A range of high performance, 32-bit ARM based Inverse Definite Minimum Time (IDMT), Inverse Definite Time (IDT) and Definite Time (DT) Relays for monitoring and protecting network feeders against overcurrent and/or earth fault conditions.

Four programmable models are available and include True R.M.S. measurement techniques, 6 selectable IDMT characteristic curves, adjustable DT, pre-defined and selectable CT ratios, Low-set and High-set tripping thresholds and with information being displayed on a clear backlit Liquid Crystal Display. These products have been designed using Ecosmart technology which ensures the power consumption is kept to a minimum whilst meeting all applicable energy efficient requirements.

In addition to the above, five new models which sit beneath the fully programmable versions offer fixed tripping characteristics (IDMT, IDT or DT) along with user adjustable Low-set and High-set tripping thresholds
