Schneider Electric METSECT5HD050 PowerLogic HD Type 500/5 A Class 0.5 27.9mm Current Transformer

The Schneider Electric METSECT5HD050 is a PowerLogic Type HD split-core current transformer for cable mounting, ratio 500/5 A, Class 0.5 accuracy at 1 VA. It clips around a cable up to 27.9 mm diameter without opening the circuit, supplying a standard 5 A secondary to a power meter or protection relay on a 500 A feeder.

Selection Notes

The METSECT5HD050 clamps onto a cable up to 27.9 mm diameter for a 500 A feeder without breaking the conductor, which is the main reason to pick a HD split-core type over a solid-core busbar transformer. Class 0.5 accuracy makes it suitable for revenue-grade or sub-billing energy metering, not just coarse load indication. Choose the next current rating in the HD series if the measured feeder load exceeds 500 A, since the window size stays the same across the family.

Applications

The clip-on HD body lets a panel builder add the METSECT5HD050 to an existing 500 A cable run during a metering or protection upgrade, without disconnecting the conductor or shutting down the circuit to fit the transformer.
