Schneider Electric METSECT5GA040 PowerLogic GA Type 400/5 A Class 0.5 23 x 33 mm Current Transformer

The Schneider Electric METSECT5GA040 is a PowerLogic split-core current transformer for standard busbar, with a 400/5 A ratio and a 23 x 33 mm opening. It scales the 400 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 METSECT5GA040 is sized for the 23 x 33 mm window used across the GA 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 24000 A 1-second withstand rating with a 5x safety factor indicates how much fault current it tolerates before the secondary saturates.
