Split-core design allows tool-free installation around existing conductors, eliminating the need to unwind cables and shut down feeders. This reduces commissioning time and on-site labor costs during retrofit or expansion projects. It is particularly valuable in control panels and meter enclosures where uptime matters. The 800A primary and the 5A secondary output provide compatibility with standard metering electronics while minimizing secondary wiring complexity. This pairing delivers direct signal compatibility with most energy meters and protection relays, enabling rapid integration into new or existing electrical systems. With .6% accuracy, the CT-SP-3147-800-5 delivers reliable measurement data even under transient loads. This improves energy accounting, power quality analysis, and billing accuracy for industrial facilities. The generous 3.15 x 4.72 inch window accommodates standard bus bars and conductor configurations, simplifying retrofits in tight spaces. UL Recognized and CSA Certified ratings streamline compliance for panel builders and integrators. These certifications support qualified procurement and reduce risk during audits. With a compact footprint—7.28 inches long, 5.67 inches wide, 1.97 inches tall—and a light 1.5 lb weight, the sensor fits into crowded enclosures without thermal concerns. The robust construction supports reliable operation in harsh industrial environments.
