Electric and thermal magnetic tripping device for NS MCCB has passed IEC, CE

 

Application of MCCB                                                                                                                                      

 

SM6 MCCB is suitable for using in the circuit of AC 50/60Hz, please make remarks when ordering, rated insulating voltage 750V, rated working voltage below 690V, and rated current is 16A to 1250A for distributing electric energy, and infrequently OFF/ON under normal condition. The intelligent MCCB, which the rated frame rank current is 800A and below, also can be used for infrequently switching and starting of squirrel cage motor and for protecting motor from over-load, short circuit and under-voltage.

 

Working conditions of MCCB                                                                                                                      


1. Not over altitude 2000m;
2. Ambient temperature is between-25°C and +40°C ; Working in the medium which not any   explosive, not enough dielectric to corrode metal, no gas to damage insulation and electric conduction dust;
3. Working in the place would not be invaded by rain and snow;
3. Pollution degree3;
4. Mounting type.

 

Classification of MCCB                                                                                                                                  

 

1) According to using: distribution circuit protection type, motor production type;
2) According to connection mode: front panel connection, back panel connection, plug-in connection;
3) According to operating way: for direct handle operating, for motor operator operating, for rotary handle operating.
4) According to the number of pole: 3,4 pole.
5) According to the accessory: with accessory setting, and without accessory setting.
