FAQs
To install, first power down the panel and open the split-core window. Position the CT around the target conductor with the correct polarity as indicated by your metering/monitoring device. Close and secure the core, then connect the 5A secondary leads to the measuring device. Verify alignment and perform a basic functional check to confirm accurate readings.
The sensor provides a 2000A primary rating with a 5A secondary output, delivering measurements with approximately 0.6% accuracy. It features a 7.28 in length, 5.67 in width, 1.97 in height, a 3.15 x 4.72 in window, and a weight of about 1.5 lb, suitable for large-load monitoring.
Yes. The CT-SP-3147-2000-5 carries CSA Certified and UL Recognized safety certifications, providing confidence for electrical installations in regulated environments and aiding in compliance and audits.
This sensor is ideal for energy metering, submetering, load monitoring, and power management in electrical panels, switchgear, and retrofit projects where large current monitoring is required without extensive rewiring or disassembly of equipment.
Ensure the conductor fits within the 3.15 x 4.72 in window, maintain proper orientation, and keep the mounting clear of moisture and dust. Use the 5A secondary outputs to feed a compliant meter or controller. Adhere to CSA UL guidelines and manufacturer torque specs to ensure reliability and regulatory compliance.
