General Information:
• These fuses avoid needless openings from starting currents or
surges.
• A fuse link which operates only on very high overloads or
short-circuits.
• Thermal cutout functions on low overloads – the thermal
cutout cannot operate quickly at any load, hence long timelag is obtained on high overloads of short duration.
• This long time-lag also makes it unnecessary to use extra
large size or over-size fuses.
Note: 10-60 amp fuses use brass terminals and ferrules.
70-400 amp fuses use copper terminals and ferrules.
