It provides a 10 kA breaking capacity under both EN 60898 and IEC 60947-2, so it safely interrupts fault currents up to that level on a 230/400 V AC supply — sufficient for most residential and light commercial distribution boards. The single-module width (18 mm) and 76 mm depth let it snap onto standard DIN rail in any mounting position, which simplifies panel layout when you need to pack multiple poles into a tight enclosure. It is IP20 rated with connected conductors, meaning it is protected against finger contact but not water ingress — standard for inside a distribution cabinet. ## What the ratings mean for fit The C-curve (tripping characteristic class C) means the magnetic trip activates at 5 to 10 times rated current — designed for moderate inrush loads like small motors, lighting banks, and transformer-fed circuits where a B-curve would nuisance trip. The 32 A rating on a 1-pole breaker handles single-phase branch circuits up to that current; on a 230 V line that covers roughly 7.4 kW of resistive load. The 10 kA breaking capacity at 400 V matches the typical prospective short-circuit current on the secondary side of a residential or light commercial transformer, so the breaker clears a bolted fault without needing an upstream current-limiting device in most installations. Energy limitation class 3 means it limits let-through energy well — less stress on downstream wiring and equipment during a fault. ## Panel integration notes The 5SL4132-7 snaps onto 35 mm DIN rail per EN 60715. Its 18 mm width occupies one modular unit, so 18 breakers fit per meter of rail. The 70 mm installation depth leaves clearance for wiring behind the busbar stack. The breaker accepts supplementary devices (auxiliary switches, shunt trips, undervoltage releases) — the product extension feature is enabled. Terminals accept copper conductors up to 25 mm²; strip length per Siemens standard practice. The sealable design allows the installer to lock the handle position after commissioning, preventing unauthorized toggling on critical circuits.","metaTitle":"Siemens 5SL4132-7 SENTRON MCB, 1P C 32A 10kA","metaDescription":"Siemens SENTRON 5SL4132-7 miniature circuit breaker, 1-pole, C-curve, 32 A, 10 kA breaking capacity per EN 60898.

That means it can safely interrupt a fault current up to 10,000 A without welding contacts or causing internal damage."},{"question":"Will the 5SL4132-7 fit in a panel designed for a 3-pole 5SL4363-7?","answer":"Not without rewiring. The 5SL4132-7 is a 1-pole breaker (18 mm wide), while the 5SL4363-7 is a 3-pole unit (54 mm wide). The depth and height are identical at 76 mm and 90 mm, so the physical depth fits, but the busbar arrangement, phase connections, and DIN-rail space allocation are completely different. You would need to re-engineer the distribution block."},{"question":"Where can I buy the 5SL4132-7 and get a price?","answer":"The 5SL4132-7 is available to order through independent industrial-automation distribution.
