7RL-162

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc. model 7RL-162 is a panel-mount current transformer designed for electrical monitoring applications. It features a window-type construction with a turns ratio of 1600:5 and supports frequency ranges from 50Hz to 400Hz. The unit has an accuracy class of Class 1 and a power rating of 45VA. It weighs approximately 2.00 lbs (0.91 kg) and is constructed as a non-ANSI rated device suitable for free-hanging or inline installation.

Current Sense Transformers Feature Summary

• Window-type construction for non-invasive current sensing
• High accuracy Class 1 performance
• Wide frequency range support up to 400Hz

Current Sense Transformers Applications

• Electrical panel monitoring systems
• Industrial power distribution measurement
• Current sensing in variable frequency drives

Current Sense Transformers Procurement Notes

Verify the specific accuracy class and power rating requirements against your system design, as sources indicate variations between Class 1/Class 2 and 45VA/2.5VA. Confirm that the non-ANSI rated status aligns with your regulatory compliance needs. Ensure the 1600:5 ratio matches your primary current input. Check physical dimensions and mounting style compatibility with existing panel cutouts before ordering.

Current Sense Transformers Selection Notes

Select this component when a high-accuracy current transformer is required for frequencies up to 400Hz. The 1600:5 ratio suits high-current applications. Consider the non-ANSI rating if standard industrial certification is not mandatory. Compare weight and size constraints against alternative models like the 7RL-101 if space is limited.

Current Sense Transformers Part Context

This part belongs to the Sifam Tinsley current transformer line, which includes various ratios and accuracy classes. It is distinct from their metering products like the Beta 90 series. The 7RL-162 specifically targets high-current measurement scenarios requiring precise transformation ratios.

Current Sense Transformers Replacement Considerations

The 7RL-101 is a documented substitute within the same product family, offering similar frequency ranges but potentially different accuracy and power ratings.
