CR2DARL-201

Overview

The CR2DARL-201 is an AC current transformer manufactured by CR Magnetics Inc., designed for non-invasive current sensing applications. It features a donut-style solid core construction with a 1.00-inch inner diameter, allowing it to be installed around existing conductors without circuit interruption. The device operates within an input range of 0 to 200 Amperes AC and provides a corresponding output range of 0 to 5 Amperes AC, establishing a precise 100:5 current transformation ratio. This component is equipped with two 2-foot long 16 AWG fly leads for convenient electrical connection to downstream measurement or control equipment.

Feature Summary

• Non-invasive donut-style design enables installation around existing busbars or cables without breaking the primary circuit.
• Provides accurate current monitoring through a standard 100:5 transformation ratio suitable for metering interfaces.
• Includes integrated 2-foot 16 AWG fly leads to simplify wiring connections to secondary circuits.

Applications

• ANSI compliant electrical metering systems
• Industrial motor protection circuits
• Power distribution panel monitoring

Procurement Notes

Verify that the required conductor diameter fits within the specified 1.00-inch inner diameter before ordering. Confirm that the secondary load impedance remains compatible with the 5A output rating to maintain accuracy. Ensure the application voltage does not exceed the transformer's isolation ratings. Cross-reference the specific lead length requirements against the provided 2-foot specification to avoid field modification issues during installation.

Selection Notes

Select this model when a robust, non-invasive solution is needed for high-current AC monitoring up to 200A. The 100:5 ratio is ideal for interfacing with standard industrial ammeters or relay inputs. Consider the physical size constraints of the installation area relative to the core dimensions. Evaluate the need for fly leads versus direct PCB mounting options based on the system architecture and available space for wiring management.

Part Context

This component belongs to the CR Magnetics line of current sense transformers, which are engineered for reliable performance in demanding electrical environments.
