Phase and Earth Overcurrent and Undercurrent relays
The ITG relays of the 7000 and 7100 series form a complete range of overcurrent and undercurrent relays, providing instantaneous or definite time protection against phase or earth faults, with either one or two pick-up levels.
The ITG 7--5 and 7--6 series are a range of electronic relays which are notable for their wide current and time setting ranges. The various models provide a complete range of overcurrent relays of definite, inverse, very inverse, extremely inverse, slightly inverse time types and/or earth fault protection relays with high set unit (ITG 7--6) or without high set unit (ITG 7--5).
Their modular draw-out case, type R, may be mounted either as a separate relay, flush or projection mounting, or as an alement in a standard 19" rack cradle.
