19SHT 152

Overview

The Sifam Tinsley Instrumentation Inc. part number 19SHT 152 is an Omega 30 series current transformer designed for industrial electrical measurement applications. This component operates within a frequency range of 50Hz to 400Hz and features a non-invasive solid core construction. It provides a primary-to-secondary current ratio of 1500:5, facilitating the connection of high-current circuits to standard low-range measuring instruments. The unit is engineered for chassis or panel mounting, ensuring secure installation in control panels. Key physical specifications include a 4.25-inch inner diameter aperture, accommodating conductors up to that dimension. The device adheres to ANSI standards for current transformers, ensuring compatibility with established industrial testing and monitoring systems.

Feature Summary

• Non-invasive solid core design for safe conductor insertion without circuit interruption
• High current transformation ratio of 1500:5 for accurate metering of large loads
• Wide frequency operational range supporting 50Hz to 400Hz power systems
• Robust chassis mount configuration with integrated terminal connections

Applications

• Industrial power distribution panel monitoring
• Electrical load measurement in manufacturing facilities
• Integration with analog or digital ammeters for current tracking
• Energy management systems requiring high-capacity current sensing

Procurement Notes

Verify the specific ordering suffix and accessory requirements before purchase. Confirm that the 4.25-inch inner diameter matches the conductor size in your application. Ensure the mounting method aligns with your panel design constraints. Check for any required terminal blocks or hardware not included in the base unit. Validate compliance with local electrical codes for the intended installation environment.

Selection Notes

Select this model when monitoring currents up to 1500A is required. The 1500:5 ratio suits applications where standard 5A secondary meters are used. Consider the 4.25-inch bore size for busbars or thick cables. The Omega 30 series offers durability for harsh industrial environments. Ensure the operating frequency falls within the 50-400Hz specification for optimal accuracy.

Part Context

This component belongs to the Omega 30 series from Sifam Tinsley, a line known for precision electrical instrumentation. The series includes various current transformers tailored for different current ranges and mounting styles. The 19SHT 152 specifically addresses high-current measurement needs. It complements other Sifam Tinsley products like analog panel meters and voltage indicators, forming complete measurement solutions for industrial control panels.

Replacement Considerations

Direct substitutes may include other ANSI-compliant current transformers with identical 1500:5 ratios and similar bore sizes. Verify mechanical dimensions and mounting hole patterns for compatibility. Ensure the replacement unit supports the same 50-400Hz frequency range. Check if terminal configurations match existing wiring setups.
