Panel instruments are indicating devices on electrical panels that monitor line parameters viz. voltage, current, power, frequency and the position of the circuit breakers and isolators. These instruments can be analog or digital and comply with DIN standards. These instruments come in industry standard enclosures, 96X96mm, 96X48mm, to cater to different size of panels and to save on the space.

Position indicators are used to indicate the position of circuit breakers and isolators, position of valves on instrument panels or in mimic panels.
