IntroductionThe DAM1 series circuit breakers are intended for
conducting current in normal mode and switching it off at short
circuits, overload, inadmissible bucking as well as operational
actuation and tripping of electric circuit parts. They are designed
for use in electric units having the operative voltage limited to
400V per rated current from 12,5 to 1600A. They correspond to
the requirements of EN 60947-1, EN 60947-2 Thermal-Magnetic
Circuit Breakers:Thermal protection function:(For protection under
over load conditions) Bimetal, which provides
thermal protection, consists of combination of two metals
with different extension coefficients under heat. When bimetal
is heated, it bends towards the metal with
less extension. In this way, a notch that assists opening
of the breaker mechanism is released to disable the breaker.
Bending speed of bimetal is in direct proportion with
size of the current passing through the breaker. Because,
increase of current means increase of heat. In this way,
over current protection function of the breaker is
fulfilled by bimetal at load currents higher than the rated
current Magnetic protection function (For protection
under short circuit conditions) Another function of the
breaker is to protect the connected circuit against
short circuits. Short circuit may occur as a result of
contact of phases with each other or contact of phase-ground.
Since a very high current shall pass through the
cables in case of short circuit, system energy should be
broken in a shorter time due to thermal protection.
Breaker should perform instant opening to protect load it
is connected to. The part fulfilling this function is a
mechanical opening mechanism that operates
with magnetization caused by the magnetic area formed by
the short circuit current. Thermal-Magnetic fixed type
