The Instrument Transformer 19SHT-101 is a single-phase indoor current transformer belonging to the Model 19 series. It features a window-type design with a specified current ratio of 100:5 A. The unit operates at a frequency of 60 Hz and is rated for metering class applications, ensuring high accuracy for power monitoring. This component is designed for integration into electrical systems requiring precise current measurement.
Verify the specific current ratio and physical dimensions against the original equipment specifications before procurement. Confirm that the indoor rating aligns with the installation environment requirements. Ensure compatibility with existing busbar or cable sizes to guarantee proper fit within the transformer window.
Select this model based on the required 100:5 A ratio and single-phase configuration. Consider the indoor application constraints and the need for metering-grade accuracy. Evaluate the physical space available for the window diameter to ensure mechanical compatibility with the target conductor size.
The 19SHT-101 is part of the broader Model 19 instrument transformer family, which includes various ratios such as 200:5 A and higher values like 1800:5 A in related models. These transformers are generally ANSI Metering Class devices intended for applications demanding high accuracy and minimal phase angle error in power monitoring scenarios.
