What is Fuse?
                     WHAT IS 
FUSE?
• A fuse is like a safety guard for electrical 
circuits.
TYPES OF FUSE 
Cartridge Fuse
HRC (High Rupturing Capacity) Fuse
DIN Fuse
Semiconductor Fuse
Resettable Fuse 
CARTRIDGE FUSE
• This is a type of fuse where a 
fuse wire is enclosed in a 
cylindrical cartridge, usually 
made of glass or ceramic. 
These fuses are commonly 
used for protecting electrical 
circuits in industrial 
machinery.
HRC (HIGH RUPTURING 
CAPACITY) FUSE
• HRC fuses are designed to 
withstand high fault currents 
and provide reliable protection 
against short circuits. They 
have a high breaking capacity 
and are often used in heavy-
duty industrial applications.
DIN FUSE
• DIN fuses are standardized 
fuses designed to fit into DIN 
rail-mounted fuse holders 
commonly used in industrial 
control panels and automation 
systems.
SEMICONDUCTOR FUSE
• These fuses are specifically 
designed to protect 
semiconductor devices such 
as diodes, thyristors, and 
transistors from overcurrent 
conditions. They have precise 
characteristics to ensure the 
safe operation of sensitive 
electronic components.
RESETTABLE FUSE (PTC 
FUSE)
• Unlike traditional fuses, resettable 
fuses are designed to 
automatically reset after a fault 
condition is cleared. They are 
often used in industrial 
automation for applications where 
frequent overcurrent protection is 
required without the need for 
manual replacement.
