At 400 V AC (phase-to-phase) the 20 kA figure gives headroom for high-fault industrial supplies; the 5 kA UL 1077 / CSA 22.2 No. 235 rating covers North American acceptance on branch circuits. Certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA 22.2 No. 235, so it carries the documentation a maintenance technician needs for panel acceptance: the dual standard listing covers both European and North American compliance scopes in a single part number. Snap-on DIN-rail mount, any position. The quick-assembly system and combined top/bottom terminals speed wiring in multi-pole panels. Sealable with a lead seal for metering or safety isolation circuits. Ambient range -40 °C to 75 °C covers most indoor and sheltered outdoor enclosures; humidity derating applies above 55 °C (max 95% RH to 55 °C, dropping to 35% at 75 °C).","metaTitle":"Siemens 5SY4632-6 SENTRON MCB, 4P B-Char, 10kA IEC","metaDescription":"Siemens 5SY4632-6 SENTRON miniature circuit breaker, 4-pole, B-curve, 10 kA per IEC 60898 / 20 kA per IEC 60947-2.
