Its breaking capacity is 4.5 kA according to EN 60898 and 5 kA per IEC 60947-2 — the higher IEC figure is what matters when the breaker sits in an industrial panel where the prospective fault current may exceed the residential standard. The C-curve means it trips between 5 and 10 times rated current, so it handles moderate inrush from small motor loads or transformers without nuisance tripping, while still clearing a hard fault fast enough to protect downstream wiring. ## Where it fits and how it mounts Occupies 3 modular width units (54 mm wide) on a standard DIN rail. Depth is 76 mm, installation depth 70 mm — leaves clearance behind the panel door for wiring and the sealable cover. Mounting position is any, so it works in vertical or horizontal DIN-rail orientation. Rated IP20 with connected conductors — fine inside a closed panel, not for wet or outdoor locations. Power loss per pole is 3.1 W at rated current in hot operating state. In a tightly packed enclosure with multiple breakers, that heat adds up — account for it in your thermal derating if the ambient exceeds 40 °C. ## Lifecycle and sourcing Rated for 10 000 mechanical operating cycles typical, which is standard for a residential/infrastructure MCB in this class. Overvoltage category III and pollution degree 2 suit it for fixed-installation distribution boards.","metaTitle":"Siemens 5SL3332-7 SENTRON MCB, 32 A, 3P, C-Curve, 4.5 kA","metaDescription":"Siemens 5SL3332-7 SENTRON miniature circuit breaker, 32 A, 3-pole, C-curve, 400 V AC, 4.5 kA (EN 60898).

The IEC figure governs its use in industrial panels where fault current coordination is required."},{"question":"Will the 5SL3332-7 fit in a panel specified for the 5SL4363-7?","answer":"Yes — both share the same 76 mm depth, 54 mm width, 90 mm height, and 3-module DIN-rail footprint, so the 5SL3332-7 drops into the same panel cutout and busbar arrangement without rewiring. The difference is breaking capacity: the 5SL4363-7 carries 10 kA (both standards) while this unit carries 4.5/5 kA."},{"question":"What compliance documentation does Siemens provide for the 5SL3332-7?","answer":"The SENTRON series carries the standard CE marking for the European market. The unit is halogen-free and silicon-free, which helps with outgassing requirements in clean environments. Specific RoHS/REACH declarations are available from Siemens upon request."},{"question":"Where can I buy the 5SL3332-7 and get current pricing?","answer":"This part is sourced and quoted to order against an RFQ through independent industrial distribution.
