Split-core design enables installation without disconnecting the circuit, reducing downtime and easing retrofits in crowded panels. The business impact is a faster deployment and lower labor costs, which translates to shorter project timelines and fewer interruptions for critical equipment. In practice, technicians can simply snap the CT-SP-2031-1200-5 around a conductor and proceed with commissioning, making it ideal for panel upgrades and energy-management initiatives. High-current capability with a 1200A primary rating and a 5A secondary output provides accurate measurements in heavy-load environments. The business impact is more reliable metering data for energy accounting, safety, and protection schemes, enabling precise monitoring for feeders, motors, and downstream metering in industrial facilities. This supports better demand management and capacitively aligned protection schemes. Compact window size of 1.97 x 3.15 inches fits standard enclosures and reduces installation footprint, promoting space-efficient retrofits and easier cable management in dense panels. The business impact is improved space utilization and broader compatibility with existing split-core sensors, which translates to faster upgrades and less engineering time. Certifications UL Recognized and CSA Certified support compliance and procurement, accelerating approval cycles and reducing risk in regulated environments. This is particularly valuable in healthcare, data centers, and manufacturing contexts where safety standards are non-negotiable. Rugged yet lightweight at about 1.5 lb with durable construction, it resists vibration and simplifies mounting and routing of conductors, lowering maintenance demands over the sensor’s life. The Eaton ecosystem compatibility further enables scalable deployments from pilot projects to full-scale installations. Accurate performance with .6% accuracy (ACCY) ensures dependable readings across a broad current range, empowering informed energy-management decisions and reliable protection coordination, ultimately driving operational efficiency and cost savings.
