That 6 kA figure is the maximum fault current it can safely interrupt at 400 V AC; for a residential or light-commercial distribution board fed by a typical utility transformer, it covers most downstream faults without needing an upstream fuse to back it up. The C-curve means it trips between 5× and 10× rated current — standard for mixed lighting and small-motor loads where you want to ride out inrush without nuisance trips. ## Panel fit and deployment context At 36 mm wide (2 modular width units), it snaps onto a standard DIN rail and needs 70 mm of installation depth behind the panel cover. The IP20 rating with connected conductors means it's protected against finger contact once wired — fine inside a locked enclosure, not for wet or outdoor exposure. Mounting position is unrestricted, which simplifies layout in a crowded distribution board. ## What it does not carry No auxiliary contact or shunt-trip add-on is supported — the product extension for supplementary devices is listed as 'No'. If you need remote signaling or undervoltage release, you're looking at a different MCB platform or an external contactor arrangement. The breaker itself is halogen-free and silicon-free, which matters for clean-room or corrosion-sensitive environments.","metaTitle":"Siemens 5SJ6213-7FC SENTRON MCB, 2-Pole C 13A, 6kA","metaDescription":"Siemens SENTRON 5SJ6213-7FC miniature circuit breaker, 2-pole, C-curve, 13 A, 6 kA breaking capacity per EN 60898. 36 mm wide, IP20.
