Overview
The CR5SFT-101 is a current sense transformer manufactured by CR Magnetics Inc., designed for commercial-grade applications. It features a chassis mount configuration with a primary current rating of 100 A and a secondary output range of 0 to 5 A AC. The device operates within a frequency range of 50 Hz to 400 Hz. Physical dimensions are specified as 3.780 inches in length by 2.150 inches in width (96.00 mm x 54.60 mm). The unit utilizes an 8-32 terminal termination style and has an inner diameter of 1.56 inches, suitable for direct bus bar integration.
Feature Summary
- Chassis mount design for secure installation on panels or enclosures
- High current capacity supporting up to 100 A primary input
- Standardized 100:5 current ratio for compatible signal processing
Applications
- Commercial power monitoring systems
- Industrial motor control circuits
- Electrical distribution panel metering
Procurement Notes
Verify the specific datasheet version from CR Magnetics Inc. to confirm mechanical tolerances and insulation ratings. Ensure the mounting surface accommodates the chassis footprint and that the bus bar fits within the 1.56-inch inner diameter. Confirm that the operating frequency remains within the 50 Hz to 400 Hz specification for accurate signal transformation.
Selection Notes
Select this component when a robust, high-current sensing solution is required for frequencies up to 400 Hz. The chassis mount style is ideal for fixed installations where space efficiency and thermal stability are priorities. Consider the 100 A rating against peak load requirements to ensure the transformer does not saturate during transient conditions.
Part Context
This part belongs to the CR5SFT family of current sense transformers from CR Magnetics Inc. The series offers various current ratings tailored for different power levels. The CR5SFT-101 specifically addresses the 100 A requirement, providing a standardized interface for industrial and commercial power management applications requiring reliable current feedback.
Replacement Considerations
Direct substitutes include other models within the CR Magnetics CR5SFT series with matching current ratios. Verify mechanical dimensions and terminal configurations before replacing to ensure compatibility with existing mounting hardware and circuit connections.
