Item #E243-02Q-G-PZ**-C7-SW6, AC Ammeters and Voltmeters with Selector Switch – CROMPTON

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.
