Overview
The Sifam Tinsley Instrumentation Inc. model 19SHT 252 is an Omega 30 series current transformer designed for panel mounting with integrated terminals. It features a window-type construction with a 4.25-inch inner diameter and a 24-inch length, accommodating large busbars or cables. The device provides a 2500:5 current transformation ratio, suitable for high-current monitoring applications. It operates within a frequency range of 50Hz to 400Hz and complies with ANSI standards for electrical measurement accuracy.
Feature Summary
- Window-type design for non-invasive installation on solid core conductors
- Integrated foot mount configuration with built-in terminal connections
- ANSI rated performance ensuring compliance with industry measurement standards
Applications
- High-current electrical panel monitoring
- Industrial power distribution systems
- Electrical metering and protection circuits
Procurement Notes
Verify the specific terminal configuration and mounting hole dimensions against the physical panel layout before ordering. Confirm that the conductor size fits within the 4.25-inch aperture. Ensure the operating frequency falls within the specified 50Hz to 400Hz range for accurate signal output.
Selection Notes
Select this component when a robust, ANSI-compliant solution is required for currents up to 2500A primary. The integrated terminals simplify wiring compared to models requiring external burden resistors. Consider the physical depth and footprint to ensure adequate clearance in the switchgear enclosure.
Part Context
This unit belongs to the Omega 30 series, which represents a line of industrial-grade current transformers known for durability and precision. The series is widely utilized in heavy-duty environments where reliable current sensing is critical for system safety and operational efficiency.
Replacement Considerations
Direct substitutes must match the 2500:5 ratio, 4.25-inch ID, and ANSI rating. Verify mechanical compatibility with existing mounting brackets and terminal blocks to avoid retrofitting issues.
