19RL 801

Overview

The Sifam Tinsley Instrumentation Inc 19RL-801 is a solid core AC current transformer designed for non-invasive current sensing applications. It features an 800 A primary current rating and provides a 5 A secondary output, suitable for integration with ammeters or protective relays. The device utilizes a free-hanging in-line mounting configuration, allowing installation directly onto busbars without structural modification. It operates within a frequency range of 50 Hz to 400 Hz and maintains a measurement accuracy of ±1%. The unit includes two 24-inch long, 16 AWG lead wires for electrical connection.

Feature Summary

• Solid core construction enables direct insertion around conductors
• High precision measurement capability with ±1% accuracy
• Flexible wiring via extended 24-inch lead wires

Applications

• Industrial power distribution monitoring
• Electrical panel metering systems
• Protective relay input circuits

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct accuracy class and lead wire specifications. Confirm that the primary current rating matches the system load requirements. Ensure the sensing window diameter accommodates the conductor size. Cross-reference the datasheet for insulation voltage ratings and thermal limits before finalizing procurement.

Selection Notes

Select this component when a high-current, non-invasive sensing solution is required for frequencies up to 400 Hz. The 800:5 ratio is appropriate for heavy industrial loads. Consider the physical dimensions of the sensing window relative to the busbar or cable being monitored. Verify compatibility with downstream instrumentation accepting 5A secondary inputs.
