Schneider Electric METSECT5GJ300 PowerLogic GJ Type 3000/5 A Class 0.5 85x165mm Current Transformer

The Schneider Electric METSECT5GJ300 is a PowerLogic Type GJ split-core current transformer for busbar mounting, ratio 3000/5 A, Class 0.5 accuracy at 15 VA. Its 85 x 165 mm window clips around a single bar up to 80 x 160 mm (single output) without disconnecting the busbar, feeding a 5 A secondary to a power meter or protection relay on a 3000 A main or feeder circuit.

Selection Notes

The METSECT5GJ300 covers a 3000 A busbar run through its 85 x 165 mm window; lower-current variants in the same GJ frame use the identical window for smaller bars, so the 3000 A rating is the deciding factor when selecting between them. Class 0.5 accuracy makes it suitable for revenue-grade or sub-billing energy metering, not just coarse load indication. Mounting by screws onto the busbar or a DIN rail suits a fixed panel installation rather than a retrofit clamp.

Applications

On a 3000 A busbar, the METSECT5GJ300 is typically paired with a panel meter or protection relay that reads its 5 A secondary, giving load, demand, or earth-fault current visibility on an incoming feeder or a main bus section without a dedicated switchgear-mounted sensor.
