Advanced Motor Protection: NPM915
The NPM915 relay protects large motors, including those with two operational speeds, soft starters or star/delta starters. This relay can be adapted to accept up to 16 RTD temperature element inputs.  The NPM915 measures voltage, frequency, current and power and can be programmed to activate alarms or trips based on virtually any combination of these measurements.  It is modular and customisable with up to three I/O or communication cards.

ANSI functions for NPM915: 
50 / 51 / 50N / 51N (S)/ 50H / 51H / 68H / 46 / 46R / 46L / 49M / 87N / 48 / 14 / 86 / 66 / 37 / 55 / 51LR / 59 / 27 / 59P / 27P / 47 / 59N / 81O / 81U / 81R / 32 / 32R / 50BF / 52BF / 60 / 74TC

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
