The Siemens 5SL6301-6CC is a 3-pole miniature circuit breaker rated 400 V with a 6 kA breaking capacity, B-curve trip characteristic, and 1 A rated current. It is an active-production part from the Basic Devices family.
At 1 A it's a low-current branch protection, typically feeding a control circuit or a single small load rather than a general-purpose lighting final subcircuit. It interrupts a fault up to 6 kA without welding the contacts or cascading upstream. Three-pole configuration switches all three phases simultaneously — required for three-phase control circuits or small three-phase loads.
Panel integration and compliance
Snap-on DIN rail mount (EN 60715) — standard 35 mm profile. Occupies three modular spaces (each 17.5 mm wide). The B product class indicates return-restricted distribution; this is a Siemens-controlled channel part, so source it through an authorized Siemens partner or an independent distributor who can trace the lot code. RoHS compliant since June 2013. REACH candidate list disclosure is available on request. No export restrictions under German AL or US ECCN (AL: N / ECCN: N) — standard commercial goods for global shipment.
