Product details

The Siemens SENTRON 5SL1102-7MB is a 1-pole miniature circuit breaker, C-curve, rated 2 A at 230/400 V AC.

At 2 A rated current, that means the magnetic trip holds through about 10 to 20 A of starting surge before clearing a hard short. Rated for 50/60 Hz, 230 V single-phase or 400 V multi-phase (line-to-line).

In the panel

The 18 mm width (1 MW) means it occupies one slot — easy to swap into an existing row. Installation depth of 70 mm plus a bit of wiring clearance fits most distribution boards. Sealable terminals (yes) allow a lead seal for tamper-proofing in metering or rental applications.

Frequently asked questions

What is the breaking capacity of the 5SL1102-7MB?

The breaking capacity is 3 kA rated value according to IEC 60947-2 at 400 V AC. This is suitable for residential and light commercial branch circuits where fault current is limited.

How do I get pricing and availability for the 5SL1102-7MB?

Submit an RFQ against this part number. We source through independent distribution and confirm current pricing and availability at quote time — no stock figures on the public page.

What is the width and depth of the 5SL1102-7MB?

Width is 18 mm (1 modular unit), depth is 76 mm, height is 90 mm. It occupies one slot on standard 35 mm DIN rail.

What compliance documentation is available for the 5SL1102-7MB?

The breaker is halogen-free and silicon-free. It carries an IP20 protection class with connected conductors and is rated for overvoltage category III, pollution degree 2. Standard SENTRON documentation includes CE declaration and manufacturer's test certificates.
