Accurate current monitoring with class 0.5 accuracy for reliable metering and protection. Standard secondary output of 5 A corresponding to an 800 A primary (800/5 ratio), suitable for connection to meters, relays, or data acquisition equipment. Robust construction intended for use in industrial environments requiring dependable current sensing. Key attributes Type: splitcore AC current sensor / current transformer Voltage rating: up to 690 V AC Accuracy class: 0.5 Current ratio: 800/5 Primary current capability: 800 A (through conductor) Secondary output: 5 A Installation: split core for clamping around a conductor without disconnecting the circuit Purpose: AC current measurement and transduction for monitoring, metering, and control applications Technical specifications at a glance Rated voltage: 690 V AC Current ratio: 800 A to 5 A Accuracy class: 0.5 Core type: splitcore current sensor Secondary current: 5 A nominal Installation method: clampon around a conductor (split core) Suitable for AC current measurement in systems up to 690 V Applications and use cases Industrial motor and drive monitoring in electrical installations up to 690 V AC, enabling accurate load monitoring and protection coordination. Energy management and submeters in facilities, data centers, or manufacturing sites requiring reliable current data for consumption analysis and efficiency optimization. Retrofit measurement in existing electrical panels or switchgear, allowing realtime monitoring without shutting down power or rewiring, thanks to the splitcore design. Installation and handling notes Ensure the conductor passes through the sensor correctly and only one conductor is enclosed by the core during measurement. Do not leave the secondary circuit open; connect the 5 A secondary to an appropriate burden device (meter, transducer, or data logger) to complete the circuit. Verify that the monitored circuit voltage and current stay within the specified range for accurate results and safe operation. Follow standard electrical safety practices during installation and commissioning. This product aligns with its stated specifications as a 690V rated, 0.5 class AC current transformer with an 800/5 ratio and a splitcore design, intended for easy installation and accurate current sensing in modern electrical systems. It provides a practical solution for voltage, low voltage current measurement needs in industrial and facility environments.
