CR8350-1000

Overview

The CR8350-1000 is a current sense transformer manufactured by CR Magnetics Inc., designed for through-hole mounting. It features a non-invasive solid core construction with PC pin termination. The device supports a primary rated current of 100 A and operates within a frequency range of 20 Hz to 1 kHz. It provides a current ratio of 1000:1 and exhibits a DC resistance of 22 Ohms. The component measures 1.024 inches in length, 0.670 inches in width, and has a maximum installation height of 1.102 inches.

Feature Summary

• Non-invasive solid core design for isolated measurement without circuit interruption
• Through-hole mounting configuration with PC pin termination for PCB integration
• Epoxy encapsulated construction providing ruggedness and environmental protection

Applications

• Remote monitoring of electrical loads
• Input signal provision for electrical control systems
• Detection of open heater elements
• Phase loss indication
• Motor operation monitoring

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct specifications. Confirm that the required current rating and frequency range align with the application requirements before procurement. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the through-hole package dimensions fit the target printed circuit board layout constraints.

Selection Notes

Select this component when a non-invasive current sensing solution is required for AC signals between 20 Hz and 1 kHz. The 100 A primary rating and 1000:1 ratio determine the secondary output characteristics. Consider the physical size and through-hole mounting style for mechanical integration. Verify that the 22 Ohm DC resistance meets the burden resistor requirements of the downstream circuitry.

Part Context

This component belongs to the CR8350 series of electrical current transformers from CR Magnetics Inc. The series includes variants available in both wire lead and printed circuit board styles. The CR8350-1000 specifically denotes the 100 A rated model within this family, utilizing a solid core design distinct from split-core alternatives offered by the manufacturer.

Replacement Considerations

Direct substitutes within the same series include models with different primary current ratings such as CR8350-2500-N. Cross-model replacement requires verification of matching current ratios, frequency ranges, and physical mounting dimensions to ensure functional compatibility.
