• Donut style design facilitating easy installation around conductors
• Integrated 2-foot 16AWG fly leads for direct connection

Applications

• Industrial power monitoring systems
• Electrical panel metering
• Utility distribution equipment

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct configuration. Confirm that the required ANSI metering class rating aligns with your system's precision requirements. Check physical dimensions and lead length specifications to ensure compatibility with existing panel layouts and wiring harnesses before finalizing procurement orders.

Selection Notes

Select this component when high-accuracy metering is required for AC currents up to 100A. Ensure the operating frequency falls within the 50Hz to 400Hz range. Consider the 2.5-inch ID for conductor size compatibility. Verify that the 100:5 ratio matches downstream instrumentation inputs. Evaluate the free-hanging mounting option against available space constraints in the assembly.

Part Context

This model belongs to CR Magnetics' line of AC current transformers, which are widely used in industrial and utility sectors. The company specializes in sensors and transducers for power quality and control. This specific series emphasizes reliability and compliance with ANSI standards for metering applications, serving as a critical interface between high-current circuits and low-current measuring devices.

Replacement Considerations

Consult official substitution guides for equivalent models with matching ratios and accuracy classes. Verify dimensional compatibility for the 2.5-inch aperture. Ensure frequency response remains within 50Hz-400Hz. Cross-reference lead lengths and termination types to maintain wiring integrity without modification.
