Application Scope
KFM2 KFM2 Series molded case circuit breaker here in after inafter
refered to as simply" breakers" is designed for circuit of 50Hz
50Hz 690V
a.c., rated operational voltage 690V(or below), rated
800A operational current up to 800A. Generally it is used for power
630A distribution. The breaker with rated current of 630A(or below)
can also serve as protection of motor. Normally, KFM2 breaker
is suit for switching-over or motor starting in case of operating
not so frequently.
Distribution breakers are used for power distributing in net and
protect the net and its installation from overload, short-circuit
and under-voltage.
Motor protection breakers are used in 380V (400V) net for
motor starting, switching in its running and protect from
overload and short-circuit.
KFM2 breakers are available in four model according to its
(Icu) rated ultimate short-circuit breaking capacity (Icu): the C model
(Economic breaking capacity 35kA), the S model (Standard
C ( ) S ( ) M ( )
breaking capacity 50kA), the M model (Medium breaking
H ( ) capacity 65kA),and the H model (High breaking capacity 80kA).
