2SFT-250

Overview

The Sifam Tinsley Instrumentation Inc 2SFT-250 is a solid core AC current transformer designed for panel mounting. It features a primary current rating of 25 A and a secondary output of 5 A, with a sensing window diameter of 1.13 inches (26.70 mm). The device provides an accuracy class of ±5% and operates within a frequency range of 50 Hz to 400 Hz. It utilizes an 8-32 terminal stud for electrical connections.

Feature Summary

Non-invasive solid core design for through-conductor measurement
Compatible with standard panel mounting configurations
Supports wide frequency operation from 50 Hz to 400 Hz

Applications

Industrial power monitoring systems
Electrical distribution panels
Energy management metering

Procurement Notes

Verify the specific datasheet version for the 2SFT-250 to confirm mechanical dimensions and terminal specifications match your panel cutout requirements. Ensure the load impedance connected to the secondary winding remains within the transformer's rated burden limits to maintain the specified ±5% accuracy. Confirm that the operating frequency range aligns with your system's nominal frequency.

Selection Notes

Select this model when a non-invasive solution is required for currents up to 25 A. The solid core design simplifies installation by allowing the conductor to pass through the center without disconnection. Consider the ±5% accuracy tolerance against your measurement precision needs. The 5 A secondary output is standard for compatibility with most industrial ammeters and relay inputs.

Part Context

This component belongs to the general category of AC current transformers manufactured by Sifam Tinsley. It serves as a signal conditioning interface between high-current primary circuits and low-current secondary measurement devices. The product line focuses on providing reliable isolation and accurate current representation for industrial instrumentation applications.
