Features:
•
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
