It is rated for 400 V AC (440 V max in multi-phase or single-phase operation) and 60 V DC (72 V DC max). The 5SY7332-7 carries three distinct breaking capacity ratings depending on the standard applied: 15 kA under EN 60898-1 (the household / commercial standard), 25 kA under IEC 60947-2 (the industrial standard), and 5 kA under UL 1077 / CSA C22.2 No. 235. The DC rating of 15 kA at 60 V DC (per IEC 60947-2) covers battery-backed control circuits or DC bus protection. It is certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077. The UL 1077 listing means it is recognized as a supplementary protector in North American panels — not a branch-circuit rated breaker per UL 489, but acceptable for protecting individual loads downstream of a branch-circuit OCPD. ## Mounting and integration — DIN-rail fit and panel space The terminals accept combined top and bottom wiring. Supply can come from either end. ## Environmental range and materials Operating temperature spans -40 °C to 75 °C, with humidity derating: 95% RH up to 55 °C, 55% RH up to 70 °C, 35% RH up to 75 °C. Energy limitation class 3 means this MCB limits the let-through energy (I²t) to a low level, reducing arc-flash hazard downstream and allowing smaller cable sizing in coordinated panels.","metaTitle":"Siemens 5SY7332-7 SENTRON MCB, 3P C-Curve, 15/25 kA","metaDescription":"Siemens 5SY7332-7 SENTRON 3-pole miniature circuit breaker, C-curve, 15 kA (EN 60898) / 25 kA (IEC 60947-2).

However, the 5SY7332-7 has a higher breaking capacity (25 kA vs typically 10–15 kA under IEC 60947-2), which may require verifying that the panel's SCCR and upstream coordination are adequate — and that the terminal style matches your existing wiring. A direct swap without checking these points is not recommended."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY7332-7","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SY7332-7 when reusing this data.
