Residual Current Circuit Breakers
Open the catalog to page 1
Residual Current Circuit Breakers Type F - NFIF Features ISKRA NFIF are type F residual current circuit breakers (RCCB) for which tripping is ensured as for type A and in addition for residual currents with mixed frequencies that can result from single-phase electrical loads with frequency inverters. Intended for protection when using washing machines, vacuum cleaners, dishwashers, heating pumps, lighting systems … . Capable of detecting mixed frequencies up to 1 kHz The tripping characteristic of type F is not influenced by smooth d.c. residual currents up to 10 mA. Functions of detection, evaluation...
