2RL-500

Overview

The Sifam Tinsley 2RL-500 is a solid core AC current transformer designed for non-ANSI rated applications. It features a primary current rating of 50 A and a secondary output of 5 A, providing a 50:5 transformation ratio. The device operates within a frequency range of 50 Hz to 400 Hz and maintains an accuracy class of 2 with ±3% tolerance. It includes a sensing window diameter of 1.05 inches (25.4 mm) and is equipped with two 24-inch 16 AWG lead wires. The unit supports a power rating of 1.5 VA and offers insulation up to 600 Volts with 10 kV BIL.

Feature Summary

• Solid core construction for free-hanging or in-line installation
• Wide frequency operation from 50 Hz to 400 Hz
• Integrated 24-inch 16 AWG lead wires for direct connection

Applications

• Industrial current monitoring systems
• Power distribution circuit analysis
• Electrical testing equipment integration

Procurement Notes

Verify that the application requires a non-ANSI rated component, as this model does not meet ANSI standards. Confirm that the operating frequency falls within the 50 Hz to 400 Hz range and that the 50 A primary current capacity aligns with the circuit requirements. Ensure the 1.05-inch window diameter accommodates the conductor size.

Selection Notes

Select this model when a robust solid core transformer is needed for frequencies up to 400 Hz. The 50:5 ratio suits standard metering inputs. Consider the physical dimensions of the 1.05-inch window and the length of the attached leads during panel layout planning to ensure adequate clearance and routing space.

Part Context

This component belongs to the Omega series of current transformers from Sifam Tinsley Instrumentation Inc. It is engineered for general-purpose electrical measurement tasks where high-frequency capability beyond standard 60 Hz is required. The design emphasizes durability through its solid core architecture.
