Schneider Electric METSECT5GJ250 PowerLogic GJ Type 2500/5 A Class 0.5 85 x 165 mm Current Transformer

The Schneider Electric METSECT5GJ250 is a PowerLogic split-core current transformer for standard busbar, with a 2500/5 A ratio and a 85 x 165 mm opening. It scales the 2500 A primary current down to a 5 A secondary signal at Class 0.5 accuracy, and the split core opens to mount around an existing busbar without disconnecting the primary conductor.

Selection Notes

The METSECT5GJ250 is sized for the 85 x 165 mm window used across the GJ type body; within that frame, choose the ratio that matches the installed primary current rather than the busbar size, since several ratios share the same window. Its split core lets it be fitted around a live busbar without breaking the circuit, and the 60000 A 1-second withstand rating with a higher 10x safety factor indicates how much fault current it tolerates before the secondary saturates.
