2RL-101

Overview

The Sifam Tinsley Instrumentation Inc. 2RL-101 is a non-invasive solid core AC current transformer designed for panel mounting applications. It features a primary current rating of 100 A and a secondary output of 5 A, providing a standard signal interface for measurement devices. The unit operates within a frequency range of 50 Hz to 400 Hz and maintains an accuracy class of 1 with a burden capacity of 2 VA. Constructed with a sensing window diameter of 26.7 mm (1.05 inches), it utilizes two 24-inch 16 AWG lead wires for connection. This component complies with ANSI standards for current transformers.

Feature Summary

• Non-invasive solid core design allows installation without breaking the primary circuit.
• Provides accurate current transformation from high primary currents to low secondary signals for metering.
• Complies with ANSI standards ensuring reliability in industrial electrical environments.

Applications

• Panel-mounted AC current monitoring systems
• Industrial power distribution measurement
• Electrical protection relay input circuits

Procurement Notes

Verify that the required primary current matches the 100 A specification and that the system frequency falls within the 50 Hz to 400 Hz operational range. Confirm that the connected burden does not exceed the 2 VA rating to maintain Class 1 accuracy. Ensure the 26.7 mm window accommodates the conductor size and that the 24-inch leads suit the panel layout requirements.

Selection Notes

Select this model when a non-invasive solution is required for 100 A AC circuits. It is suitable for applications needing a 5 A secondary output compatible with standard ammeters or relays. Consider the physical dimensions and lead length during integration. Alternative models may be necessary if higher primary ratings or different accuracy classes are required.

Part Context

The 2RL-101 belongs to the Omega 30 series of current transformers from Sifam Tinsley. This series focuses on robust, ANSI-compliant components for industrial instrumentation. The product line emphasizes durability and precise measurement capabilities for various electrical monitoring tasks across different frequency ranges.

Replacement Considerations

Direct substitutes must match the 100:5 ratio, 26.7 mm window, and ANSI compliance. Verify compatibility with existing panel cutouts and wiring configurations before switching manufacturers.
