Crompton 243 Switchboard Ammeter – 72x72mm Panel Mount, Quad Scale M.I.

Description

Moving iron (M.I.) switchboard ammeter with 90-degree quadrant scale for direct panel mounting. The moving iron movement is robust and accurate, requires no external power supply, and reads true RMS on AC circuits. 72x72mm face (68x68mm panel cut-out). Each rating includes an overscale range for reading higher currents via CT. For CT-connected applications, fit the matching scale plate (sold separately) to display the primary current directly.

Note: For CT-connected installations, you will need the matching 243 ammeter scale plate to show the correct primary current reading. Scale plates are available for CT ratios from 40A to 3000A.

– 243-026G-1A: 1A, overscale 6A
– 243-026G-5A: 5A, overscale 30A
