AC Ammeters and Voltmeters with Selector Switch – CROMPTON

Description click to view larger image These Crompton Instruments DIN sized, moving iron AC ammeters and voltmeters include an input selector switch. The 96mm and 72mm meters offer Class 1.5 true RMS measurement of three-phase AC voltage or current on 3P3W and 3P4W circuits. The integral selector switch eliminates the need for a separate selector switch, saving valuable panel space and providing installation benefits. Both ammeters and voltmeters feature a slide-in dial, scaled for VT or CT values to suit application primary values. These robust moving iron meters incorporate a clapper type repulsion design which utilises a pivot, hairspring and jewel movement. The bottom jewel is oil filled to provide damping while the top is sprung for resilience. Voltmeters are manufactured with internal voltage dropper resistors.
