5RL-151

Overview

The Instrument Transformer 5RL-151 is a single-phase current transformer designed for indoor applications. It features a 150:5 turns ratio with an input current rating of 150A. The device operates within a frequency range of 50Hz to 400Hz and supports panel mounting configurations. It provides 600V insulation class capability and includes a 10kV Basic Impulse Insulation Level (BIL). The unit utilizes a non-ANSI rated construction with a free-hanging or in-line design suitable for direct wire insertion.

Feature Summary

Provides accurate current sensing for metering and protection circuits
Supports wide frequency operation from 50Hz to 400Hz
Features high insulation strength with 10kV BIL rating
Designed for easy installation via panel or inline mounting

Applications

Connection to ammeters for current measurement
Integration with wattmeters for power monitoring
Cross-current compensation systems
Indoor electrical distribution panels

Procurement Notes

Verify the specific manufacturer designation, as sources cite both Instrument Transformers Inc and GE ITI divisions. Confirm the exact mounting style required, as listings vary between panel mount and free-hanging in-line configurations. Ensure the application voltage does not exceed the 600V rating and that the frequency falls within the 50-400Hz operational window.

Selection Notes

Select this component when a 150:5 ratio is required for single-phase indoor systems. Consider the 10kV BIL rating for environments requiring robust impulse insulation. Evaluate the physical dimensions against available panel space, noting the 8x8x6 inch footprint. Ensure compatibility with downstream instruments accepting 5A secondary currents.

Part Context

This model belongs to the 5RL series of instrument transformers. It is historically associated with Instrument Transformers Inc, which was later acquired by GE Industrial Systems. The product line focuses on general-purpose current sensing for industrial and commercial electrical infrastructure.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Cross-reference part numbers such as IT51CT15546 for potential equivalent sourcing. Verify mechanical fit and electrical ratings before substituting with generic 150:5 current transformers.
