Siemens 5SL3113-7MB — 1-pole C-curve MCB, 13 A, 4.5 kA
The C-curve means it trips between 5 and 10 times rated current — suited for general-purpose loads like lighting, socket circuits, and small motor starters where moderate inrush is expected. The 4.5 kA SCCR at 400 V covers most residential and light commercial distribution boards in IEC markets.
Physical fit and panel integration
Single-pole format, 18 mm wide (1 MW), 90 mm tall, 76 mm deep with 70 mm installation depth. Mounts in any position on a standard 35 mm DIN rail. IP20 with connected conductors — suitable for enclosed distribution boards only, not for wet or dusty environments. Rated for overvoltage category III and pollution degree 2, which is the standard for fixed-installation switchgear in buildings. The housing is halogen-free and silicon-free — relevant if the panel is in a clean-room or corrosive-gas sensitive area.
