That 10 kA figure means it can safely interrupt a fault current up to 10,000 amps, which covers the vast majority of residential and light commercial distribution boards. The C-curve (tripping between 5 and 10 times rated current) is the standard choice for general-purpose loads like lighting, socket outlets, and small motor circuits where you need moderate inrush tolerance without nuisance trips. ## Panel fit and integration At 18 mm wide (1 MW), this breaker snaps onto a standard DIN rail and occupies a single modular slot. Installation depth is 70 mm, so it clears a 76 mm deep enclosure back wall with a few mm to spare for wiring. Mounting position is unrestricted — any orientation works. The IP20 rating (with connected conductors) is typical for enclosed distribution boards; it's not rated for washdown or outdoor exposure. Sealable terminals are provided for anti-tamper requirements. ## What the ratings mean for the buyer The 2.92 W power loss per pole at rated current adds up to about 8.8 W total for the 3-pole unit — worth factoring into enclosure thermal calculations if the board is densely populated. Energy limitation class 3 means it limits let-through energy effectively, reducing stress on downstream components during a fault. The -40 °C to 75 °C operating range covers unheated utility rooms and outdoor enclosures in most climates. Halogen-free and silicon-free construction matters for sensitive environments like clean rooms or areas with corrosion-sensitive contacts.","metaTitle":"Siemens 5SL4325-7RC SENTRON MCB, 3P C-25A 10kA","metaDescription":"Siemens SENTRON 5SL4325-7RC miniature circuit breaker, 3-pole, C-curve, 25A, 415V AC, 10kA breaking capacity per EN 60898.
