CR5RL-501

Overview

The CR5RL-501 is a current sense transformer manufactured by CR Magnetics Inc., designed for in-line monitoring applications. It features a primary current rating of 500 A and a secondary output of 5 A, establishing a 500:5 current ratio. The device operates within a frequency range of 50 Hz to 400 Hz. Physically, it utilizes a free-hanging mounting style with a maximum seated height of 1.098 inches (27.90 mm). This component serves as a robust solution for high-current measurement tasks requiring electrical isolation between the primary circuit and sensing equipment.

Feature Summary

• Provides electrical isolation for high-current measurement via a 500:5 transformation ratio
• Supports in-line installation with a free-hanging mechanical configuration
• Operates effectively across a frequency spectrum from 50 Hz to 400 Hz

Applications

• High-current power system monitoring
• Industrial motor control feedback loops
• Power quality analysis equipment

Procurement Notes

Verify that the specific order matches the CR5RL-501 designation to ensure the correct 500 A primary rating and 500:5 ratio are received. Confirm that the application environment remains within the specified 50 Hz to 400 Hz operational frequency range. Check physical clearance requirements against the 1.098 inch maximum seated height to ensure compatibility with the intended free-hanging installation method.

Selection Notes

Select this component when precise measurement of currents up to 500 A is required without direct galvanic connection to the load. The 500:5 ratio allows standard 5 A rated instruments to interface safely with high-power circuits. Ensure the operating frequency aligns with the 50-400 Hz specification. Consider the physical dimensions and free-hanging form factor during mechanical design integration.

Part Context

This part belongs to the CR Magnetics current sense transformer family, which specializes in isolated measurement solutions. These transformers are engineered to provide accurate signal replication while maintaining safety barriers between high-voltage primary sides and low-voltage secondary sensing circuits. The series supports various current ratings tailored for different industrial power levels.
