Overview
The CR7RL-101 is a current sense transformer manufactured by CR Magnetics Inc., designed for commercial class applications. It features a rated primary current of 100 A and operates within a frequency range of 50 Hz to 400 Hz. The device utilizes a free-hanging in-line mounting style, allowing for direct integration into power lines without additional brackets. This configuration supports straightforward installation in systems requiring reliable AC current monitoring.
Feature Summary
- Commercial grade construction suitable for general industrial monitoring
- Free-hanging in-line design for direct circuit integration
- Operational capability across 50 Hz to 400 Hz frequency spectrum
Applications
- AC current monitoring in industrial power distribution systems
- Commercial electrical equipment sensing applications
- Power quality analysis within specified frequency ranges
Procurement Notes
Verify the specific datasheet version for the CR7RL-101 to confirm exact secondary output specifications and burden requirements. Ensure the application environment matches the commercial class rating rather than ANSI metering standards. Confirm that the 100 A primary rating aligns with the maximum expected load currents to prevent saturation or damage during peak operations.
Selection Notes
Select this component when a robust, commercially rated current transformer is required for frequencies between 50 Hz and 400 Hz. The in-line form factor is ideal for applications where space constraints preclude split-core designs but direct wiring is feasible. Consider the thermal limits associated with continuous 100 A operation when designing the surrounding enclosure.
Part Context
This model belongs to the CR Magnetics line of instrumentation-grade electrical current transformers. These devices are available in both commercial and ANSI metering classes, offering versatile solutions for various sensing needs. The CR series typically emphasizes durability and accuracy for standard industrial environments.
