5RL-751

Overview

The Sifam Tinsley Instrumentation Inc. model 5RL-751 is a current sense transformer designed for panel mounting applications. It operates within a frequency range of 50 Hz to 400 Hz and features a turns ratio of 750:5. The unit utilizes an ANSI standard configuration with a 1.56-inch inner diameter and a lead length of 24 inches, incorporating a D-nut for secure installation.

Feature Summary

• Supports wide frequency operation from 50 Hz to 400 Hz
• Provides precise 750:5 current transformation ratio
• Features robust ANSI standard construction for industrial reliability

Applications

• Panel-mounted electrical monitoring systems
• Industrial power distribution measurement
• Current sensing in variable frequency drive circuits

Procurement Notes

Verify the specific physical dimensions, particularly the 1.56-inch ID and 24-inch lead length, against panel cutout requirements. Confirm that the operating environment remains within the 50 Hz to 400 Hz frequency range. Ensure compatibility with the 750:5 ratio for downstream metering or protection devices before finalizing procurement.

Selection Notes

Select this component when a dedicated current transformer is required for frequencies up to 400 Hz. The 750:5 ratio suits applications needing step-down current for standard instrumentation. Consider the panel mount style and D-nut fixation method for vibration-resistant installations in industrial settings.
