The 10 kA breaking capacity at 440 V DC (per IEC 60947-2) means this breaker can safely interrupt a DC fault current up to 10 kA without welding contacts or failing to clear — critical for DC bus or battery circuits where arc extinction is harder than in AC. The 2-pole configuration switches both lines in a DC circuit, providing full isolation. Terminals accept solid or stranded conductors from 0.75 to 35 mm², with a tightening torque of 2.5 to 3.5 N·m. The 36 mm width occupies 2 modular units on DIN rail.
