Did you know that…
A variety of wire or foil fusible elements
were in use to protect telegraph cables
and lighting installations as early as
1864. A fuse was patented by Thomas
Edison in 1890 as part of his electric
distribution system.

FUSES = FUSIBLES
DIRECT CURRENT FUSES ES UN DISPOSITIVO CUYA FUNCION PRINCIPAL ES PROTEGER EL CIRCUITO
CUANDO VA ACOMPAÑADO DE UNA SEÑAL DE CORRIENTE CONTINUA.
1. DC fuses DI SI FIUSES CUANDO LA CORRIENTE EN EL CIRCUITO EXCEDE UN CIERTO VALOR, LOS
FUSIBLES SE ROMPEN POR EL CALOR GENERADO POR LA INTENSIDAD, TODO
EL CIURCUITO SE DESCONECTA.
A device whose main function is to protect the
circuit when it is accompanied by a continuous
increase in current. When the current in the
circuit exceeds a certain value, the fuse will be
broken by the heat generated by it, thus the
entire circuit will be disconnected. The internal
structure of the DC fuse is made of metal with

MAXIMO.
2. AC fuses EI SI FIUSES - DEBIDO A ESTO, LAS POSIBILIDADES DE ARCO ENTRE LOS CABLES
DERRETIDOS ES ELIMINADA.
Air Conditioning (AC) fuses are a
little bit small in size as compared to
DC fuses as they oscillate at about
50-60 times every second from
minimum to maximum. Because of
this, the chances of arc between the
melted wires is eliminated. Hence,
they can be parked in small sizes.

fuse cap where the cartridge is inside
the fuse cap. The circuit is completed
when the tip of the cartridge makes
contacts through the fuse link conductor. EL CIURCUITO ESTARA COMPLETO CUANDO LA PUTNA DEL

The fuse wire carries a short circuit
current in a set period. If the fault
occurs in the circuit then it blows off. It
is made with glass otherwise some
other kind of chemical compound.
At both sides of the fuse, the ceramic
enclosure is made with a metal cap
which is welded with fusible silver wire.

High Voltage (HV) fuses are used in
power systems to protect the power
transformer, distribution transformers
and instrument transformer where circuit
breakers may not be able to protect the
system. They are rated for more than
1500V and up to 13kV and are generally
made of copper, silver or tin. ESTAÑO

Also known as spade or plug-in fuses
come in plastic body and two metal caps
to fit in the socket. Mostly, they are used in
automobiles for wiring and short circuit
protection. Fuse limiters, glass tube (also
known as Bosch fuse) are widely used in
automotive industries. The rating of
automobile fuses are low as 12V to 42V.

The kit-kat or rewireable fuse is mostly used in
industries and home electrical wiring for small
current applications in Low Voltage (LV) systems.
Contains 2 basic parts: The inner fuse element as
fuse carrier made of tinned copper, lead or
aluminum and the base made of porcelain having
the IN and OUT terminals which is used to be in
series with the circuit to protect. Its main advantage

Also known as Thermal Cutouts (TCO) or
Thermal Links they are a one time used only
fuse. They are made of temperature sensitive
alloy. The fuse element holds a mechanical
spring contact which is normally closed. When
high currents due to over current and short
circuit flow through the elements of the fuse,
the fuse elements melts down which lead to
release the spring mechanism and prevent fire.

Polymeric positive temperature coefficient device
(PPTC), poly-switch, poly-fuse or resettable fuse
is a passive electronic component used to
protect against short current faults in electronic
circuits. They open the circuit when an over
current event occurs and after some specific
time they connect the circuit again. Its
application is to overcome where manually
replacing fuses is difficult or almost impossible.

Conclusions
A fuse is an electric / electronic or mechanical device, used to protect
circuits from over current, overload and ensure the protection of the circuit.
Electric fuse was invented by Thomas Alva Edison in 1890. Fuse consists of
a low resistance metallic wire enclosed in a non combustible material. It is
used to connect and install in series with a circuit and device which needs to
be protected from short circuit and over current. The working principle is
based on the “Heating effect of Current”. Whenever a short circuit, over
current or mismatched load connection occurs, the thin wire inside the fuse
melts because of the heat generated by the heavy current flowing through it.
