Product Description

Instrument Switch including Ammeter Switch and Voltmeter Switch.

The Ammeter Switch is connected to Ammeters, the purpose being monitoring of current in all the respective phases current R.Y.B.

The Voltmeter Switch is connected to the voltmeter, to measure voltages between phases (Line voltages RY. YB. BR) and Between Phase to Neutral (Phase Voltage RN. YN. BN) with a single voltmeter. Here also the purpose is to save cost of two more voltmeters.

Crossing Competetior: Kraus & Naimer 's Rotary Cam Switch
