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.
