Breaking capacity is rated 10 kA per DIN EN 60898-1 and 20 kA per IEC 60947-2, with a DC rating of 15 kA at 60 V per IEC 60947-2 — meaning it safely interrupts faults up to those levels without welding contacts or cascading upstream. The higher 60947-2 figure applies when the MCB is used in industrial distribution, not just household-style installations. Rated operational voltage is 400 V AC (440 V max multi- or single-phase), with a DC rated voltage of 60 V (max 72 V).
Panel fit, mounting, and environment
The 5SY4332-6KK11 occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm — standard for a 3-pole MCB in a SENTRON sub-distribution board. Ambient temperature range is -40 °C to 75 °C, with humidity derating: 95% RH up to 55 °C, 55% RH up to 70 °C, and 35% RH up to 75 °C. Designed for railway applications (per) and mechanical engineering/industry (per), with a sealable option for tamper-proof installations — the screw-seal cap on the toggle prevents unauthorized switching in public-access or safety-critical panels.
The MCB is designed and tested to DIN EN 60898-1 (household-type) and IEC 60947-2 (industrial) — the dual rating means it's accepted in both residential and industrial distribution boards across Europe, UK, and most markets that adopt IEC standards. No UL/CSA listing is stated in the evidence, so for North American panels a different SENTRON variant (UL 489 listed) would be needed. The part is halogen-free and silicon-free, which supports RoHS and REACH compliance statements from the manufacturer. The energy limitation class is 3, meaning it limits let-through energy to a low level — good for protecting downstream equipment during a fault.
