DX40 Encapsulated Current Transformer — Class 0.5 metering CT (example: 200/5A) A precision metering current transformer engineered to deliver stable, repeatable secondary current for accurate energy measurement and reliable long-term service in commercial and industrial electrical systems. Key benefits Accurate billing and monitoring: Class 0.5 accuracy provides the precision required for revenue metering, submetering and precise energy accounting. Stable, repeatable output: Encapsulated construction reduces environmental effects and drift, ensuring consistent performance for downstream meters and analyzers. Broad primary coverage: Multiple primary options let you match the CT to conductor load without compromising accuracy. Simple integration: Standard CT secondary outputs designed to work directly with energy meters, power analyzers and metering panels. Safety and isolation: Provides galvanic isolation between high-current conductors and low-voltage measurement instruments. Key attributes Model: DX40 Type: Encapsulated metering current transformer Accuracy class: 0.5 (suitable for revenue and precision metering) Primary current options: 150A, 200A, 300A, 400A, 500A, 800A, 1000A Example primary/secondary configuration: 200/5A (200 5A); corresponding secondary ratings available for other primary options as required Function: Produces a scaled secondary current for metering and monitoring devices and isolates primary conductors from low-voltage instruments Compatibility: Intended for use with standard energy meters, power analyzers and metering panels that accept the corresponding CT secondary rating Construction: Encapsulated design for improved environmental protection and long-term stability in panel and switchboard installations Practical use scenarios Utility billing and submetering: Connect to revenue meters in commercial buildings and tenant submetering systems where Class 0.5 accuracy is required. Energy monitoring and management: Feed power analyzers and energy meters in factories, data centers or large facilities for load analysis and efficiency programs. Switchboard and distribution panels: Install on feeder circuits to provide reliable secondary current for panel-mounted meters and monitoring systems. Selection and ordering tips Select the primary rating that matches the maximum expected conductor current (options: 150A, 200A, 300A, 400A, 500A, 800A, 1000A). Confirm the required secondary rating and wiring compatibility with your meter or analyzer; example configuration shown as 200/5A. Use Class 0.5 models where billable-level accuracy is required. Ordering: specify model DX40 and the required primary rating (150A / 200A / 300A / 400A / 500A / 800A / 1000A) and confirm secondary rating (example noted: 200/5A) and any mounting preferences with your supplier. The DX40 delivers metering-grade accuracy and an encapsulated form factor for dependable performance in a variety of electrical measurement applications.
