Feature → Business Impact → Application: The split-core current transformer design supports non-invasive installation around existing conductors, reducing panel downtime and accelerating retrofits, which translates to faster project timelines in industrial facilities and improved time-to-value for energy monitoring. This enables precise current measurement with a 300 A primary rating and a 5 A secondary output, delivering reliable data for energy management and protection schemes in manufacturing lines and distribution panels. The 1.2% accuracy (ACCY) improves metering fidelity, supporting compliance reporting and more accurate demand calculations. A compact 4.4 in by 4.4 in footprint and 1.25 in height saves panel space in crowded switchgear, enabling scalable installations across multi-panel ROIs and reducing spare parts inventory. Certifications UL Recognized and CSA Certified provide procurement confidence and regulatory alignment, easing supplier qualification and audit readiness. The 2" x 2" window accommodates common feeder geometries and bus bars, facilitating quick and repeatable installations in retrofit projects, new builds, and upgrade programs. Weight at 1.5 lb offers a rugged yet manageable option for field mounting in harsh industrial environments while maintaining ease of handling during installation and testing.

FAQs
The CT-SP-200R-300-5 is a split-core current sensor that snaps around a bus bar or conductor without disconnecting power. Its 2 x 2 in window accommodates typical feeders, and the compact 4.4 x 4.4 in profile fits crowded panels. Simply align, close the core, and connect the 5 A secondary output to your metering input.
Key specs include a 300 A primary rating with a 5 A secondary output, and 1.2% accuracy (ACCY) for reliable metering. The device features a split-core design with a 2 in by 2 in window, and a compact footprint of 4.4 in length and width and 1.25 in height. It weighs about 1.5 lb and carries UL Recognized and CSA Certified safety markings.
Yes, it is well-suited for panel metering and energy management across industrial facilities. The 5 A secondary output is designed for direct connection to metering instrumentation while the 300 A primary handles typical mains and feeders. Its accuracy and small footprint support continuous monitoring, demand calculation, and energy analytics without intrusive installation, enabling scalable metering programs.
CT-SP-200R-300-5 carries UL Recognized and CSA Certified marks, providing essential safety and compliance for electrical assemblies in North American facilities. These certifications help with procurement by reducing supplier risk and streamlining approval processes for panel builders and integrators. Always verify current certificates on Eaton's datasheets and ensure your metering equipment is compatible with 5 A secondary current sensors.
Using CT-SP-200R-300-5 can reduce commissioning time and wiring complexity, lowering labor costs during installation and upgrades. Its solid-state performance and compatibility with standard energy meters support accurate data capture for ongoing energy optimization and demand reduction. Routine checks focus on connector integrity and calibration intervals, with minimal contact maintenance due to a passive, non-dissipative design.
