The Siemens 5SL1113-6MB is a SENTRON miniature circuit breaker, single-pole, rated 13 A at 30 °C with a B tripping characteristic — meaning it trips instantaneously at 3 to 5 times rated current, which is the standard choice for resistive and general-purpose loads in residential and light commercial panels where inrush is low. Breaking capacity is 3 kA per IEC 60947-2, which covers most domestic and small commercial fault levels; if your installation requires a higher SCCR (e.g., 6 kA or 10 kA per EN 60898), you would step up to the 5SL6... series peers. Rated operational voltage is 230 V AC single-phase, 440 V AC multi-phase — the 1-pole design switches the line only, with no switched neutral.
Sealable design allows tamper-proof locking in metering or rental applications. Halogen-free and silicon-free construction suits environments sensitive to outgassing, such as clean rooms or telecom shelters.
