FEATURES AND BENEFITS
The Global Pro-tection system from Littelfuse is the world’s
only fuse system designed for use anywhere, in any equipment, in virtually any country. The Global Protection system
simplifies circuit protection by incorporating North American
electrical requirements into fuse styles found in the rest of
the world. The system’s reduced size, touch-safe design,
and international acceptance make the Global Pro system
the easy circuit protection choice for engineers and equipment designers everywhere.
Global Pro fuses provide quick and positive visual identification of blown fuses by using a pop-up indicator design that
protrudes from the top of the fuse, immediately alerting
maintenance personnel that it needs to be replaced. The
pop-up indicator is designed to activate a microswitch that is
built into every Global Pro system to activate stack-lights or
to integrate into PLC networks and provide equipment operators with a remote method of determining when the fuse
needs to be replaced.
The Global Pro system is designed to save valuable space
in a crowded panel while providing designers with the flexibility of a universally accepted design for easy replacement.
Global Pro fuses are far more compact and have greater
power handling capability than conventional products.
Global Pro fuses are up to 75% smaller than Class RK5
fuses and up to 50% smaller than Class J fuses while providing the time delay characteristics that are necessary for
motor circuit protection.
