Schneider Electric METSECT5DA050 PowerLogic CT 500/5 A Class 0.5 65 x 32 mm Busbar Current Transformer

The Schneider Electric METSECT5DA050 is a PowerLogic solid-core current transformer tropicalised for busbar mounting, with a 500/5 A current ratio and a 65 x 32 mm busbar opening. It is rated Class 0.5 accuracy (Class 0.5 at 8 VA, Class 1 at 10 VA) with a 30 kA thermal withstand current, built for insulated locking-screw installation directly on the busbar.

Selection Notes

This busbar-mount CT is matched to a 65 x 32 mm bar window, so the opening size — not just the current ratio — determines whether it fits the switchboard's existing busbar cross-section; a higher-current sibling in the same window size shares the identical mounting footprint, which simplifies retrofits. Its 30 kA thermal withstand current tracks the 500 A rating, giving the short-circuit margin needed when the CT sits directly on a high-fault-level busbar rather than a cable. Use the Class 0.5 tap for sub-billing or revenue metering and the Class 1 tap for standard panel indication on the same core.
