INTRODUCTION AND APPLICATIONS
CDSM2 series moulded case circuit break er is one o f new typ e break ers whi ch this co mpany
adopts international advanced design,manufacture technology to develop,The rated insulating
volta ge is 9 50V.Suit
able f or AC 50H z(60H z).ra ted working voltage 690v or below,rated working
current is 12.5 to 630A of circuit.and use in distrbuting electric energy.Non-frequ ent makin g
and breaking in the normal conditions and protecting when circuit and installation are overload,
short citcuit and lacking voltage.Rated shell-rack and the breaker which current is under 400A,
take protect effect when mousecage motor s non-frequent start.,brea
-
king off working and
protecting overload,short circuct and lacking voltage.
CLASSIFICATION OF MCCB
Installation type of MCCB:MCCB are suiable for vertical or harizontal installation.
According to use of MCCB:Distribution circuit protection type,motor protection type;
Accor ding t o conn ectio n way: Front panel connection,Back panel connection,plug-in connection;
According to operation way:for direct handle operating,for external rotary handle operating,for
motor operation;
Accrd ing to ov erloa d relea se type :magnetic release(only instantaneous)the modynamic magnetic
type(dual)
Accrding to number of poles:Two poles,Three ploes,Four poles;
The neutral ploe(N pole)of four ploe MCCB has four types;
TypeA:No overload release on N pole,which is making at the time;not closing and opening
with the other three poles.
TypeB:No overload release on N pole.which closing and opening with the other three poles.
TypeC:with overload release on N pole.which closing and opening with the other three poles.
TypeD:with overload release on N pole.which making all time:not closing and opening with the
other three poles.
