MERSEN

NH fuse-links NH3, aM

500 V AC, 690 V AC

Mersen/Ferraz Shawmut aM type NH fuses are suitable for protecting motor circuits. Partial range breaking capacity. Suitable for short-circuit protection only, interrupts current from 6,3 x ln up to maximum breaking capacity. They must be associated with other switchgear for protection against overloads. These fuse-links can have a rated current equal to the motor's nominal current.
