Product Description
Features
- Software based design
- Programmable time current characteristics
- Choice of four IDMT curves
- Draw out case
- Wide range auxiliary supply
- Low burden
DESIGN AND OPERATION
The relay measures the line current from each of the phases
and if exceeds the set operating current, then relay extends a
trip signal after the operating time. The relays operating time is
determined by selecting one of the four inverse time current
characteristics. The relay has facility to active / inhibit the high
set protection feature. The relay output contacts are self reset
type. Relay operation without any fault current is determinated
by trip test facility.
