The Siemens SENTRON 5SN6006-7CN is a 1-module-wide miniature circuit breaker (MCB) rated 6 A, C-curve, with a 6 kA breaking capacity per IEC/EN60898-1. It switches the neutral conductor and accepts supply from either end. The C curve handles moderate inrush loads like small motors or lighting banks without nuisance trips.
DIN rail fit and panel space
Snaps onto standard DIN rail and takes up just 18 mm of panel width. Depth is 76 mm, so it clears most 80 mm deep enclosures. Mounting position is any, which helps when you're packing breakers into a tight gland plate layout.
What the ratings mean for the buyer
The 6 kA breaking capacity at 230 V AC is the fault current it can safely interrupt — fine for residential and light commercial infrastructure. The C-curve trips between 5 and 10 times rated current, so it won't drop out on a motor start or capacitor bank inrush. Ambient temperature range -40 to 75 °C covers unheated utility rooms and outdoor cabinets. IP20 with conductors connected means it's not washdown-rated; keep it inside the panel.
Standards and compliance
Certified to IEC/EN60898-1 and GB/T10963.1. Halogen-free and silicon-free — relevant for clean-room or high-reliability installations where outgassing matters. Degree of pollution 2 and overvoltage category III suit fixed-installation distribution panels.
