7SHT-401

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc. 7SHT-401 is a non-ANSI rated window type current transformer designed for panel mounting applications. It features a turns ratio of 400:5 and operates within a frequency range of 50Hz to 400Hz. The unit provides an accuracy class of Class 1 with a power rating of 15 VA. It has a window inner diameter of 63.5 mm and supports an insulation level of 600V with a 10kV BIL full wave rating.

Current Sense Transformers Feature Summary

• Window type construction for easy installation around conductors
• Class 1 accuracy rating for precise current sensing
• Broad frequency operation from 50Hz to 400Hz

Current Sense Transformers Applications

• Integration with ammeters for current monitoring
• Connection to watt meters for power measurement
• Cross current compensation systems

Current Sense Transformers Procurement Notes

Verify the specific requirement for non-ANSI rating against project standards, as ANSI-rated alternatives like the 19SHT-401 exist. Confirm that the 63.5 mm window dimension accommodates the target conductor size. Ensure the 15 VA burden capacity matches the connected instrument load to maintain Class 1 accuracy within the specified 50Hz to 400Hz operational range.

Current Sense Transformers Selection Notes

Select this model when a non-ANSI rated transformer is acceptable and a 400:5 ratio is required. The 63.5 mm window size limits conductor compatibility compared to larger variants. Consider the 15 VA power rating for burden calculations. This component is suitable for panel-mounted instrumentation where standard insulation levels are sufficient.

Current Sense Transformers Part Context

The 7SHT-401 belongs to the Sifam Tinsley instrumentation line, which includes various analog and digital metering solutions. It serves as a signal transducer for electrical measurement systems. The manufacturer offers both ANSI and non-ANSI rated options, with this specific part targeting general industrial applications requiring reliable current transformation across varying frequencies.

Current Sense Transformers Replacement Considerations

The 19SHT-401 is an ANSI-rated alternative with similar specifications but a larger 108 mm window and 10 VA rating. Verify if ANSI compliance is mandatory before substitution.
