Product Description

 

Product Description:

  DC/AC 80A-1600A 3 pole 4 pole Moulded Case Circuit Breaker CZNS CZNSX MCCB ,(NSX) 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;
