The C-curve (5–10× In magnetic trip) means it handles moderate inrush from motor starters and lighting ballasts without nuisance tripping — the standard choice for general-purpose branch circuits in residential and light commercial infrastructure. The 3 kA breaking capacity per IEC 60947-2 defines its fault-interrupt limit; this is not a high-fault panel breaker — it belongs downstream of a higher-rated upstream device in a coordinated distribution board. ## Panel fit and integration Snap-on DIN-rail mount, 3 modular width units (54 mm wide), 90 mm tall, 76 mm deep with 70 mm installation depth. IP20 with conductors connected — standard for enclosed distribution boards. Mounting position any, so it fits vertical or horizontal busbars. Sealable, halogen-free, silicon-free. Overvoltage category III, pollution degree 2. The 2.9 W power loss per pole at rated current matters for thermal derating in a crowded enclosure — check the total dissipation against your panel's thermal budget.","metaTitle":"Siemens 5SL1325-7MB SENTRON MCB, 3-pole C 25A, 3kA","metaDescription":"Siemens 5SL1325-7MB SENTRON miniature circuit breaker, 3-pole, C-curve, 25A rated, 3kA breaking capacity per IEC 60947-2, 230/440V AC.
