Product Description
Overview
This UL-certified AC current sensor ensures industrial-grade safety and global compliance, providing reliable and stable performance for power measurement, energy monitoring, and industrial automation applications across factories, smart buildings, and renewable-energy systems.
Featuring high-precision Class 0.2S accuracy and a wide current range from 50 A to 200 A, it delivers precise and consistent current data under fluctuating loads, making it ideal for smart meters, power analyzers, and real-time energy management systems.
The split-core design enables easy, tool-free installation without disconnecting existing wiring, allowing for quick retrofits, system upgrades, and maintenance with minimal downtime, saving labor and installation costs.
Constructed with robust, flame-retardant materials and high dielectric strength, it operates reliably in harsh industrial environments between ‑25 °C and +75 °C, offering long-term durability in control panels, switchgear, and distribution boards.
With OEM/ODM customization options, multiple secondary output types, and recognized certifications including UL, this current transformer is perfectly suited for global B2B buyers seeking precise, safe, and versatile CT solutions for energy monitoring, smart factory integration, and export-ready power systems.

Installation & Best Practices
-
Always de-energize the conductor before installation.
-
Secure primary conductor or busbar through CT window or mount per spec.
-
Connect secondary terminals correctly and maintain burden within specified limits.
-
Avoid leaving secondary open-circuited while primary is energized—risks damage and accuracy error.
-
Use shielded wiring and good earthing practices in high-electromagnetic-noise environments.
-
Verify calibration after installation to ensure accuracy.
