BDM3 Moulded Case Circuit Breaker ( MCCB ) is one of breaker which adopts international advanced design, manufacture technology

BDM3 Moulded Case Circuit Breaker ( MCCB )

Application
BDM3 series moulded case circuit breaker , it’s applicable circuit of AC 50Hz(or 60Hz),rated
insulation voltage 690V(AM3-125 500V),rated operating voltage AC 690V or below ,rated
operating current 12.5-1600A, for distribute energy of electric and infrequent making and
breaking circuit in normal condition. The circuit-breakers are provided with the function of the
protection against overload and short circuit and under-voltage. The circuit breakers comply
with standard of IEC60947-2.The circuit-breakers are double insulating (Inm=250A or above),
the control circuit of the accessories is set apart with the main circuit , and doesn’t need to
open the cover of the circuit-breaker when install the accessories.
