Schneider Electric METSECT5MA015 PowerLogic MA Type 150/5 A Class 0.5 27mm Current Transformer

The Schneider Electric METSECT5MA015 is a PowerLogic Type MA tropicalised current transformer for DIN-rail, mounting-plate, or busbar installation, ratio 150/5 A, dual Class Class 0.5 at 3 VA | Class 1 at 5 VA accuracy. It accepts a cable up to 27 mm or a bar through its 32.5 x 10.5 mm or 25.5 x 15.5 mm (double output) opening, supplying a 5 A secondary for metering or protection on a 150 A circuit.

Selection Notes

The METSECT5MA015 covers a 150 A primary through either its 27 mm cable opening or its 32.5 x 10.5 mm or 25.5 x 15.5 mm (double output), so the same part serves both busbar and cable feeders in a panel — pick the next size up in the MA/MB family only if the actual conductor exceeds this rating. Class 0.5 accuracy makes it suitable for revenue-grade or sub-billing energy metering, not just coarse load indication. The insulated locking screw mount works on a DIN rail, a mounting plate, or directly on the busbar.

Applications

Because the METSECT5MA015 mounts on a DIN rail, a mounting plate, or the busbar itself, it fits panel builders retrofitting metering onto an existing 150 A circuit as readily as it does a new switchboard design, feeding the same 5 A secondary to a meter or relay either way.
