FUSES
The system and its supply/interconnecting wiring must be protected by fuses, preferably High Rupture
Current (HRC) motor rated types (EN60269) or miniature circuit breakers (EN60898) or local codes having
similar time lag characteristics, that allow starting of the compressor yet still afford close overcurrent
protection under running conditions. The ratings below are for HRC motor rated fuses.
