CRZ8410-1K4W

Overview

The CRZ8410-1K4W is a zero sequence current sense transformer manufactured by CR Magnetics Inc. It features a turns ratio of 1:1000:4 and operates within a frequency range of 50Hz to 60Hz. The component has a maximum primary side DC resistance (DCR) of 57Ω. It utilizes a free hanging in-line mounting type with dimensions of 1.083 inches in length and 0.941 inches in width.

Feature Summary

• Zero sequence current sensing capability for accurate phase imbalance detection
• Free hanging in-line mounting design for flexible integration
• Optimized for low-frequency power line applications

Applications

• Ground fault detection systems
• Electrical protection relays
• Power quality monitoring equipment

Procurement Notes

Verify the specific ordering suffix and manufacturer documentation to ensure compliance with required electrical specifications and mechanical dimensions. Confirm that the zero sequence configuration matches the intended circuit topology before procurement to avoid integration errors.

Selection Notes

Select this component when precise zero sequence current measurement is required at standard power frequencies. Ensure the system accommodates the specified physical dimensions and in-line mounting style. Validate that the 57Ω DCR constraint aligns with the source impedance requirements of the connected measurement circuitry.

Part Context

This part belongs to the CR Magnetics current transformer family, specifically designed for industrial power monitoring. It serves as a specialized sensor for detecting residual currents in three-phase systems, distinguishing it from standard single-ratio current transformers used for general load monitoring.

Replacement Considerations
