125 series DC miniature circuit breakers are suitable for applications with rated current up to 125A and rated DC voltage of 220V and 600V. These breakers are primarily used for overload and short circuit protection in DC power distribution systems and electronic equipment. They can be widely applied in industries such as power, transportation, mining, and others requiring reliable DC circuit protection. Compliant with IEC60947-2 standards, these miniature circuit breakers can be connected to a maximum 100AgL fuse (>10kA). Features include characteristic curve selection level 3, operating temperature range from -10°C to +40°C, and a closed protection rating. The electrical life is not less than 8,000 operations, with corresponding mechanical durability. Available rated currents: 80A, 100A, 125A. Rated breaking capacity per specifications. Package includes: 1 x circuit breaker
