125 series DC miniature circuit breakers are suitable for rated currents up to 125A and rated DC voltages 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 electric power, transportation, mining, and others requiring reliable DC circuit protection. Compliant with IEC60947-2 standards, these miniature circuit breakers can be connected with a maximum 100AgL fuse (>10kA). They feature a characteristic curve with selection level 3, ensuring accurate protection coordination. The operating temperature range is -10C to +40C, and the protection level is closed-type design. The electrical life is not less than 8,000 operations, with a corresponding mechanical life. Available rated currents: 80A, 100A, 125A. Rated breaking capacity meets applicable standards. Package includes: 1 x Circuit Breaker
