap the CT around a live conductor in seconds no lugs to loosen, no downtime, no arc-flash PPE beyond your facility’s baseline.

An internal magnetic alignment plate guarantees full core contact after closing, delivering ±1 % linearity across 1 %-120 % of primary rated current, even under the aggressive harmonics and load swings common in motor drives and photovoltaic inverters.
