Specifications

Accuracy

The accuracy specifications apply over the full operating temperature range (-30°C to 55°C) unless otherwise noted. Standard models are calibrated for optimum accuracy at 60 Hz. For use with 50 Hz services, we recommend ordering with Option 50Hz.

The following accuracy specifications apply to the standard model (no options) or for Option C0.6; the specifications may vary for other options, so see the details on individual options for specifications.

Standard Accuracy

Accuracy: ±0.75% from 1% to 120% of rated primary current
Phase angle: ±0.50 degrees (30 minutes) from 1% to 120% of rated current
IEEE C57.13 accuracy: class 1.2 from 1% to 120% of rated current
IEC 60044-1 accuracy: class 1.0 from 1% to 120% of rated current
Note: The ACT-0750-250 specifications apply at 120% of rated current only at temperatures of 40°C and below.

Option C0.6 Accuracy

With Option C0.6, the Accu-CT is calibrated and verified to meet IEEE/ANSI C57.13 class 0.6 accuracy and IEC 60044-1 class 0.5 S accuracy and each CT is shipped with a certificate of calibration.

Accuracy: ±0.50% from 1% to 120% of rated primary current
Phase angle: ±0.25 degrees (15 minutes) from 1% to 120% of rated current
IEEE C57.13 accuracy: class 0.6 from 1% to 120% of rated current
IEC 60044-1 accuracy: class 0.5 and 0.5 S from 1% to 120% of rated current
Available Models: Option C0.6 is only available for ACT-0750-030, ACT-0750-050, ACT-0750-070, ACT-0750-100, ACT-0750-150, ACT-0750-200, and ACT-0750-250
Note: The ACT-0750-250 Opt C0.6 specifications apply at 120% of rated current only at temperatures of 40°C and below.

Options

Opt C0.6

With Option C0.6, the Accu-CT meets IEEE/ANSI C57.13 class 0.6 accuracy and IEC 60044-1 class 0.5 and class 0.5 S accuracy from -30°C to 55°C and from 1% to 120% of rated primary current.

Note: the ACT-0750-250 Opt C0.6 accuracy is only specified to 100% of full-scale primary current (other models are specified to 120%).
Accuracy improves to ±0.5% from 1% to 120% of rated primary current from -30°C to 55°C.
Phase angle improves to ±0.5 degrees from 1% to 120% of rated primary current from -30°C to 55°C.
Includes a certificate of calibration
- Order option C0.6,N if you need the C0.6 accuracy, but do not need a certificate of calibration.
Not available for 5, 15, and 20 amp Accu-CT models.

Opt 50Hz

Standard models are calibrated for optimum accuracy at 60 Hz. Option 50Hz calibrates for best accuracy at 50 Hz. Option 50Hz models have the same accuracy specifications as standard models and are also available in combination with Option C0.6 for higher accuracy.

Opt FT

The Accu-CT can be ordered with custom lead lengths. For example, Opt FT=50 for 50 foot leads. We also sell extra lead wire to allow for field extension of the leads. Option FT does not affect the accuracy specifications.

Advanced Options

The Accu-CT advanced options are generally not useful when ordering the Accu-CT for use with a WattNode^® meter, but may be useful for other applications.
