Amperage rating of 150A primary with a 5A secondary output provides accurate, standard current data for metering and protection. This directly improves energy accounting accuracy and compatibility with standard meters, enabling engineers to rely on a consistent signal for protection relays and energy dashboards. Application-ready for panel metering and distribution monitoring, it reduces measurement uncertainty and supports reliable fault detection. Split-core construction allows technicians to install or upgrade without opening live circuits, shortening project timelines and reducing labor costs. The 2"x2" window accommodates common busbar configurations, enabling quick retrofits in crowded panels with minimal wiring changes. Certifications of UL Recognized and CSA Certified provide compliance confidence for industrial installations and OEM assemblies. With a compact 4.4 in by 4.4 in footprint and a light 1.5 lb weight, mounting is straightforward in tight panel spaces. The 150A primary / 5A secondary spec is widely compatible with Eaton meters and protective relays, ensuring seamless integration into existing energy-management ecosystems.

FAQs
The CT-SP-200R-150-5 uses a split-core design that permits opening the CT around an existing busbar without de-energizing the circuit. Ensure the panel is de-energized per site safety procedures, then place the CT around the conductor, close the core, and route the 5A secondary wiring to your metering or control device. Verify polarity and alignment with the meter's input range for accurate readings.
Yes. The CT-SP-200R-150-5 provides a standard 5A secondary output compatible with Eaton metering modules and most protection relays designed for 5A CT inputs. Its 150A primary rating matches common distribution loads, enabling direct integration into energy management dashboards, SCADA, and relay configurations without custom signal conditioning.
The CT-SP-200R-150-5 is UL Recognized and CSA Certified, signaling adherence to core safety and performance standards for electrical energy measurement devices. These certifications reduce compliance risk in industrial environments, facilitate procurement in regulated projects, and support validation during audits and quality assurance processes.
The transformer has a footprint of 4.4 in length, 4.4 in width, and 1.25 in height, with a weight of 1.5 lb. The 2"x2" window accommodates common busbar configurations, making it suitable for crowded panels. When mounting, ensure clearance for the secondary leads and room for routing to meters or relays, while avoiding close proximity to heat-generating components.
Benefits include faster retrofit times due to the split-core design, reducing labor costs and downtime. The standard 150A/5A specification provides consistent metering signals that improve energy accounting accuracy, lowering misreadings and enabling tighter energy-management controls. Certifications and robust construction also minimize compliance risk and maintenance rework over the device’s lifecycle.
