DescriptionProduct PhotosProduct DescriptionThe YFM1 series molded
case circuit breaker is one of the new circuit breakers that we
designed and developed by comprehensively adopting internationally
advanced techniques.Its rated insulation voltage is 800V.It is
suitable in the AC 50Hz or 60Hz power distribution networks and
circuits with a rated operating voltage up to 690V and a rated
current up to 800A and is over load,short circuit and
under,shuort circuit and under voltage.The circuit breaker is
classified as Type L (standard type),Typr M(higer make-break type)
and Type H ( high make-break type) by the rated limit
shuort-circuit make-break capacity.This circuit breaker is
characterized by the small size ,high make-break capacity and short
flashover.This circuit breaker complies with IEC60947-2 and
GB14048.2-2008.Product ParametersInstructions for installation and
