OPCT Split-Core Current Transformer, 0.5 Class Precision, 1000/1~5000/1 Transformation Ratio, 10/16/24/35mm Hole, Clamp-On AC Current Sensor with Optional RJ12 Output

The OPCT series split-core (open/closed) current transformers are high-precision clamp-on sensors designed for AC current metering and monitoring, ideal for applications where cables cannot be disconnected. With 0.5 class accuracy and ratios from 1000:1 to 5000:1, they deliver reliable performance for power grids, EV chargers, and 5G base stations.

✨ Key Features


✅ Split-Core Design: No need to cut cables, easy installation with clamp-on mechanism.

✅ Multiple Ratios & Apertures: Ratios: 1000:1/2000:1/3000:1/4000:1/5000:1; Apertures: 10mm/16mm/24mm/35mm.

✅ High Precision: 0.5% accuracy, 0.3~0.5% linearity error, suitable for high-frequency (up to 200kHz) metering.

✅ Premium Materials: Ferrite core with mirror-polished contact surfaces for low loss; high-quality enameled copper winding for durability.

✅ Safety & Reliability: Built-in transient suppression diodes (anti-open circuit design), UL94-V0 flame-retardant housing, 2kV/1min withstand voltage.

✅ Flexible Output: Standard red/black leads or RJ12 network port (3-in-1) output options.

✅ Wide Operating Range: 50Hz~200kHz frequency, -30℃~+70℃ operating temperature, suitable for harsh environments.
