At 1 A, that means the magnetic release fires between 5 A and 10 A, fast enough to clear a hard short but tolerant of brief starting surges. The 70 kA IEC 60947-2 rating is the headline number for industrial installations: it certifies the breaker can quench an arc at 70 kA prospective fault current, which is typical for main distribution boards or sub-distribution close to large transformers. The DC rating of 15 kA per IEC 60947-2 covers battery-backed circuits or DC bus feeds. The UL 1077 / CSA C22.2 No. 235 rating of 5 kA is the supplementary-protector figure for North American panels — lower because the standard's test circuit is different, not because the hardware is weaker. Thermal derating is baked into the spec: the breaker carries 1 A at 45 °C, drops to 0.98 A at 50 °C, and 0.95 A at 55 °C. ## Integration and physical fit This MCB snaps onto a DIN rail (quick assembly system per) and occupies 2 modular width units — 36 mm wide, 90 mm tall, 76 mm deep, with an installation depth of 70 mm. Mounting position is any, which helps when you're packing breakers into a tight gland-plate layout. Protection class is IP20 with connected conductors — this is a panel-mount device, not a field-mounted unit. Sealable allows a lockout tagout hasp to be fitted for LOTO procedures.","metaTitle":"Siemens SENTRON 5SY8501-7 MCB, 1P+N, C-Char, 1A, 70kA","metaDescription":"Siemens SENTRON 5SY8501-7 miniature circuit breaker, 1P+N, C characteristic, 1A rated, 70kA breaking capacity IEC, 2-module, IP20, halogen-free.
