5RL-501

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc. 5RL-501 is a solid-core current transformer designed for indoor electrical measurement applications. It features a primary current rating of 500 A and a secondary output of 5 A, providing a precise 500:5 turns ratio. The unit operates within a frequency range of 50 Hz to 400 Hz and is rated for 600 V indoor use. It complies with ANSI standards and holds UL and CSA approvals. The transformer offers 1% metering accuracy and supports a 20 VA burden, ensuring reliable performance in building automation and industrial monitoring systems.

Current Sense Transformers Feature Summary

• Provides proportional low-amperage current output relative to line current for accurate sensing
• Constructed as a non-invasive solid-core design for easy installation around conductors
• Complies with ANSI standards and carries UL and CSA safety certifications

Current Sense Transformers Applications

• Building automation systems requiring precise current monitoring
• Industrial electrical metering and protection circuits
• Indoor power distribution panels for load management

Current Sense Transformers Procurement Notes

Verify that the required operating frequency falls within the 50 Hz to 400 Hz range specified for this component. Confirm that the system burden does not exceed the 20 VA rating to maintain the stated 1% accuracy. Ensure the installation environment is indoor, as the unit is rated for 600 V indoor use only. Cross-check physical dimensions against panel cutouts if mounting constraints are critical.

Current Sense Transformers Selection Notes

Select the 5RL-501 when a 500 A primary current rating and 5 A secondary output are required for metering purposes. This model is suitable for applications needing ANSI compliance and UL/CSA certification. Consider alternative ratios if the primary current exceeds 500 A or if different accuracy classes are mandated by specific regulatory standards.

Current Sense Transformers Part Context

The 5RL series represents a line of solid-core current transformers from Sifam Tinsley, formerly GE ITI. These devices are engineered for high-reliability current sensing in commercial and industrial settings. The 5RL-501 specifically addresses the need for standardized, certified measurement solutions in 600 V class indoor electrical infrastructure.

Current Sense Transformers Replacement Considerations

Direct substitutes include other 500:5 ratio solid-core transformers meeting ANSI and UL standards. Verify compatibility regarding physical footprint, terminal configuration, and burden capacity before swapping.
