Product details

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).

Frequently asked questions

Is the 5SL4306-7 suitable for 3-phase applications?

Yes — it's a 3-pole breaker rated 400 V AC with multi-phase operation up to 440 V AC, making it a direct fit for three-phase 400/440 V line circuits.

Is the 5SL4306-7 suitable for DC applications?

Its DC rating is limited to 72 V maximum. For higher DC voltages or DC-specific trip curves, a dedicated DC-rated MCB should be selected.
