Crompton 243 Ammeter Scale Plate – 72x72mm, CT Ratio

Description

Replacement ammeter scale plate for the Crompton Model 243 switchboard ammeter (72x72mm). These scale plates are used when the ammeter is connected via a current transformer (CT) — the plate displays the primary current directly so the operator reads the actual circuit current without needing to calculate the CT ratio. Quad scale M.I. format, x/5A CT ratio.

Note: Select the scale plate that matches your CT ratio. The ammeter must be a Crompton 243 with x/5A CT connection. Scale plates simply clip into the ammeter face and can be swapped without removing the instrument from the panel.

– 243-SCALE-40A: 40A CT Ratio
