2SHT-301

Overview

The Sifam Tinsley Instrumentation Inc 2SHT-301 is a non-ANSI rated window-type current transformer belonging to the Omega 30A series. It features a 300:5 turns ratio and an 8 VA burden rating with Class 1 accuracy. The unit has a 28.7 mm aperture for solid core conductors and operates within a frequency range of 50Hz to 400Hz.

Feature Summary

• Window-type design for non-invasive installation around solid core conductors
• Class 1 accuracy rating for precise current sensing applications
• Operates across a wide frequency spectrum from 50Hz to 400Hz

Applications

• Industrial power monitoring systems
• Electrical panel metering circuits
• Current sensing for protection relays

Procurement Notes

Verify that the application requires a non-ANSI rated component, as this model does not meet ANSI standards. Confirm the primary current matches the 300:5 ratio and the secondary load does not exceed the 8 VA rating. Ensure the conductor diameter fits within the 28.7 mm aperture before ordering.

Selection Notes

Select this model when a window-type configuration is required for existing busbars or cables. It is suitable for frequencies up to 400Hz, making it appropriate for variable frequency drive environments. Choose this over ANSI-rated models if specific industry standards do not mandate compliance.

Part Context

This component is part of the Omega 30A series, designed for robust current transformation in industrial settings. Sifam Tinsley Instrumentation Inc manufactures these devices to provide reliable signal isolation and scaling for measurement equipment.

Replacement Considerations

Direct substitutes must match the 300:5 ratio, 28.7 mm aperture, and 8 VA burden. Verify frequency compatibility up to 400Hz and ensure the replacement maintains Class 1 accuracy for equivalent performance.
