Schneider Electric METSECT5GG075 PowerLogic GG Type 750/5 A Class 0.5 85 x 125 mm Current Transformer

The Schneider Electric METSECT5GG075 is a PowerLogic split-core current transformer for standard busbar, with a 750/5 A ratio and a 85 x 125 mm opening. It scales the 750 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 METSECT5GG075 is sized for the 85 x 125 mm window used across the GG 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 45000 A 1-second withstand rating with a 5x safety factor indicates how much fault current it tolerates before the secondary saturates.
