CR8349-1000

Overview

The CR8349-1000 is a general-purpose vertical PCB current transformer from the CR8300 series, manufactured by CR Magnetics Inc. It features a solid core design with a 1000:1 turns ratio and supports a maximum continuous primary current of 50 A. The device operates within a frequency range of 20 Hz to 1 kHz and has a DC resistance of 32 ohms. Designed for through-hole mounting, it utilizes PC pin termination. The component is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Non-invasive solid core construction for isolated current measurement
• Vertical PCB mounting configuration with PC pin termination
• High isolation voltage capability for electrical safety

Applications

• Remote monitoring of electrical loads
• Input signal conditioning for electrical control systems
• Detection of open heater elements or phase loss
• Motor operation monitoring

Procurement Notes

Verify the specific suffix against procurement requirements. The CR8349-1000-N variant specifies a 32-ohm DC resistance, whereas the base CR8349-1000 may differ in this parameter. Confirm that the solid core design aligns with installation constraints, as split-core alternatives exist within the manufacturer's portfolio. Ensure the 50 A rating meets system peak demands.

Selection Notes

Select this component for applications requiring non-invasive AC current sensing with high isolation. The 1000:1 ratio provides a proportional output suitable for resistive burden connections. Verify that the operating frequency falls within the 20 Hz to 1 kHz range. Consider the physical dimensions of 26.00 mm x 17.00 mm for PCB layout compatibility.
