The rotor indicator is a mechanical short-circuit indicator. It is designed to detect short-circuit currents in medium voltage distribution networks.

The indicator is tripped by a magnetic field strength “H” which is induced by trip values I>>. The pivoted rotor with reset pin uses a two-colour indication to inform the user of the state of the Rotor Indicator. “Black” means that the indicator has not been tripped whereas “red” indicates that the indicator has been tripped.
