630A Molded Case Circuit Breaker from China MCCB

 

 

 

HYCM8 series Moulded Case Circuit Breaker is one of new type breaker which is SIQI adopts international advanced design, manufacture technology to develop it. The rated insulating voltage is 750V, suitable for AC 50Hz(60Hz), rated working voltage 690V or below, rated working current is 12.5A to 1250A of circuit and use in distributing electric energy. Nonfrequent making and breaking in the normal conditions and protecting when circuit and installation are overload, short circuit and under voltage. Rated shell-rack and the breaker which current is under 400A, take protect effect when mousecage motor is nonfrequent start, breaking off working and protecting overload, short circuit and under voltage.

 

 2.Innovation structure:

More compact and aesthetically

Intergration can be installed more easier

Easier to increase or decrease of function

 

3 .Model description: 

 

Note: No code for distribution breakes; M represent motor protection circuit breakers. No code for dircet handle operation; presents electrical operation, and presents ratray-operated-handles.

Rated breaking capacity grade of MCCB: D-Economical type; N-Standard type; H-high breaking capacity type.

 

 4 .Classification of MCCB:

 

Installation type of MCCB: MCCB are suitable for vertical or horizontal installation.

According to use of MCCB: distribution circuit protection type, motor protection type;

According to connection way : front panel connection, real panel connection, plug-in connection;

According to operation way: for direct handle operation, for external rotary handle operating, for motor operating;

According to overload release type: magnetic release (only instantaneous), the modynamic magnetic type (dual), electronic release;

According to number of poles: 2 pole, 3 pole, 4 pole.

 

The meutral pole( N pole) of 4 pole MCCB has for types:

Type A: no overload release on N poles, which is making at the time; not closing and opening with the other three pole.

Type B: no overload release on N poles, which closing and opening with the other three pole.

Type C: with overload release on N poles, which closing and opening with the other three pole.

Type D: with overload release on N poles, which is making all time; not closing and opening with the other three pole.

Type L :highest breaking capacity type.
