What it is and what it does
The Siemens SENTRON 5SL6006-6 is a 1P+N miniature circuit breaker with B-curve tripping, rated 6 kA breaking capacity per IEC/EN60898-1 at 230 V AC. It switches both line and neutral, and the neutral pole is switched — important for isolating the circuit on single-phase residential or infrastructure panels where a shared neutral bus isn't assumed.
Key ratings and what they mean for fit
B-curve characteristic means the magnetic trip operates at 3 to 5 times rated current — suited for resistive and general lighting loads where inrush is low. The 6 kA breaking capacity (per IEC/EN60898-1) covers most residential and light commercial service-entrance fault levels; for higher prospective short-circuit currents you'd step to a 10 kA or 15 kA rated MCB. Rated operational voltage is 230 V AC single-phase, with insulation voltage (Ui) at 250 V AC. Overvoltage category III and pollution degree 2 mean it's rated for fixed-installation distribution boards, not for outdoor or wet-location use without an enclosure. Mechanical life is 10 000 operating cycles typical — adequate for a distribution breaker that sees infrequent switching; not a load-break switch for daily use.
Mounting and integration
Snap-on DIN-rail mount, 1 modular width unit (18 mm wide). Installation depth is 70 mm; overall depth including terminals is 76 mm. Mounting position is unrestricted — horizontal, vertical, or inverted — which helps when laying out a tight panel. IP20 with connected conductors; sealable for tamper-proofing (padlock or seal wire). Halogen-free and silicon-free construction — relevant for panels in clean environments (data centers, medical) where outgassing from a fault could contaminate sensitive equipment.
