Product Description

Product Description

 

Product Description:

  DPX type Moulded Case Circuit Breaker is suitable for industrial or commercial power and lighting with AC50/60Hz, Rated working voltage up to AC660V/DC250V, rated current up to 630A. Its a kind of economical Breaker with the characters of stable and reliable function, beautiful appearance, small size and long life.
It can be used for conversion of line and infrequent starting motor. It can also be attached to install the Accessories which have protection function for avoiding loss-voltage, under voltage. The product can Install connection line with front board and back board, it also can equip hand-operating apparatus or Motor-operating apparatus to control in a remote distance.

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;
