Product Description
NS MCCB (Merlin Gerin Model MCCB)
NS series moulded case circuit breaker is one of new type breakers which this company adopts international advanced design, manufacture technology to develop, The rated insulating voltage is 950V, Suitable for AC 50Hz(60Hz), rated working voltage 690V or below, rated working current is 12.5 to 630A of circuit. And use in distributing electric energy. Non-frequent making and breaking in the normal conditions and protecting when circuit and installation are overload, short circuit and lacking voltage. Rated shell-rack and the breaker which current is under 400A. Take protect effect when mousecage motor's non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage. The product confirms to GB14048.2, IEC60947-2 standards.
Classification of MCCB
1, Installation type of MCCB: MCCB are suiable for vertical or harizontal installation.
2, According to use of MCCB: Distribution circuit protection type, motor protection type;
3, According to connection way: Front panel connection, back panel connection plug-in connection;
4, According to operation way: For direct handle operation for external rotary handle operating, formotor operating;
5, According to overload release type: Magnetic release (only instantaneous) the modynamicmagnetic type (dual), electronical release;
6, According to number of poles: Two poles, there poles, four poles.
7, The neutral poles (N poles) of four poles MCCB has for types:
8, Type A: No overload release on N pole, which is making at the time; Not closing and openingwith the other three poles.
9, Type B: No overload release on N pole, which closing and opening with the other three poles.
10, Type C: With overload release on N pole, which closing and opening with the other three poles.
11, Type D: With overload release on N pole, which making all time; Not closing and opening withthe other three poles.
