China DC Miniature Circuit Breaker Manufacturers, Suppliers, Factory

DC miniature circuit breaker is one division of DC circuit breakers.Hereinafter we refer to MCBs,which protect cables against damage due to overload and short circuits.But it will also give protection against earth faults provided that the earth fault loop impedance is low enough. And we have polarized 63A and 125A miniature circuit breakers two types 1P-4P available.

A.Polarized 63A miniature circuit breaker is one branch of DC miniature circuit breakers.They are widely used in solar PV system and communication industry. Characterized by frequency of 50 Hz,rate voltage of DC 250V-1000V and rated current is from 6A-63A,this miniature circuit breakers offer short-circuit and overload protection.Also they are available in 1P-4P.

B.Polarized 125A miniature circuit breaker is the other branch of DC miniature circuit breakers.They are applicable in solar PV system and communication industry. They are characterized by frequency of 50 Hz,rate voltage of DC 250V-1000V and rated current is from 80A-125A.And they have brilliant performance in short-circuit and overload protection. 1P-4P is available and ready to buy.
