2SHT-151

Overview

The Sifam Tinsley Instrumentation Inc. model 2SHT-151 is a panel-mount current transformer designed for electrical measurement applications. It features a window-type construction with an internal diameter of 28.7 mm (1.13 inches). The device operates within a frequency range of 50 Hz to 400 Hz and provides a turns ratio of 150:5. It is rated at 4 VA burden capacity and meets Class 1 accuracy standards.

Feature Summary

• Window-type design for through-conductor installation
• Operates across 50 Hz to 400 Hz frequency spectrum
• Provides 150:5 step-down transformation ratio
• Class 1 accuracy rating for measurement precision

Applications

• Electrical panel metering systems
• Power monitoring equipment integration
• Industrial process control instrumentation

Procurement Notes

Verify the specific accuracy class requirements against the Class 1 rating. Confirm that the primary conductor fits within the 28.7 mm window aperture. Ensure the operating frequency aligns with the 50–400 Hz specification. Check if ANSI or non-ANSI compliance is required for the target installation environment.

Selection Notes

Select this component when a 150:5 ratio is necessary for current scaling. The 4 VA rating must support the connected burden load. Consider the panel mounting style for enclosure integration. Verify thermal limits if ambient temperatures exceed standard ranges.

Part Context

This part belongs to the Sifam Tinsley current transformer lineup, specialized for analog and digital panel instruments. It complements their range of ammeters and power meters by providing isolated current sensing. The window design allows for retrofitting existing busbars without breaking the circuit.
