Siemens 5SL4532-7 SENTRON MCB — 32 A, C-curve, 1P+N, 10 kA
It carries a 10 kA breaking capacity under both EN 60898 and IEC 60947-2, which means it can safely interrupt fault currents up to 10,000 A without upstream damage — a standard rating for residential and light commercial distribution boards. The C-curve (5–10× In) is the default choice for general-purpose loads with moderate inrush: lighting banks, socket outlets, small motor circuits, and control transformers. At 32 A, this breaker covers a 230 V AC branch circuit pulling roughly 7.3 kW of resistive load, or a mixed load with some motor starting.
The 5SL4532-7 occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and height of 90 mm. Mounting position is unrestricted, which simplifies layout in crowded panels.
The dual-standard rating means the breaker is certified for both the household (EN 60898) and industrial (IEC 60947-2) application scopes, giving flexibility in specification. Voltage: rated 230 V AC for single-phase operation, with a maximum of 250 V AC. DC rated value is 72 V maximum — usable for DC circuits only within that limit. Frequency: 50/60 Hz, covering both common mains frequencies.
