Technical Data
825 Plus
Refer to Publication 825-UM004_-EN-P.
Conversion Kit Interface Panel
Description Specification
Ground Fault Interposing Current Transformer
Primary 1A
Secondary 5A
Operating Frequency 50/60 Hz
Class 600 V
Accuracy Less than 2% ratio error at 5 VA burden
Primary Impedance 2.5 ohms
Approvals CSA certified and UL listed
Important: This current transformer is used to step down an existing 50:5 ground fault current transformer.
The secondary of this current transformer is connected to the secondary of the existing ground
fault current transformer. This results in an equivalent 50:1 ground fault current transformer.
This is done to prevent possible damaging current levels for the 825 Plus.
