What this MCB does and where it fits
The Siemens 5SL3006-7 is a SENTRON miniature circuit breaker with a C-curve trip characteristic, meaning it's built for moderate inrush loads like small motor starters, lighting banks, and transformer primaries — the kind of load where you need the magnetic trip to hold off for a short pulse without nuisance tripping. It's a 1P+N design, so it switches both the line and the neutral, and it's rated for 230 V AC (single-phase) with a breaking capacity of 4.5 kA per IEC/EN 60898-1 and GB/T 10963.1. The 18 mm width (one modular unit) snaps onto a standard DIN rail, and the mounting position is unrestricted — you can orient it any way the panel layout demands.
Panel integration notes
The 5SL3006-7 installs in any DIN-rail enclosure with a 70 mm installation depth — the overall depth is 76 mm, so leave clearance for wiring and the front toggle. It's rated IP20 with connected conductors, which is standard for enclosed panel mount — not for wet or washdown areas. The terminals accept supplementary devices (auxiliary contacts, shunt trips, alarm switches) if you need remote status or trip indication.
Environmental and compliance details
Operating temperature range is -25 °C to 45 °C at up to 85% relative humidity, with derating above 45 °C up to 60 °C at 43% rF. The housing is halogen-free and silicon-free, which matters for panels in clean-room or corrosive-gas environments where outgassing can cause contact issues. It's rated for overvoltage category III and pollution degree 2, so it's suited for fixed-installation distribution boards in residential and light-commercial infrastructure.
