It carries a 3 kA breaking capacity per IEC 60947-2, which means it can safely interrupt fault currents up to that level without upstream damage in a standard panelboard. ## Fit and footprint Occupies a single 18 mm modular width unit on a DIN rail, with a depth of 76 mm and height of 90 mm. The 70 mm installation depth leaves room for wiring behind the rail in a standard enclosure. IP20 with connected conductors — fine for a dry indoor panel, not for washdown zones. Mountable in any position, rated for ambient temperatures from -40 °C to 75 °C, and halogen-free / silicon-free construction. Overvoltage category III and pollution degree 2 suit it for fixed-installation distribution boards. ## Sourcing and lifecycle Listed as current-production — no phase-out or last-time-buy notice on this order code. Sourced and quoted to order against an RFQ through independent distribution channels; availability and current pricing confirmed at quote time.","metaTitle":"Siemens 5SL1110-7MB SENTRON MCB, 1P C-curve 10A 3kA","metaDescription":"Siemens SENTRON 5SL1110-7MB miniature circuit breaker, 1-pole, C-curve, 10A, 230/400V AC, 3kA breaking capacity per IEC 60947-2.

That is the fault-interruption rating for this single-pole C-curve breaker — sufficient for most residential and light commercial sub-distribution boards where the upstream device limits the prospective fault current."},{"question":"Will 5SL1110-7MB drop into a panel specified around 5SL4106-7CC without rewiring?","answer":"Yes — same 18 mm width, same 76 mm depth, same 90 mm height, same DIN-rail mounting, same single-pole form factor. The 5SL4106-7CC is a 6 A version; the 5SL1110-7MB is 10 A. If the branch circuit load and wire sizing support 10 A, it swaps in directly. No terminal relocation or panel modification needed."},{"question":"Where can I buy 5SL1110-7MB and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent industrial-automation distribution.
