Encapsulated Current Transformer DX40 — Class 0.5 metering CT (200 5A) A precision metering current transformer designed for accurate energy measurement and reliable service in commercial and industrial electrical systems. The DX40 offers Class 0.5 accuracy and an encapsulated build to provide stable, repeatable output for downstream meters and monitoring equipment. Key benefits Accurate billing and monitoring: Class 0.5 accuracy ensures measurements suitable for revenue metering and precise energy accounting. Versatile primary ratings: Available in multiple primary currents (150A, 200A, 300A, 400A, 500A, 800A, 1000A) to match a wide range of distribution and equipment loads. Metering output: Models are configured for metering use; example configuration indicated as 200 5A (200/5A secondary), with corresponding secondary ratings for other primary options as required. Robust, encapsulated construction: Encapsulation improves environmental protection and longterm stability in panel and switchboard installations. Easy integration: Designed for use with standard metering devices and energy management systems to deliver a consistent secondary current for measurement. Key attributes Model: DX40 Type: Encapsulated metering current transformer Accuracy class: 0.5 Primary current options: 150A, 200A, 300A, 400A, 500A, 800A, 1000A Example primary/secondary configuration shown: 200 5A (200/5A) Functionality: Provides a scaled secondary current for metering and monitoring devices; isolates primary currents from lowvoltage measurement 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 enhanced protection and stability in electrical enclosures Applications / use cases Utility billing and submetering: Integration with revenue meters in commercial buildings and tenant submetering systems where Class 0.5 accuracy is required. Energy monitoring and management: Feeding metering devices and power analyzers in factories, data centers, and large facilities to support energy efficiency programs and load analysis. Switchboard and distribution panels: Installation on feeders and distribution circuits to provide reliable secondary currents for panelmounted meters and monitoring systems. Selection tips Choose the primary rating that matches the maximum expected conductor current (options: 150A, 200A, 300A, 400A, 500A, 800A, 1000A). Confirm the secondary rating and wiring compatibility with your meter or analyzer; example configuration is shown as 200 5A (200/5A). Use Class 0.5 models where accurate metering and billinglevel precision are required. Ordering information Model: DX40 Specify required primary rating when ordering (150A / 200A / 300A / 400A / 500A / 800A / 1000A) Confirm secondary rating (example noted: 200 5A) and any additional installation or mounting options with the supplier The DX40 encapsulated current transformer delivers meteringgrade accuracy and a robust form factor for reliable performance in a variety of electrical measurement applications.
