The D tripping characteristic means it tolerates high inrush currents (5–10× rated current), so it's the right choice for motor loads, transformers, or welding equipment where the start-up surge would nuisance-trip a C-curve breaker. Breaking capacity is 10 kA under both EN 60898 and IEC 60947-2, which covers most distribution panels in residential and light commercial infrastructure. At 2 modular width units (36 mm), it fits standard DIN-rail enclosures. ## Panel fit and integration Mounts in any position on DIN rail, with an installation depth of 70 mm and overall depth of 76 mm. The 2-pole footprint takes up 2 modular width units (36 mm). IP20 with connected conductors — suitable for enclosed distribution boards, not for wet or outdoor locations. Sealable, halogen-free, and silicon-free construction. Accepts supplementary devices (auxiliary switches, shunt trips, undervoltage releases) for expanded functionality. ## Electrical specs at a glance Rated for 400 V AC, 50/60 Hz, with a maximum operating voltage of 440 V AC in multi-phase operation. DC rating caps at 72 V. Power loss per pole is 2.7 W in hot operating state at rated current. Mechanical service life is 10,000 operating cycles typical. Overvoltage category III, pollution degree 2, energy limitation class 3.","metaTitle":"Siemens 5SL4232-8 SENTRON MCB, 2P D 32A 10kA","metaDescription":"Siemens 5SL4232-8 SENTRON miniature circuit breaker, 2-pole, D-curve, 32A, 10kA breaking capacity per EN 60898 / IEC 60947-2.

The 5SL4232-8 is a 2-pole D-curve 32 A in 2 MW (36 mm). They share the same 10 kA breaking capacity, voltage rating, and SENTRON platform, but the pole count, trip curve, and current rating are different — they are not drop-in substitutes without rewiring and recalculating the load."},{"question":"Will the 5SL4232-8 drop into a panel specified around the 5SL4363-7?","answer":"No — the 5SL4363-7 occupies 3 MW (54 mm) while the 5SL4232-8 takes 2 MW (36 mm). The DIN-rail mounting is the same, but the pole count, trip curve, and current rating differ. You would need to rewire the circuit and verify the load matches the 32 A D-curve rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL4232-8","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/5SL4232-8 when reusing this data.
