Overview
The Carlo Gavazzi CTA6X300A5A is a split-core industrial current transformer designed for electrical monitoring applications. It features a primary current rating of 300 A and a secondary output of 5 A, establishing a turns ratio of 300:5. The device operates within a frequency range of 50 Hz to 60 Hz and supports a maximum voltage of 600 V AC. Physical dimensions include a height of 84 mm, a length of 57.5 mm, and a width of 38.5 mm. It utilizes wire leads for termination and employs a free-hanging installation style. The unit accommodates a conductor bore diameter of 36 mm.
Feature Summary
- Split-core design allows for non-intrusive installation around existing busbars or cables without disconnecting the circuit.
- Provides accurate current sensing with a standard 5 A secondary output compatible with industrial power analyzers.
- Free-hanging mounting style facilitates flexible integration into various electrical panel configurations.
Applications
- Integration with multi-channel power analyzers for energy monitoring
- Industrial electrical distribution system monitoring
- Current sensing in commercial building management systems
Procurement Notes
Verify component authenticity through authorized Carlo Gavazzi distributors or verified electronic component suppliers. Confirm that the received unit matches the specific part number CTA6X300A5A, including the correct 300:5 ratio and 36 mm bore size. Check for physical integrity of the split core mechanism and wire leads prior to installation. Ensure compliance with local electrical safety standards and operational temperature ranges specified in the official datasheet.
Selection Notes
Select this model when a 300 A primary current capacity is required for split-core current measurement. The 36 mm bore diameter must accommodate the specific cable or busbar size in the application. This unit is suitable for 50/60 Hz systems requiring a 5 A secondary signal. Consider alternative models such as CTA6X200A5A or CTA6X500A5A if the primary current load differs significantly from 300 A.
Part Context
The CTA6X300A5A belongs to the Carlo Gavazzi CTA series of split-core current transformers. These devices are engineered specifically to interface with power analyzers and metering equipment. The series offers various primary current ratings and bore sizes to suit different industrial monitoring requirements while maintaining consistent secondary output characteristics.
Replacement Considerations
Direct substitutes within the same series include CTA6X200A5A (200 A) and CTA6X500A5A (500 A), provided the primary current rating aligns with the application needs. Verify that any replacement maintains the 300:5 ratio and 36 mm bore dimension for mechanical compatibility.
