The Siemens SENTRON 5SL4113-7RC is a 1-pole miniature circuit breaker (MCB) from the 5SL4 design family, rated 13 A with a C tripping characteristic and a 10 kA breaking capacity per EN 60898. It operates on AC supplies at 240/415 V, covering single-phase line-to-neutral (250 V) and multi-phase line-to-line (440 V) applications. The C-curve means it trips between 5 and 10 times rated current — standard for general-purpose protection of resistive and moderate inductive loads in residential and infrastructure panels.
What the ratings mean for fit
The 10 kA breaking capacity (per EN 60898) is the maximum prospective fault current this MCB can safely interrupt at its rated voltage — sufficient for most residential and light commercial service entrances where the available fault current stays under that threshold. The 13 A rating and C-curve make it a direct fit for 13 A ring-main or radial circuits in UK/EU-style distribution boards, protecting socket outlets and fixed appliances with moderate inrush (e.g., small pumps, refrigeration compressors). At 18 mm wide (1 width unit), it occupies a single module on a standard DIN rail — essential for high-density panels where every slot counts. The 76 mm depth and 70 mm installation depth mean it fits flush in most domestic consumer units and small distribution boards without protruding past the enclosure door. IP20 with connected conductors is the norm for enclosed panel mounting; no special sealing required. Rated for ambient temperatures from -40 °C to +75 °C, so it handles unheated utility rooms, outdoor enclosures in cold climates, and high-heat conditions near transformer vaults. The halogen-free and silicon-free construction matters for installations in hospitals, data centers, or other environments where corrosive off-gassing during a fault must be minimized.
Integration notes
Snap-on mounting to 35 mm DIN rail per EN 60715; any mounting position accepted. The sealable design (lockable toggle) allows the facility manager to lock the breaker in the ON or OFF position for lockout/tagout compliance without additional hardware. Neutral conductor switching is not built in — this is a single-pole device switching only the phase; the neutral bus bar runs uninterrupted. Overvoltage category III and pollution degree 2 ratings confirm it is suitable for fixed-installation distribution boards where transient overvoltages (e.g., from utility switching) are expected and the environment is non-conductive but may have occasional condensation. The energy limiting class 3 (highest) means it restricts let-through energy well, protecting downstream wiring and equipment during a short circuit.
