It also carries a UL 1077 supplementary-protector listing at 5 kA, so it qualifies as a recognized component for North American panel builds where the branch-circuit OCPD is upstream. ## Breaking capacity across standards This breaker is rated for three different fault-current regimes depending on which standard governs your installation: 6 kA under IEC/EN 60898-1 (the residential/commercial MCB standard), 30 kA under IEC 60947-2 (the industrial standard for switchgear and controlgear), and 15 kA at DC per IEC 60947-2. The DC rating (15 kA at 60 V, max 72 V) covers battery-backed control circuits and solar-combiner applications. Width is 18 mm (one modular unit), depth 76 mm, height 90 mm. ## Compliance documentation The breaker is certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA C22.2 No. 235. It is halogen-free and silicon-free — relevant for clean-room or high-reliability environments where outgassing matters. The sealable design (tamper-evident cover option) is available for installations requiring lockout-tagout compliance. Standard documentation includes the manufacturer's declaration of conformity covering the applicable directives; RoHS and REACH compliance is standard for current-production Siemens SENTRON parts.","metaTitle":"Siemens 5SY6104-6 SENTRON MCB, 1P B-Curve, 6kA IEC, 30kA UL","metaDescription":"Siemens 5SY6104-6 SENTRON miniature circuit breaker, 1-pole B-curve, rated 6 kA per IEC/EN 60898-1 and 30 kA per IEC 60947-2.
