CR7RL-152

Overview

The CR7RL-152 is a commercial class AC current sense transformer manufactured by CR Magnetics Inc. It features a donut-style core with a 2.5-inch inner diameter, designed for free-hanging in-line installation. The device operates within a frequency range of 50Hz to 400Hz and supports an input current range of 0 to 1500 AAC. It provides a proportional output signal for monitoring applications.

Feature Summary

• Donut-style core design for through-conductor mounting
• Free-hanging in-line installation capability
• Wide frequency operation from 50Hz to 400Hz
• High-capacity input handling up to 1.5 kA

Applications

• Industrial power monitoring systems
• Electrical panel current sensing
• Commercial grade AC circuit protection interfaces
• Power quality measurement equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct termination style and lead length specifications. Confirm that the required input current range aligns with the 1.5 kA rating before procurement. Cross-reference the physical dimensions, specifically the 2.5-inch ID, with the installation space constraints to ensure mechanical compatibility.

Selection Notes

Select this component when high-current AC sensing is required without breaking the primary conductor. The donut form factor allows for easy retrofitting into existing busbars or large cables. Ensure the operating frequency falls within the 50Hz to 400Hz range. Consider the free-hanging mounting style if bracketed installation is not feasible in the target enclosure layout.

Part Context

This part belongs to the CR7RL series of commercial-grade current transformers from CR Magnetics Inc. The series is characterized by robust construction for industrial environments. Similar models in the lineup may offer different input ranges or core diameters, but share the same fundamental in-line sensing architecture and frequency response characteristics.

Replacement Considerations

Direct substitutes include the CR7ARL-152, which shares identical electrical ratings and form factor. Verify that any alternative model maintains the 2.5-inch inner diameter and 1.5 kA input capacity to ensure functional equivalence in the existing assembly.
