What it is - The 5A Clamp Current Transformer is a clamp-on current sensor that measures current in electrical conductors without disconnecting or modifying the circuit. Key specs and performance - Current ratio: 300/5 A (60:1 turn ratio). This converts a high primary current up to 300 A into a 5 A secondary signal for measurement. - Function: current sensing with an accurate, defined ratio to support reliable monitoring and measurement. - Design: compact clamp that can be easily installed around a single conductor in typical electrical environments. - Compatibility: intended for use with instruments and systems that accept a 5 A CT input, such as meters, data loggers, and control equipment. - Isolation and safety: provides non-contact current measurement while maintaining electrical isolation between the primary circuit and measurement equipment. Why you need it - Safe, non invasive current measurement: measure current without breaking the circuit or exposing personnel to live conductors. - Accurate monitoring: defined 300/5 A ratio enables precise readings when paired with compatible measurement devices. - Space efficient and easy to install: clamp design simplifies installation in cramped or crowded electrical panels. - Flexible integration: works with standard 5 A CT inputs across a range of measurement and control devices. How it helps in practice - Use scenario 1: Motor and drive monitoring in manufacturing. Clamp around the motor feed conductor to continuously track current draw for efficiency, overload prevention, and maintenance planning. - Use scenario 2: Energy management in facilities and data centers. Place CTs on individual feeders or critical loads to collect current data for energy usage analysis and demand management. - Use scenario 3: Commissioning and testing of electrical systems. During setup or service, rapidly verify current levels and validate system performance without altering connections. Installation guidance - Clamp around a single conductor only for each measurement point. - Connect the CT secondary to the measurement instrument designed for a 5 A input. - Ensure proper polarity as required by the monitoring system and avoid routing multiple conductors through a single clamp. Notes - The 300/5 A current ratio indicates its conversion capability from high primary currents to a 5 A secondary signal, enabling compatible, accurate current sensing with standard measurement equipment.
