The Siemens 5SL6306-7 is a SENTRON 3-pole miniature circuit breaker rated 6 A with a C tripping characteristic, designed for 400 V AC multi-phase operation at 50/60 Hz. Its 6 kA breaking capacity is certified under both EN 60898 and IEC 60947-2, meaning it safely clears fault currents up to that level in residential and infrastructure distribution boards. The C-curve (5–10× In) handles moderate inrush from motor starters and lighting ballasts without nuisance tripping — a common choice for general-purpose branch circuits.
Dimensions and mounting
Occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. Mounting position is unrestricted, and the IP20 rating (with connected conductors) is standard for enclosed panel environments. The housing is halogen-free and silicon-free — relevant for installations where outgassing must be minimized, such as in clean rooms or near sensitive contacts.
Environmental range and accessories
Rated for ambient temperatures from -40 °C to 75 °C, covering most indoor and sheltered outdoor enclosures. The breaker accepts supplementary devices (auxiliary switches, shunt trips, alarm contacts) for remote status or emergency-off integration. The enclosure is sealable, which helps prevent tampering in accessible locations.
