Feeder Protection: NPF910
The NPF910 relay protects three-phase electrical networks against non-directional phase to earth and phase to phase faults. This relay has a built-in recloser. It is modular and customisable with up to four I/O or communication cards.
Do you need Directional Overcurrent and Voltage protection as well? Consider the NPF915.
ANSI functions for NPF910:
50 / 51 / 50N / 51N / 50H / 51H / 68H / 46 / 46R / 46L / 49L / 87N / 50BF / 52BF / 74TC / 79 / 68
This relay is part of the NP900 range, offering multi-function protection and communication using IEC61850, GOOSE and MODBUS protocols (Ethernet and fibre optic communication options available). A full brochure is available on the NP900 range page
