2SFT-1250

Overview

The Sifam Tinsley Instrumentation Inc. model 2SFT-1250 is an Omega series current transformer designed for panel mounting applications. It features a primary current rating of 30A and a secondary output of 5A, with a turns ratio of 125:5. The device supports operating frequencies ranging from 50Hz to 400Hz. It utilizes a foot mount installation type with terminal connections and has an inner diameter of 1.13 inches. This component complies with ANSI standards for electrical measurement instrumentation.

Feature Summary

• Provides accurate current transformation for electrical monitoring systems
• Designed for secure panel mounting with integrated terminals
• Supports wide frequency range operation for versatile industrial use

Applications

• Industrial power distribution panels
• Electrical metering equipment integration
• Current monitoring in commercial facilities

Procurement Notes

Verify the specific manufacturing date code and batch number against project requirements to ensure compatibility with existing infrastructure. Confirm that the 1.13-inch inner diameter matches the conductor size intended for insertion. Ensure that the foot mount configuration aligns with the available panel space and mounting hardware specifications before finalizing the order.

Selection Notes

Select this model when a 30A primary current rating and 5A secondary output are required for panel-mounted installations. The 125:5 ratio suits applications needing precise step-down conversion for standard ammeters or relays. Consider the 50-400Hz frequency range if operating in environments with variable frequency drives or non-standard grid frequencies.
