Its 10 kA breaking capacity at 440 V DC (per IEC 60947-2) means it can safely interrupt a fault current up to that level without welding contacts or cascading failure upstream — critical for DC bus protection in drives, solar combiner boxes, or battery-backed control panels. Snaps onto 35 mm DIN rail, occupies 2 modular width units (36 mm). Installation depth 70 mm. Rated IP20 with connected conductors. The sealable design allows panel builders to lock the toggle position with a lead seal after commissioning.","metaTitle":"Siemens 5SY5204-6CC SENTRON MCB, 2P B-Curve 4A, 440VDC 10kA","metaDescription":"Siemens SENTRON 5SY5204-6CC miniature circuit breaker, 2-pole, B-curve, 4 A, 440 V DC, 10 kA breaking capacity per IEC 60947-2.
