The Sifam Tinsley 2SHT-750 is an Omega 30A ANSI-rated current transformer designed for precise current sensing applications. It features a 75:5 current ratio, supporting primary currents up to 75 A with a secondary output of 5 A. The unit operates within a frequency range of 50 Hz to 400 Hz and has a power rating of 2 VA. Key physical specifications include a window diameter of 28.7 mm (1.13 inches) and a seated height of 23.87 mm (0.940 inches). It utilizes terminal connections and bracket mounting for secure installation.
Verify the specific mounting bracket requirements and terminal connection types against the installation diagram before procurement. Confirm that the system frequency falls within the 50 Hz to 400 Hz operational range. Ensure the load impedance does not exceed the 2 VA power rating to maintain accuracy. Check for any specific ANSI certification documentation required by local regulatory standards.
Select this model when a 75:5 ratio is required for low-current AC measurement in high-frequency environments. Compare against non-ANSI rated alternatives if strict industry compliance is necessary. Consider the 28.7 mm window size to ensure compatibility with existing busbar or cable dimensions. Evaluate the bracket mount style against available panel space constraints.
This component belongs to the Omega 30A series of current transformers from Sifam Tinsley Instrumentation Inc. The series is characterized by ANSI ratings and robust construction for industrial instrumentation. It serves as a precision interface between high-current circuits and measuring devices, ensuring accurate signal transmission for monitoring and control applications.
Direct substitutes must match the 75:5 ratio, 28.7 mm window diameter, and ANSI certification. Verify mechanical mounting hole patterns and terminal configurations to ensure interchangeability without modification.
