It delivers a 10 kA breaking capacity certified to both EN 60898 and IEC 60947-2, so it handles fault currents up to that level without upstream cascading in residential and light commercial distribution boards. Occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and 70 mm installation depth behind the panel. The IP20 rating applies with connected conductors — standard for enclosed distribution boards. Mounts in any position, and the sealable design allows lockout-tagout provisions on the toggle. Rated for overvoltage category III and pollution degree 2, which covers fixed-installation distribution panels. The C-curve (5–10× In) is the standard choice for moderate inrush loads like small motor starters, contactor coils, and lighting circuits. Mechanical service life is 10,000 operating cycles typical. Power loss per pole at rated current in hot state is 0.9 W — negligible for thermal budgeting in a populated enclosure. Halogen-free and silicon-free construction matters for environments where outgassing during a fault could corrode nearby contacts or optics. Ambient temperature range spans -40 °C to 75 °C, so it suits unheated enclosures in cold climates or warm machine cabinets.","metaTitle":"Siemens 5SL4305-7 SENTRON MCB, 3P C 0.5A 10kA","metaDescription":"Siemens 5SL4305-7 SENTRON miniature circuit breaker, 3-pole, C-curve, 0.5 A, 400 V AC, 10 kA breaking capacity per EN/IEC.
