Its 70 kA interrupting capacity at 400 V AC per IEC 60947-2 means it can clear high-fault currents in industrial panels without cascading upstream — critical for selectivity in a motor control centre or distribution board. On DC circuits it still delivers 15 kA at 60 V (72 V max), covering battery-backed or solar combiner applications. Any mounting position is allowed; the breaker is sealable for tamper-proofing in metered or safety-critical feeds.","metaTitle":"Siemens 5SY8202-7 SENTRON MCB, 2-Pole C-Curve, 70 kA IEC","metaDescription":"Siemens 5SY8202-7 SENTRON 2-pole MCB, C-curve, 70 kA at 400 V AC per IEC 60947-2, 15 kA DC, IP20, halogen-free.
