• a novel solution for circuit protection
• from OVER-CURRENT
• The Polymeric PTC device replaces one-time use
  fuses.
• Instead of the traditional fuse wire,
• the PPTC fuse uses a patented polymer based
  technology
• which allows it to be reset thousands of times .

Polymeric Resettable Fuse Device

• When connected in series to a circuit, the PPTC
  resettable device remains at extremely low
  resistance and allows the electrical current to
  flow through it without any restriction.
• When over current occurs, the devices reacts to
  the heat generated by excess current. On reaching
  the specified trip current level, it changes
  from low resistance to a very high resistance
  thereby limiting the fault current to a very
  small value (nearly to open state).
• Once normal current is restored, the device
  resets back to its normal state of low
• resistance and allows the current to flow through
  once again.

• HOW IT WORKS
• .

FUZETEC resettable fuses are made of patented
novel PPTC material in thin chip form where
conductive particles are dispersed in a polymer
that has a crystalline structure. At normal
operating conditions there are numerous chains
forming conductive paths throughout the PPTC
material. Under fault conditions (tripped
state), excessive current flows through the PPTC
device and the PPTC material heats up. This makes
the polymer matrixs morphology change from
crystalline to amorphous. Under these conditions
the conductive particles move apart from each
other, most of them no longer conduct current and
the resistance of the device increases sharply.
Upon fault current being removed, the resettable
fuse is reset and allows the current through the
circuit again.
