ACTL-1250-400 OPT C0.6

Current Sense Transformers Overview

The Continental Control Systems ACTL-1250-400 OPT C0.6 is a revenue-grade split-core current transformer designed for precise electrical measurement. It features a rated primary current of 400 A and a turns ratio of 100:1, operating at standard 50/60 Hz frequencies. The device delivers high accuracy with an error limit of ±0.50% and a phase angle error of ±0.25°, complying with IEEE C57.13 Class 0.6 standards. It includes an integral burden resistor producing a standard 0.333 Vac output at full scale, eliminating the need for external shorting blocks.

Current Sense Transformers Feature Summary

• Revenue-grade split-core technology ensuring exceptional linearity and low phase angle error for accurate metering applications.
• Built-in integral burden resistor provides a standard 0.333 Vac output, enhancing safety by removing the requirement for shorting blocks.
• Non-invasive oval window opening accommodates conductors up to 1.25 x 1.77 inches, suitable for parallel conductor installations.

Current Sense Transformers Applications

• Revenue-grade energy metering in commercial and industrial power distribution systems
• Electrical monitoring and protection schemes requiring high accuracy
• Installation on busbars or large cables where non-invasive access is required

Current Sense Transformers Procurement Notes

Verify that the specific order suffix OPT C0.6 corresponds to the Class 0.6 accuracy rating and associated documentation. Confirm the physical dimensions match the installation space, particularly the oval window size for the target conductor configuration. Ensure the system burden requirements align with the internal resistor specifications to maintain accuracy within the stated limits.

Current Sense Transformers Selection Notes

Select this model when a 400 A rated current is required alongside revenue-grade accuracy standards. The split-core design facilitates installation without disconnecting primary conductors. Consider the 100:1 ratio and 0.333 Vac output compatibility with downstream metering or data acquisition equipment. Verify environmental conditions against the device's operational specifications.
