The dual breaking-capacity rating is the key specification for this MCB. For comparison, a sibling like the 5SY4101-7CV carries the same dual ratings but with a B-curve trip characteristic, which trips faster on lower overcurrents and is better suited for resistive loads or long cable runs where nuisance tripping from inrush is a concern. The C-curve on this 5SY4104-7XX02 is the standard choice for motor branch circuits and mixed loads. Snap-on DIN rail mounting, any position. Width is 1 modular unit (27 mm), installation depth 70 mm, overall depth 76 mm. It also carries a UL 1077 / CSA C22.2 No. 235 rating of 5 kA for North American acceptance. Halogen-free and silicon-free construction. Energy limitation class 3, overvoltage category III, vibration resistance per IEC 60068-2-6. The sealable design allows lockout/tagout for maintenance safety.","metaTitle":"Siemens 5SY4104-7XX02 SENTRON MCB, 1P C-curve, 10kA IEC 6089","metaDescription":"Siemens SENTRON 5SY4104-7XX02 miniature circuit breaker, 1-pole, C-curve, 10 kA per IEC 60898-1.
