2SHT-121

Overview

The Sifam Tinsley Instrumentation Inc. model 2SHT-121 is an ANSI standard current sense transformer designed for panel or chassis mounting applications. It features a primary-to-secondary turns ratio of 120:5, converting high primary currents to a standardized 5A secondary output. The device operates within a frequency range of 50Hz to 400Hz, making it suitable for various industrial power monitoring scenarios. Key physical specifications include a 1.13-inch inner diameter and terminal connection configuration, ensuring compatibility with standard busbar installations in electrical distribution systems.

Feature Summary

• ANSI standard compliance for reliable current sensing
• Terminal connection configuration for secure wiring
• Panel or chassis mount design for stable installation

Applications

• Industrial power distribution monitoring
• Electrical metering systems
• Current sensing in AC power circuits

Procurement Notes

Verify the specific mounting style (panel vs. chassis) required for your application before ordering. Confirm that the 120:5 ratio aligns with your metering equipment input requirements. Ensure the operating frequency range of 50Hz to 400Hz matches your system's power frequency. Check mechanical dimensions against available space constraints.

Selection Notes

Select this component when an ANSI-compliant current transformer is needed for panel-mounted installations. Consider the 120:5 ratio to ensure compatibility with downstream 5A-rated measuring instruments. Evaluate the 1.13-inch inner diameter to verify fitment with existing busbars or conductors. Assess the 50-400Hz operational bandwidth against your system's harmonic content and frequency stability.

Part Context

This part belongs to the Omega 30A series of current transformers from Sifam Tinsley. The series is characterized by robust construction and adherence to international standards for electrical measurement. These transformers are engineered for precision in demanding industrial environments, providing accurate current transformation for protection and metering purposes.

Replacement Considerations

Direct substitutes must match the 120:5 ratio, 5A secondary output, and ANSI classification. Verify mechanical compatibility regarding the 1.13-inch ID and mounting footprint. Cross-reference frequency ranges to ensure no degradation in performance at 50Hz or 400Hz.
