2SFT-800

Overview

The Sifam Tinsley Instrumentation Inc. 2SFT-800 is an 80 A current sense transformer designed for panel mounting applications. It features a primary-to-secondary current ratio of 80:5 and operates within a frequency range of 50 Hz to 400 Hz. This component functions as a non-invasive measurement device, allowing for the monitoring of electrical currents without breaking the circuit continuity.

Feature Summary

• Provides isolated secondary current output proportional to primary load
• Supports wide frequency operation from 50 Hz to 400 Hz
• Enables non-invasive solid core current sensing

Applications

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

Procurement Notes

Verify the specific datasheet requirements for burden resistance and accuracy class before integration. Confirm that the operating frequency range aligns with the system's signal characteristics. Ensure the panel mounting configuration matches the physical installation constraints of the target equipment.

Selection Notes

Select this model when an 80 A primary rating and 5 A secondary output are required. Consider the 50 Hz to 400 Hz operational bandwidth for compatibility with variable frequency drives or standard utility frequencies. Evaluate the need for non-invasive installation versus split-core alternatives based on existing wiring infrastructure.
