Product details

The Siemens SENTRON 5SL1110-7MB is a 1-pole miniature circuit breaker rated 10 A with a C tripping characteristic, designed for 230/400 V AC residential and infrastructure branch circuits. 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.

Frequently asked questions

What is the breaking capacity of 5SL1110-7MB?

3 kA according to IEC 60947-2 at 230/400 V AC. 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.

Will 5SL1110-7MB drop into a panel specified around 5SL4106-7CC without rewiring?

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.

Where can I buy 5SL1110-7MB and how is it quoted?

Sourced and quoted to order against an RFQ through independent industrial-automation distribution. Availability and current pricing are confirmed at quote time — send the quantity and target delivery window for a firm line.
