Breaking capacity and trip curve for panel coordination
The Siemens 5SL4306-7 is a 3-pole SENTRON miniature circuit breaker rated 6 A with a C-curve trip characteristic, designed for 400 V AC three-phase circuits. Its 10 kA breaking capacity is certified to both EN 60898 and IEC 60947-2, meaning it can safely interrupt fault currents up to 10 kA without upstream device intervention — a key figure for panel selectivity studies.
Active production and sourcing posture
The 5SL4306-7 accepts add-on auxiliary switches, shunt trips, and alarm contacts via the SENTRON accessory system, so a single panel stock keeps spares common across multiple circuit configurations.
Occupies 3 modular width units (54 mm) on a DIN rail, with a 70 mm installation depth and 76 mm overall depth. Mounting position is unrestricted — install it in any orientation inside the enclosure. Rated for ambient temperatures from -40 °C to 75 °C, with IP20 protection (finger-safe when conductors are connected).
