Panel metering switches fall generally into two groups Ammeter Voltmeter switches. Ammeter switches can be directly connected, but more generally are fed from current transformers (C/T s). When C/T fed, the switch must have make-before-break contacts when switching between phases, as an open circuit could generate dangerously high voltages. This page shows a selection of standard Ammeter Voltmeter formats, but if your requirement is somewhat different, then please give our technical sales a call , and they will be pleased to discuss your individual requirements.
