Applications
TG- M-NZS series moulded case circuit breaker is one of new type breakers which my company adopts international advanced design, manufacture technology to develop, The rated insulating voltage is 950V. Sui-table for AC 50Hz(60Hz). Rated working voltage 690V or below, rated working current is 12. 5A 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 mouse cage motor's non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage. The product comply with IEC60947-2 stardand.
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;
According to connection way: Front panel connection, Back panel connection, plug-in connection;
According to operation way: For direct handle operating for exernal rotary handle operating, for motor operating;
