This breaker is built for distribution boards, sub-panels, and industrial control enclosures in mechanical engineering and industry. Dual compliance with both IEC 60898-1 (household-type) and IEC 60947-2 (industrial) means the same part number can be specified across the plant floor and the building's power distribution — one line item for procurement. Combined (busbar/terminal) top and bottom connections simplify wireways and busbar routing. IP20 with conductors connected is standard for enclosed panels.","metaTitle":"Siemens SENTRON 5SY4230-7 MCB, 2P C-curve, 10kA","metaDescription":"Siemens SENTRON 5SY4230-7 miniature circuit breaker, 2-pole C-curve, 10kA (EN 60898) / 20kA (IEC 60947-2).
