Overview
The CR2RL-101 is a non-invasive solid core current sense transformer manufactured by CR Magnetics Inc. It features a primary current rating of 100 A and a secondary output of 5 A, resulting in a 100:5 ratio. The device operates within a frequency range of 50 Hz to 400 Hz and maintains 1% accuracy at 60 Hz. It has a window diameter of 1.13 inches (28.7 mm) and overall dimensions of 2.461 inches in diameter by 1.051 inches in height. The unit includes 24-inch UL 1015 #16 AWG wire leads.
Feature Summary
- Non-invasive solid core design for through-conductor installation
- Epoxy resin secured core construction for durability
- UL recognized commercial grade classification
- Standard 5 Amp secondary output with long wire leads
Applications
- Commercial power monitoring systems
- Industrial motor control circuits
- Electrical panel metering
- Current sensing for protection relays
Procurement Notes
Verify the specific lead length and insulation type against project requirements before ordering. Confirm that the 100 A primary rating aligns with the maximum expected load current. Ensure the operating frequency falls within the 50-400 Hz specification. Check for UL recognition compliance if required by local electrical codes. Validate physical dimensions fit the available panel space.
Selection Notes
Select this component when a robust, non-invasive solution for high-current measurement is needed. The 100:5 ratio is suitable for standard ammeter inputs. Consider the 1.13-inch window size to ensure the conductor fits. The epoxy-sealed core offers environmental protection compared to open-frame designs. Verify that the 5 Amp secondary burden does not exceed transformer limits.
Part Context
This part belongs to the CR2 series of current sense transformers from CR Magnetics Inc. The series provides various ratios and current ratings for different applications. The CR2RL-101 specifically targets commercial-grade applications requiring reliable current monitoring. It is designed for integration into electrical distribution equipment.
Replacement Considerations
Direct substitutes must match the 100:5 ratio, 100 A primary rating, and similar physical dimensions. Verify compatibility with existing mounting hardware and wiring configurations. Cross-reference accuracy classes and frequency ranges to ensure performance parity.
