RCT1513005A

Current Sense Transformers Overview

The Omega RCT1513005A is a toroidal AC current transformer designed for low-voltage applications, specifically serving as a sensor interface for ammeters and wattmeters. It features a primary-to-secondary current ratio of 300:5 A, enabling the measurement of high currents by stepping them down to a standardized 5 A output suitable for instrumentation. The unit operates with an accuracy class of Class 1 and has a power rating of 40 VA. Its core design includes a circular window diameter of 35 mm, allowing for the passage of busbars or cables without interrupting the circuit. This component is constructed to provide reliable signal conversion in electrical monitoring systems.

Current Sense Transformers Feature Summary

Current Sense Transformers Procurement Notes

Verify that the required primary current matches the 300 A specification and that the connected instrument accepts a 5 A secondary input. Confirm the application voltage is within the low-voltage range intended for this series. Ensure the conductor size fits within the 35 mm window aperture. Check for Class 1 accuracy requirements against your specific metering standards. Validate the 40 VA burden capacity compatibility with your downstream device impedance.

Current Sense Transformers Selection Notes

Select this model when a 300:5 transformation ratio is required for accurate low-voltage current measurement. Consider the 35 mm window size to ensure it accommodates the specific cable or busbar dimensions of the installation. Evaluate the 40 VA power rating to guarantee the connected meter does not exceed the transformer's burden limit. Choose this toroidal type for applications requiring simple, through-hole installation without breaking the primary circuit.
