The Siemens 5SN6010-7CN is a SENTRON miniature circuit breaker (MCB) in a compact 1P+N design — switches both line and neutral in a single 18 mm wide module. Rated 10 A at 30 °C with a C tripping characteristic, it handles the inrush from small motor and lighting loads in residential and light-commercial distribution boards. Breaking capacity is 6 kA per EN 60898, sufficient for most final subcircuits in a TN or TT system.
Ratings and derating
The 10 A rating holds at 30 °C ambient. At 40 °C it derates to 9.5 A, and at 45 °C to 9.3 A — so a panel running warm near the top of a DB may need to step up one frame size if the continuous load is close to 10 A. Insulation voltage is 250 V AC, with a maximum operating voltage of 250 V for single-phase operation. Overvoltage category III and pollution degree 2 suit fixed-installation downstream of the main distribution board.
Mounting and integration
Snaps onto standard DIN rail (EN 60715) and occupies one modular width (18 mm). Installation depth is 70 mm, overall depth 76 mm. Mounting position is any orientation — no derating needed for horizontal or inverted fit. The neutral pole switches internally, so no separate neutral bar is required for the outgoing circuit. Touch protection is built in; IP20 rating applies with connected conductors.
Lifecycle and sourcing
Current-production part in the SENTRON portfolio. The 5SN6010-7CN is specified into new BOMs and stocked for MRO spares. Availability and current pricing confirmed at quote time against an RFQ — sourced through independent distribution channels.
Environmental and compliance
Halogen-free and silicon-free construction — important for installations where outgassing could affect sensitive contacts or electronics. Sealable design allows the installer to lock the toggle position. Vibration-resistant per IEC 60068-2-6. Ambient operating range covers -25 °C to +60 °C with humidity limits (85% rF up to 45 °C, 43% rF above). Energy limitation class 3 means it lets through less energy during a fault than class 1 or 2 devices, reducing stress on downstream components.
