Retrofitting solutions providing protection integral to the mining industry

NHP is proud to bring to market the Protek NEF series of 1000V AC electronic motor protection relays, ideally suited for mining related applications.

This product has been specifically designed as a retrofit solution to supersede the now obsolete CEF1. The compact footprint of the NHP Protek NEF ensures a quick and easy replacement with minimal installation time. Change-over from CEF1 to NHP Protek NEF is simplified thanks to the use of an optional adapter plate.

To optimise inventory, the NHP Protek NEF is available in two units, each one is complete with its associated integral current converter unit.

The first unit covers 0.825 up to 40A, the second unit covers the current range 33 up to 160A.

Rated to 1000V AC and complete with remote reset facility as standard, the NEF series offers rapid phase failure protection, asymmetry detection and a PTC thermistor input. As your complete motor protection solution, the NEF series also offers DIP switch setup and LED indication.

For quality motor protection in 1000V AC applications, the NHP Protek NEF is the ideal choice.
