NPIH(D)800R - Digital Protection of homopolar current with or without directional criterion
Current Protection
NPIH(D)800R ensures the detection of homopolar currents of medium and high voltage electricity networks. This digital and multifunction and directional (D) relay monitors faults between phase and earth, and also the proper functioning of the circuit breaker and its triggering circuit.
These functions associated with an R type modular unit, thus allow the NPIH(D)800R to be used for quick replacement, by equivalence of function, of the relays of the CEE relays of the 700 and 7000 series (mechanical interchangeability).
Product family:
Renovation of 700 & 7000 Series Relays
ANSI code :
50N - Instantaneous earth fault overcurrent
51N - Earth fault overcurrent
67N - Earth directional overcurrent
86 - Latching of the output contacts
74TC - Trip circuit supervision of the breaker
50NBF - Breaker failure with earth fault overcurrent
